How to do an ovulation test correctly? How to do an ovulation test? When should an ovulation test be done? Test results

The life of a woman of childbearing age is greatly facilitated by special diagnostic methods. It is easy to use the ovulation test, the instruction of which fully explains how to use this method for diagnosing the moment of release of the egg.

Girls and women purchase ovulation tests only in 2 cases:

make sure that you are not “pregnant” in case of menstrual irregularities;
determine the most accurate day and date when the probability of conceiving a child reaches its highest level.

The category of people who do not plan to have a baby in the near future, using this test, will be able to determine the day of ovulation and thoroughly prepare for it, that is, choose the maximum method of protection in order not to become pregnant.

Girls who want to become a mother soon will be able to identify ovulation days. This will increase their chances of conceiving a child.

The meaning of the ovulation period

The menstrual cycle is a monthly change that occurs in the life of every woman of reproductive age. This period begins on the first day of the onset of menstruation and ends on the first day of the onset of the next menstruation. A normal monthly cycle lasts approximately 21-35 calendar days, depending on the physiological characteristics of the body of a particular woman. Each monthly cycle shows the girl's readiness for conception. By its nature, it goes through 3 main phases of development:

Follicular, which lasts about 2 weeks after the end of menstruation.
Ovulation. Its duration is only a few days. As a rule, a mature but unfertilized egg dies after 2 days. And already during the period of ovulation, the epithelial layer in the uterus is prepared for pregnancy. Ovulation is the period when the probability of conception is highest.
Luteal. If conception occurred in the ovulation phase, with the help of the hormone progesterone, the fertilized egg is introduced into the walls of the uterus. If not, rejection of the prepared epithelial layer takes place, the "yellow body" dies. Thus, the cycle ends, the next menstruation begins.

All women who wish to become pregnant should remember that conception is possible only if sexual contact occurs immediately before ovulation or within 24-36 hours after it.

What are the types of tests

You can buy an ovulation test at any pharmacy. If you have any doubts about which type and manufacturer to give preference to, you can seek help from your doctor or ask your friends. Using tests to determine pregnancy is quite simple. The mechanism of action of tests is very similar to the principle of operation of tests to determine pregnancy. Modern pharmacology offers various types of them. Basically, ovulation tests are carried out by dropping them into your own urine. In addition, some types of tests react to the composition of female saliva.

Typology of ovulation tests:

electronic;
test strips;
test cassettes;
jet.

Each of these types has its own advantages and disadvantages.

Characteristics of funds

Electronic - tests that resemble a tube of lipstick. It is they who show results under the influence of saliva. It turns out that during the ovulation period, the composition of female saliva changes - changes in the pattern of crystallization occur. To obtain a result, it is enough to place a little “reagent” on the lens and follow the data obtained for some time. How to use the ovulation test and how to decipher the result - all the necessary information will be indicated in the instructions for the test. Electronic tests are popular due to the reliability and accuracy of the results shown. However, their cost will be one level higher than the price of other types of tests.

Test strips. Outside and according to the principle of action, they are analogues of pregnancy tests. In order to get a result, it is enough to lower a strip of test with a reagent into a container filled with urine. Within 30 seconds you can see the information you need. The disadvantage of such tests is the low level of reliability. At the same time, today they are the most budget options due to their low cost.

Test cassettes. This type of test is the most convenient to use. They are also often referred to as test plates. The strip of paper on which the reagent is applied is inside the plastic case. To use the test, it is enough to put a drop of urine into a special hole or substitute plastic under a stream of urine. The result appears almost immediately. They are in high demand among women due to the good price-performance ratio. In addition, they are sold in packs, usually 5 pieces.

Inkjet. The newest type of all existing tests. It is believed that these tests provide the most accurate results, and are also the most highly sensitive. The result can be seen within a few minutes (usually 3-5) after exposure of urine to the reagent. Often, inkjet tests are sold in a kit with a pregnancy test. They differ from their counterparts in higher cost.

Important day calculation

cycle duration 21-22 days - ovulation occurs on day 6;
cycle duration 23-24 days - ovulation occurs on day 7;
cycle duration 25 days - ovulation occurs on day 8;
cycle duration 26 days - ovulation occurs on the 9th day.

The longer the menstrual cycle, the longer the period will be. That is, with a 27-day cycle, the ovulation period will fall on its 10th day, and so on. It is important to remember that in case of failures or irregularity of the monthly cycle, it is necessary to choose the shortest period in the last 4 months. Thus, the most favorable time for conception is calculated using the folk calendar method. Constant stress, the use of alcoholic beverages and other factors can affect the reliability of the calendar determination of the ovulation day. The advantage of this method is that it is free. Unfortunately, the accuracy of determining the result will be low. That is why modern women prefer to purchase a ready-made ovulation test in a pharmacy, which can more accurately predict its date.

The principle of the test

Despite the significant number of varieties of tests, they all use the same mechanism that helps determine the right date. In order to achieve the desired result, it is necessary to act exactly as the instructions for the test indicate. The functionality of the test to determine ovulation involves the presence of a number of antibodies that are able to determine the concentration of luteinizing hormone in the urine.

It should be remembered that almost all ovulation tests have the same level of sensitivity, the difference is only in the manufacturer of the product. To date, the most popular ovulation tests are Frautest, Eviplan and Solo. Which one to give preference to is a personal matter for every woman. Even one test from one manufacturer can show the reliability of the result, and there is no need to buy several packages from different pharmacological companies. The distortion of the results is possible only if there are irregular menstrual cycles. And this means that pathological processes in the hormonal background of a woman can manifest themselves.

By determining the ovulation period, you can even plan the sex of the unborn child. It should be borne in mind that this approach is not a 100% guarantee, but it is popular among many couples. It is believed that conception on the eve of ovulation implies an increase in the chances of giving birth to a boy, and sexual contact on days distant from it contributes to the birth of a girl. How true this theory is, you can understand by testing it in practice.

Rules for the procedure

To achieve an accurate result, you should carefully study the instructions for using the test. It is always attached to its packaging.

Steps to follow when performing an ovulation test:

fill the container (attached to the test) with urine for research;
open the hermetically sealed packaging with the dough (you need to pay attention so that there is no damage and environmental influences);
lower the test into a container with urine, leaving it for the time indicated in the instructions.

Regular measurement of basal temperature can increase the reliability of the information received.

In addition, it should be remembered that using an ovulation test while taking hormonal drugs simply does not make sense. This reduces the reliability of the information received. Even drugs containing hormonal substances used for external use (gels, ointments) can distort the result.

Before using the test to determine ovulation, it is not recommended to drink liquid in unlimited quantities (especially important in hot weather), as there is an increase in the amount of urine, as a result of which the level of luteinizing hormone concentration decreases. As a result, the test produces an incorrect result.

In the package, as a rule, manufacturers produce 5 test strips. Such a measure involves testing every 12 hours on the coming ovulation days. Thus, it is possible to most accurately determine the moment of onset of ovulation.

Subtleties in use

The instructions that come with pregnancy tests recommend using morning urine to get a high result. If we consider the mechanism, then such urine is not suitable for obtaining the correct information. In this case, in order for the effectiveness to be at a high level, a woman needs to refrain from urinating for 3-4 hours.

The test result can also be distorted if the woman is already pregnant or has recently given birth to a child. Also, the premenopausal period in women can provoke an incorrect display of the data obtained.

In addition, after receiving the test results, all questions can be discussed with the attending physician.

Compliance with simple rules will allow a woman to obtain reliable final data and, as a result, conceive a child in a specified period. It is important to note that if for several months in a row all attempts to get pregnant (with the establishment of the date of ovulation) do not bring the desired results, you should consult a doctor. It may be necessary to undergo special diagnostics and examinations in order to establish the reason that does not allow conception.

It's just great that most modern women prefer. They take it seriously. After all, a planned pregnancy prevents unnecessary accidents. That is, an examination of the health of spouses before pregnancy, a healthy lifestyle, proper nutrition greatly reduces the risk of the baby developing not only infectious diseases, but also various pathologies. At the same time, external factors also minimally affect the unborn child during a planned pregnancy. When planning a pregnancy, future parents are fully and comprehensively prepared for the appearance of a child.

In order to conceive a child, certain conditions must be met. First, you need an egg ready to conceive a child. It must mature, that is, pass ovulation(- this is the maturation of the egg). Secondly, spermatozoa are needed (viable, with good physical activity). Thirdly, you need an environment suitable for conceiving a child (in a woman's fallopian tube, conditions are usually ideal). When all three conditions are combined, it is not difficult to conceive a child.

First, the egg matures. She is viable for 48 hours, after which she dies. During ovulation, a woman's body is fully prepared for conception - the hormonal system provides the body with all the necessary hormones. Because of this, ideal conditions are created in the internal genital organs of a woman for spermatozoa to stay there, which, by the way, can exist there without harm to themselves for four to five days.

During intercourse, the seminal fluid enters the internal genital organs of the woman, and the spermatozoa strive with all their might to the egg. She is quite far away. Sperm must pass through the vagina through the cervix, which opens slightly during ovulation, then half of the sperm goes into one fallopian tube, the other into the second. Those spermatozoa that have chosen the right path overcome "tunnel" fallopian tube and reach the egg. They unite and secrete a special substance that “pierces” the dense shell of the egg. And only one sperm gets inside and merges with the egg.

So, one of the conditions for conceiving a child is it's ovulation day . When it starts and when it ends - you can determine.

Calculation of the day of ovulation

The day of ovulation can be determined by several methods.

With the calendar method, a woman must record the beginning and end on the calendar. If the menstrual cycle is 28 days, then ovulation begins around the thirteenth to fourteenth day. A more accurate day of ovulation with the calendar method can be found out only after five to six months. Because during this time, data on the cycle is taken, and then calculated using a special formula.

During (the temperature is measured rectally), the data is also recorded for several cycles, and then analyzed.

A blood test for ovulation hormone is done for a long time, and the result is usually provided after ovulation.

Quite accurately about when ovulation will occur, the ultrasound doctor will say. Ultrasound is very good at showing ovulation. But then again, you need to make an appointment with a doctor, pay a lot of money, get an appointment ...

Special tests determine the day of ovulation very effectively.

The essence of the ovulation test

There are about 400 eggs in a woman's body at birth. Two hundred eggs in each ovary. Only one egg matures every month. As it matures, certain female hormones are produced ( estrogens). They tend to accumulate. And during the day of ovulation, a woman forms hormone lutein- this is the essence of the ovulation test. Lutein can be found both in a woman's blood and in her urine. Ovulation Tests "work" like pregnancy tests - just hold the test in a glass of urine, one or two strips will appear.

Ovulation tests are quite affordable. You can buy them at every pharmacy. They most often look like strip strips. Many different pharmaceutical companies produce such tests. Ovulation tests have different sensitivity, different equipment and different cost. More sensitive ovulation tests, supplemented with instructions for use, are more expensive than regular strip strips. Information about such ovulation tests (those without instructions) can be found on the Internet, but the essence of the ovulation test does not change.

When is the best time to do an ovulation test?

Before you calculate the day of ovulation using the test, calculate the duration of the female cycle. Typically, the menstrual cycle lasts 28 calendar days. But for some it lasts longer, for others less. Then calculate the approximate day of ovulation. Take as a basis the shortest menstrual cycle. For example, 28 days is from the start of your period to the start of your next period. Ovulation will approximately begin on the eleventh day and will possibly continue for a week. Why a week? You only have two days to ovulate. But these two days "fall out" for any of the seven days. Considering that spermatozoa remain viable for five days, plus two days of ovulation, this is the week when there is.

On what day after menstruation should I take an ovulation test? You can calculate the day of ovulation using the test from the eleventh to the eighteenth day of the menstrual cycle.

But not always in women, the menstrual cycle is stable. It is often irregular. It depends on the characteristics of the female body, the work of the endocrine system, nervous work, a turbulent situation in the family, due to frequent stress or a shift work schedule.

In this case, if a woman wants to conceive a child, there is no need to spend extra money on tests to determine ovulation. First, on the second or third day after the end of menstruation, it is better to undergo an ultrasound examination. It will show how the egg has "grown". The doctor who conducts such studies will advise when it is better to start using ovulation tests in order to.

Tests to determine ovulation are best done twice a day - after sleep and before bed.

Instructions for using the ovulation test

Calculate the length of your menstrual cycle. An ovulation test is best done seventeen days before the start of the next menstruation (with a regular menstrual cycle). If the menstrual cycle is irregular, take the shortest menstrual cycle as a basis.
Collect urine in a clean cup, open the ovulation test and lower the strip to the desired mark (or drop urine on the test) into the urine for five seconds. Then take the dough out of the cup and place it on a dry, clean surface. After ten minutes, evaluate the result of the test.
Urine for the test should not be the very first. Due to the fact that there is the highest concentration of hormones. The test will show an incorrect result. The best time to collect urine is around ten in the morning and around eight in the evening.
Before testing, it is best not to urinate for four hours.
For the sake of the correct result, it is better not to drink a lot of liquid before the test.
You need to open and take the test out of the package right before testing. It is better not to touch the special part of the test with your hands so that the result is reliable.

How to find out the result of an ovulation test?

There is a control strip on the ovulation test. It always shows up.

Negative result: the test line does not appear or appears weaker than the control strip. This means that the amount of lutein in the body has not reached the desired concentration, and ovulation has not yet occurred.

Positive result: the test strip is the same color as the control or darker. This suggests that the concentration of lutein in the body is large enough, and ovulation will occur within 48 hours.

No result: There is no control or test strip. This indicates that the test is most likely defective or has expired.

The test showed ovulation, but it was not - why?

This happens when the hormonal system fails, when using certain hormonal drugs, immediately after childbirth (when the woman's hormonal system has not yet recovered), with hormonal diseases. During pregnancy, an ovulation test will also show a positive result, because the hormone lutein is very similar to the human gonadotropin hormone.

Types of tests to determine ovulation

Ovulation tests are very similar to pregnancy tests. The essence of the ovulation test is exactly the same as that of the pregnancy test. Types of ovulation tests - strip strip, test cassette, inkjet test, reusable test, electronic test.

test strip. Such a test is the simplest and cheapest of its counterparts. It is made of paper impregnated with a special reagent. The disadvantage of such a test is not very high accuracy.

Test cassette. It looks like a plastic box with a window. You need to drop urine on it, the result will appear in the window. Pretty reliable ovulation test, priced a bit more than a strip strip.

Inkjet test. This test does not have to be lowered into a glass of urine, but can simply be substituted under a stream of urine. He is very sensitive and reliable.

Multiple test. It is a device with a set of test strips. These strips need to be lowered into the urine and inserted into this device, which will show the result.

Electronic ovulation test. This test differs from other ovulation tests in that it reacts to female saliva. Saliva is brought under the lens and the pattern is evaluated under a microscope or sensor (included). What the pattern means is indicated in the instructions. The electronic ovulation test is expensive, but it is the most accurate ovulation test.

Most importantly, when determining ovulation, do not forget that ovulation tests only show the level of lutein, and not ovulation itself. Ovulation may start a little later or a little earlier.

What is the best ovulation test?

Frautest, Eviplan, Pharmasco and Clearblue- companies that produce the best ovulation tests.

Frautest

This five-day test will help a woman with a regular cycle determine the day of ovulation. The Frautest test is considered one of the most reliable. One package contains five sachets with strips and instructions for use.

A rather sensitive test - 30 mIU / ml - a positive result is determined 40 seconds after testing. Negative result - after 10 minutes.

Frautest thoughtfully packaged both the ovulation test and the pregnancy test together, which is a nice touch. In these "double" kits, in addition to five ovulation tests, there are two pregnancy tests, seven cups and test instructions.

In addition to strip strips, Frautest produces cassette tests to determine ovulation. They are very convenient with an irregular menstrual cycle, because there are as many as seven cassettes in the package. The cassette should be held under the stream of urine for several seconds.

Eviplan

This brand produces strip strips for determining ovulation and inkjet tests. Their sensitivity is 25 mIU/ml. The application is similar to that of Frautest ovulation tests. But the result is visible in five minutes.

There are five cassettes in the package of Eviplan inkjet tests. Instructions with questions and answers are also attached. Very hygienic for testing, Eviplan's inkjet tests always provide an accurate result.

"Solo"

The Pharmasco company produces inkjet and strip tests. There are 5 pieces in a package with jet dough. The kit includes instructions, where a special table will help determine the day when you need to start testing.

The strip test package contains five test strips, instructions for an ovulation test and a small gift - a free sensitive pregnancy test.

"clearblue"

This manufacturer produces a digital ovulation test. The Clearblue Ovulation Test is considered the most sensitive (hence the best) test for determining lutein hormone levels. The manufacturer indicates that the accuracy of the ovulation test is 99%. The result is determined after three minutes. During operation, the test strip indicator flashes.

The cost of this electronic test is quite high - seven hundred rubles.

Ovulation test - benefits

Ovulation Test - this is a very convenient form in order to calculate the day of ovulation. Neither the calendar method of calculating the day of ovulation, nor the measurement of basal body temperature, nor the calculations of computers and mobile applications can compare with ovulation tests. All of them are approximate and conditional. And almost all are uncomfortable for a woman. And the essence of the ovulation test is that it is still a chemical analysis based on the production of the female hormone lutein.

An ovulation test can be done at home, and even at the workplace. It is very simple to dip the strip into a glass of urine, and then evaluate the result. A positive test result will show much faster, a negative one a little later.

Almost always, an ovulation test package comes with instructions, and some tests are equipped with both urine collection cups and pregnancy tests.

Manufacturers of tests for determining the level of lutein in urine indicate on the packaging that test accuracy is 99% . And it is true. If the concentration of lutein in the urine is high enough, the test strip appears at the control level - just as bright and clear. If the female hormone lutein in the urine is not enough, then the test strip will be pale and fuzzy.

There are times when the stripes do not appear at all. Then the test can be considered invalid. He either expired, or he was originally defective.

Planning the gender of the child

Knowing the day of ovulation is possible. There is a doctor's theory Landrum Shettles.

The sex of the unborn child is determined by the chromosomes of the spermatozoa. If a sperm cell carries a male Y chromosome and it fertilizes an egg, it will be a boy; if a sperm cell carries two X chromosomes, it will be a girl. "Male" spermatozoa with a Y chromosome are more mobile than "female" ones with an X chromosome. And the “female”, with the X chromosome, are much more viable and stronger.

Dr. Shettles offered to create conditions for the birth of a boy. And if the parents want a girl, you need to neutralize the spermatozoa with the Y chromosome (they are not so strong and tenacious).

To do this, determine the day of ovulation (preferably with a test). If you want to conceive a boy, schedule intercourse two days before ovulation, during ovulation, and two days after ovulation. On all other days there is an opportunity to conceive a girl.

This method was effective in three cases out of four.

Dear women! Do not save on your health, and even more so in such an important matter as planning a pregnancy. Because a woman, unlike men, has a limited time for conception, bearing and birth of a child. A woman's childbearing age is not infinite. Especially after thirty-five years, when you count every day, expecting a long-awaited pregnancy.

At this time, she is ready for fertilization. Ovulation lasts about a day.

You can determine the time when this favorable period begins, on your own or with the help of a test. Many women know an independent approach: for example, it can be keeping a schedule. However, this method is quite laborious and requires constant monitoring, otherwise the moment will be missed. A simpler and more efficient way is a test.

What's this?

An ovulation test is actually a determination of the concentration of luteinizing hormone (LH) in the urine. This hormone, if the fertilization of the egg did not take place or the embryo did not take root, causes the endometrium to leave the uterus, i.e., menstruation. The maximum level of LH reaches for a period of time from 12 hours to one and a half days before ovulation. The instructions for use of each test describe in detail exactly how to perform and how to interpret the results.

Types and principle of operation

The tests work in different ways, but all species have one thing in common - they check whether the luteinizing hormone has reached its highest stage, which would mean that a mature egg is ready to appear. Urine is the most commonly tested physiological fluid, less often saliva. Any ovulation test works like a portable chemical laboratory: the reagent is the basis, the reaction is fast and the result appears up to 10 minutes.

The price tag for tests is the most diverse. The price depends on the chosen type and on the manufacturer.

Important! Be sure to read the instructions carefully before starting testing. Each test has its own nuances in use.

test strip

Represents the usual paper strips, divided into two halves. One half of the control, a small transverse stripe is applied to it. The second half is diagnostic; a reagent is applied to it, which, in fact, forms the basis of the test. Urine for analysis is collected in a container, then a strip is lowered there for just a couple of seconds. 5 minutes after extraction, you can see the result. If the color of both halves of the test is the same, or the diagnostic is darker, then the result is positive and a favorable time for conception has come. If the half with the reagent is lighter than the second, then the test is repeated the next day.

Test tablet

This is a plastic elongated tablet with two windows. Still such tests are called cassettes. It is necessary to drip urine into one window, and the result will appear in the other after a while. It is believed that compared to paper, these tests are more reliable, but keep in mind that they are also more expensive.

Did you know?Just one couple can conceive 60 billion unique people with different genetic codes.

Inkjet rapid test

Such diagnostics can be performed, as they say, “on the go”. The name itself speaks of how to use this ovulation test, since there is no need to collect urine in a container. The principle of operation is similar to a paper strip, the difference is only in the appearance and method of analysis. It is enough to direct the stream of urine to the reagent enclosed in a plastic case and then wait 5 minutes. By comparing the two control strips according to the instructions, you will get your result.

To correctly do a jet test for ovulation, it is necessary to direct the jet past before hitting the analyzer itself.

Portable reusable systems

An original device that combines elegant appearance and high accuracy of the result. This is a whole set, which is a mini microscope equipped with a light, and samples for comparison. Saliva, applied to a special glass, under a microscope will turn into an interesting pattern. It is his drawing that will need to be compared with samples showing the LH peak.

digital test

This type also works with urine. You can choose which method is more convenient for you to analyze - inkjet, or by typing urine into a clean vessel. The principle of operation is very simple: the device is electronic and does everything by itself. After the turned on device has come into contact with the analyzed liquid, it is laid out on a flat surface and waiting for a signal. Then look at the result on the screen.

When to do an ovulation test?

Ovulation occurs approximately in the middle. You should start checking in advance, without waiting for a clear two-week milestone. Each woman has her own cycle, and when to do an ovulation test is a purely individual matter. The countdown is from the first day. Based on it, choose an approximate middle and step back for another two or three days. For example, if the cycle is 30 days, then you should start checking for possible ovulation from the 12th day.

Menstruation is irregular, so in your calendar you need to choose the shortest period and focus on it.

Rules and results

There are a number of nuances that affect the desired result. Let's consider the main points.

How to conduct

After reading the instructions, you can start the test. General recommendations for everyone are as follows:

If the analysis is carried out for more than one day, then the time of the conduction should be unchanged.
The container for collecting urine must be clean.
The result does not appear immediately, but after 5 minutes (sometimes even more).
The most effective technique is to test every 12 hours rather than once a day.

Are the results always correct?

There are a number of factors that affect the test result. Usually, the manufacturer mentions them in the instructions for their product. Please note that in hot weather the result may not be accurate. On the eve of the test, it is necessary to exclude funds, as they can affect the result. Also, do not drink a lot of water and try to refrain from urinating for 4 hours before the test.

Important!Please note that the test may be defective. Just in case, it is better to buy several pieces at once.

When to start conception?

Most often, couples who have despaired of their attempts resort to tests to determine ovulation. But you should know that for such couples, and for those who just want to approach the matter responsibly and according to all the rules of modern science, you still need to visit a doctor first. The specialist will prescribe tests, possibly identify violations in the body that prevent the onset of pregnancy, and prescribe a course of treatment. Only after that it makes sense to start planning pregnancy, as well as conducting tests for ovulation.

The most favorable time for the proposed is the first ten hours after the release of the egg from the follicle.

How to do without a test

There are ways to determine ovulation that will allow you to do without a test. For example, regular measurement of basal temperature (measured rectally) throughout the entire menstrual cycle. Over time, you will notice that there is a day when the temperature drops by two to three tenths of a degree. And the next day it makes a jump of three or four tenths. So, the temperature "failure" is a sign of the breakthrough of the egg and its movement through the fallopian tubes. This method is considered very reliable, but still it is laborious and not suitable for every woman.

There is another way that allows you not to use ovulation tests - monitoring external manifestations. However, the method is considered the least effective, since not every woman has an ovulation period accompanied by pain in the lower abdomen, a change in the nature of the discharge, and an increased craving for sex.

Can it show pregnancy?

If a pregnant woman takes an ovulation test, it is quite possible that it will show her a positive result. The problem is that the analysis will show exactly the desired positive result, and not pregnancy. It's all about the hormones that affect the reagent. The technique of home analyzes is effective, but not absolutely accurate. Therefore, the reagent captures the raging hormone, and which one it can “mix up”.

In any case, if you have any premonitions after a positive ovulation, get tested for pregnancy - just in case.

Did you know?A sperm that fertilizes an egg travels a distance of 10 cm. By human standards, this is 6.5 thousand km.

Secrets and tricks: how to plan the sex of the child

This topic is covered with rumors, legends and popular beliefs to such an extent that it is not possible to understand all this fantasy. However, there are attempts at a scientific approach. For example, a group of doctors from Europe created a theory called "blood renewal". Its essence is that since a woman's blood is renewed every three years, and a man's - every four, it is possible to calculate who has more "fresh" blood and, accordingly, whose sex will dominate. To do this, we divide the age of the woman by three, and the age of the man by four. We compare the remainder: whoever has it less is the happy owner of fresher blood. The effectiveness of this method, which, by the way, many future parents believe in, is only a few percent. Even the ancient Chinese knew how to plan the sex of a child better than modern Europeans. Moreover, recent studies claim that everyone's blood is updated every 3-4 months. But those who have come true, sacredly and very convincingly believe in this method, as evidenced by numerous forums for young mothers.

By the way, it was in ancient China that they created a theory based on the age of the mother and the month of conception. Corresponding tables can be easily found on the Internet.

Finally, the most scientific method regarding ovulation. Spermatozoa carrying male chromosomes die before those carrying the female chromosome. Accordingly, if you have sexual intercourse clearly on the day of ovulation, carriers of the male chromosome are more likely to get to the egg first. If sexual intercourse occurs in a few days, by the time the egg is released, only female carriers remain.

The ovulation test is highly accurate, but you should not rely solely on this modern improvement to conceive a child. It is necessary to prepare, go to the doctor correctly and follow his recommendations. After all this, it remains only to wait for the miracle of the birth of a new life.

For a successful pregnancy, it is necessary not only the quality of the biological material, but also the ability to use it, namely, to calculate favorable days for conception. For this, schedules, calendars, observation of symptoms and ultrasound are used. One of the most reliable methods is determination by probing. To establish accurate results, you need to know how to do an ovulation test correctly.

Ovulation is the process of release of a mature oocyte from the follicular cavity through the action of luteinizing hormone and estradiol on the walls of the follicle. Before ovulation, estrogen predominates in the body, in the luteinizing phase -.

A high level of estrogen indicates a large follicle, as more and more shell cells are able to produce the hormone. A high concentration of estrogen is a marker for an LH surge. The peak concentration of the hormone in a woman's body is 1-1.5 days before ovulation. It is under the influence of LH that a rupture of the follicle is possible. The duration of the ovulatory process is 16-32 hours.

Before doing an ovulation study, you need to determine the days to start daily calculations. First, you should find out the duration of your own cycle. With a normal level of hormones, its duration is the same, and ovulation occurs with deviations of 1-3 days. With an irregular cycle, you need to fix the duration of the shortest of them within 6 months and count on it.

Normally, after ovulation, the luteinizing phase lasts 2 weeks. It is necessary to start measurements 17 days before the expected ovulation, that is, from the length of the menstrual rhythm, 14 days of the luteal phase must be removed from the end and 3 days to study the reaction of express diagnostics in dynamics. When conducting a study, one should strictly adhere to the instructions and the general rules described in detail in the instructions.

Using ovulation calculation methods helps to plan the sex of the baby. Spermatozoa with Y chromosomes are more mobile, but live many times less than those with X chromosomes. During fertilization, 2-3 days before ovulation, spermatozoa with Y chromosomes lose their mobility. This gives an answer to the question of how to conceive a girl.

When to do research

Before you do an ovulation test, you need to calculate the day of the cycle when it needs to be carried out. Consider the diagnosis of urine on the example of a 28-day menstrual cycle:

We subtract 17 from 28 days, it turns out that the first test needs to be done on day 11.
If there is a weak strip, the next test should be carried out on day 12 and until the brightness of both strips becomes the same.
Normally, with a 28-day cycle, ovulation occurs on day 14, which means that when testing for 1-2 days, you can see a positive result.

With an irregular cycle, the test is carried out on the shortest in 6 months. For the study, it will be necessary to analyze 2 times a day.

Testing should be done daily until a positive result appears. A negative result in a study for more than 5 days indicates problems with folliculogenesis, dysfunction of the endocrine system, or a sharp decrease in ovarian reserve, a shift in the ovulation period.

Urine diagnostics

It is necessary to judge which ovulation test to choose according to the reliability and comfort in conducting. An economical and effective gadget is the use of strip strips to determine the concentration of luteinizing hormone in the urine. When it is carried out correctly, it determines the day of the onset of the ovulatory period with 99% accuracy.

With an irregular rhythm, it is recommended to take a test with a large number of express strips, with a normal cycle, 5 devices are enough. Some manufacturers include diagnostics for pregnancy, making the calculation complex more convenient and complete. There are 4 types of urine tests on the market:

strip strips;
jet;
electronic;
reusable device.

With proper analysis, high-quality economical strip strips do not differ in information content from expensive electronic devices.

General rules for urine analysis

The informativeness of diagnostics lies in the strict observance of the rules for its implementation. In addition to the attached instructions, there are criteria that can affect the quality of the test material:

The amount of liquid drunk before the diagnosis affects the concentration of LH in the urine. This means that a normal amount of water must be drunk prior to the test, as concentrated or watery material may give a false positive or false negative result.
Strips must be vacuum sealed prior to use. If the integrity of the packaging has been compromised, this may cause false results.
For greater accuracy, it is better to conduct a study in the morning and in the evening. Before urine collection, you must refrain from emptying the bladder for 4 hours, which means that the first morning urine is not suitable for analysis.
Before testing, you need to study the instructions, since if the analysis is carried out incorrectly, the gadget may be mistaken.
Before use, it is necessary to stop taking hormonal drugs, as they reduce the reliability of the results.
With irregular cycles, the diagnostic results are not informative as a means of natural contraception.

Instruction

The instructions usually describe how to use the ovulation test, may indicate the general rules for conducting, the principle of operation of the device and the evaluation of the results.

For diagnostics using a strip strip, you must:

Take care of the hygiene of the genitals in advance.
Collect urine into a vessel after a 4-hour abstinence from urination.
After that, the strip strip must be lowered with a sensitive end into the liquid for 15-20 seconds and placed on a horizontal surface.
The result can be seen in 5 minutes.
If the test showed a weak second strip, a second test is recommended after 12 hours or a day.

Analysis of results

If before the analysis one strip was already present on the device, this indicates its unsuitability. A false result also occurs when liquid enters the boundary strip.

After counting 17 days from the end of the menstrual cycle, a test is performed, the results of which may be as follows:

On the first day of the study, a faint second line on the ovulation test may be observed. This indicates an insignificant concentration of LH, which means that the next test should be carried out in a day.
If after a day the second strip is seen better than during the first test, this indicates a gradual increase in the level of the hormone. In the future, it is recommended to do testing 2 times a day.
If the strip is pale or absent after testing for several days, this indicates a shift in ovulation, a violation of folliculogenesis, or diseases of the endocrine system.
If the band becomes brighter with each test, but its tone does not reach the concentration of the control band, the results may indicate that the result is weakly positive.
If the stripes during the test are equally bright or more saturated than the control, the result is positive.
In the absence of a control strip, most likely, either the packaging was broken, or the device was defective in production.

It is important to consider that the listed decryption options are based on the correct conduct of the test, which means that any violation of the instructions can cause a false positive result.

Inkjet ovulation tests

The inkjet test is an upgraded version of the strip strip. It is performed without urine collection. For probing, you need to substitute the sensitive end of the device under the stream of urine. The results of an ovulation test can be seen in a few minutes.

The convenience of this method of analysis is that for probing there is no need to look for a vessel and conduct urine sampling. The device is in a special plastic package that protects it from excess moisture. The test is recommended to be carried out 2 times a day to calculate the best time for conception.

Digital instruments - features of the result evaluation

An electronic ovulation test differs in the method of evaluating the result. The method of its implementation is the same as with the inkjet test, however, to establish the presence of the ovulatory process, there is no need to independently check the shades, compare the results with previously performed analyzes.

To conduct the test, it is necessary to open one of the strips, and then remove the special cap from the device. The device must be inserted into the holder so that the arrow on it coincides with the one on the device, after which a signal about the readiness of the test should sound for 1 minute.

After this signal, you need to substitute the device under the stream of urine for 5-7 seconds, if the urine was collected in advance, you need to place the sensitive end for 15-20 seconds, then you can postpone the test while waiting for the results. The device, 20 seconds after exposure to the liquid, should emit a signal about the readiness of the test, which indicates the correctness of the process.

The answer will appear on the screen in 2-3 minutes. There can only be 2 results:

an empty circle, which indicates a negative result and a low level of LH;
smiley, which means a high concentration of luteinizing hormone, and approaching ovulation.

Saliva testers - advantages

When examining saliva, there are no problems, such as recognizing a weak line on an ovulation test, there is no need to compare with previous tests. It is known that at the moment of release of the oocyte, salts form a pattern similar to the outlines of a fern leaf due to abrupt hormonal changes.

Reusable saliva tests are divided into mechanical microscopes and electronic ones. If ovulation has occurred, an electronic test shows that the result is positive, you can independently assess the state of saliva using a microscope. You can do an ovulation test in the morning and in the evening.

The device was created to determine not only the rupture of the follicle, but is a marker of other processes occurring in the body of a woman:

favorable days for conception;
cause of infertility;
the reason for the delay in menstruation;
the threat of miscarriage or fading of the fetus;
pregnancy up to 1-1.5 weeks;
assess the state of the hormonal background during menopause;
gender of the baby;
diseases of the reproductive system.

How to use

The reusable hormone tester is the most accurate test on the market.

For probing, you need to put a small amount of saliva or urine on a glass slide and observe the change in its appearance. This must be done with sterile instruments. Under the influence of estrogens, the salts in the test material, when dried, turn into strokes and lines, the location of which can be varied. It will depend on the concentration of estrogen in the body, which reaches its peak along with LH.

If, during the study on the approximate days of ovulation, the crystals do not change their structure, this may indicate late ovulation, impaired folliculogenesis, or pregnancy.

Which saliva test to choose

Reusable tests are expensive devices, but at irregular rates, they help to more accurately determine the rupture of the egg. Of the microscopes, the most common are Ovulux, Arbor Elite, MAYBE MOM. A popular electronic pocket "laboratory" in the post-Soviet space is D.

Outcome

An ovulation test is the best method of pregnancy planning, as it helps to determine the beginning of the process of rupture of the follicular membrane with 99% accuracy. To independently determine the day of the ovulation process, urine and saliva tests are used. Each of them has its own advantages, however, in choosing a planning system, one must proceed not only from convenience or price, but also from the quality and sensitivity of the instruments.

Regardless of the manufacturer of the test and its type, the most important thing is to follow the instructions and the general rules for testing.

You can conceive a child only during ovulation - during the release of the egg from the ovary. In women who have a 28-day menstrual cycle, this occurs on the 14th day, but it can happen earlier or later. Sometimes ovulation does not occur.

A woman who wants to get pregnant, using the test, determines the time of the release of the egg and the period of probable conception, planning an intimate relationship with a partner for this time.

The principle of the test is based on the registration of an increase in the level of luteinizing hormone (LH) during the release of the egg. A positive result means that the woman will be able to become pregnant within three days, and the probability of fertilization in the next 36 hours is maximum.

The test should be carried out at the same time - from 10.00 to 20.00. Urine collected in the morning is not tested. To catch the highest level of LH, testing is carried out twice a day. During this period, you can not drink a lot of fluids and take diuretics, and two hours before the test it is better not to drink at all. It is undesirable to be tested in hot weather or while taking any hormonal drugs - the result is distorted.

The principle of testing is similar to pregnancy testing, only the reagent is tuned to a different hormone.

Instructions for the test to determine ovulation

Devices for determining ovulation are available in several types:

Strip test - a strip with a control mark, lowered for 10-15 seconds into a container with morning urine. After 10 minutes, the result is evaluated. If ovulation has occurred and the LH level has risen, a second band will appear.
Tablet tests - plastic cases, absorbent like blotting paper. Urine is dripped into one window, and one or two stripes are visible in the other two or three minutes later.
Jet - does not require urine collection, so it is more convenient than the previous two. It is substituted under the jet during urination. The result is visible in a minute. With an increased level of luteinizing hormone, two strips will appear.
Reusable ovulation test consists of an electronic device and a set of interchangeable elements that are immersed in freshly collected urine. When using, you need to remove the device from the package, remove the cap, insert the test module until it clicks, wait for a notification that the device is ready for testing. After the dive, three minutes later, symbols will appear on the electronic screen. The circle means that ovulation did not occur and the LH level did not increase. The smiley indicates an increase in the concentration of luteinizing hormone.

In addition to tests based on urine analysis, there is a reusable system for diagnosing ovulation based on the study of saliva. This is a mini microscope that looks like a lipstick. Before ovulation or during it, a pattern similar to a fern leaf is visible on the glass. Saliva is applied in the morning on an empty stomach with the tongue or finger, avoiding the formation of bubbles. After drying, using a microscope, it is determined whether a pattern is visible on the glass by comparing it with a complete sample.

Tests produced by various manufacturers have their own characteristics, so before using, you need to carefully read the instructions for each of them.

What day after ovulation should I take the test?

The start of testing depends on the length of the menstrual cycle. As a rule, the test begins a couple of days before ovulation. More exact times are shown in the table. The duration of the intermenstrual cycle is determined by the interval between the first days of the next two periods.

Test start day	Cycle duration (in days)	Test start day

If the test remains negative for five days, then the egg did not leave the ovary and the menstrual cycle was anovulatory (no ovulation).

To obtain an accurate result of the start of testing, you should measure your basal temperature at the same time every day by inserting a thermometer into the rectum. Before ovulation, it fluctuates between 36.2 -36.8, and after the release of the egg, it rises to 37.1 -37.2.

Ovulation test results

When used correctly, tests show ovulation at 90-99%. The result is easy to read: two strips - there is ovulation, the absence of a second strip - no. Normally, during ovulation, the second strip is darker than the first. If it is too light, the LH level is low and there is no ovulation.

Ovulation test results

When using an electronic test, a smiley face lights up, and during the study of saliva, a “frost pattern” or a pattern similar to a fern leaf is visible.

Once the result is positive, no further testing should be done. You need to use these days for fertilization, and then check for pregnancy.

False positive result

If conception has already occurred, the result is false positive. The reagent works on chorionic gonadotropin.
An incorrect result is obtained with a metabolic disorder in a woman. The test responds to increased levels of ovarian and thyroid hormones, showing a positive result outside of ovulation. In such cases, you need to check with an endocrinologist. Sometimes the cause lies in ovarian tumors that change the hormonal background.

False negative result

This happens when the instructions for use are violated or when expired tests are used. Sometimes a woman is in a hurry and begins to be checked earlier than the days indicated in the table.
The result is distorted in the presence of diseases that reduce the excretory function of the kidneys or are accompanied by edema. In this case, there is luteinizing hormone in the body, but it is not excreted in the urine. In diseases of the urinary system, it is better to use a test based on the analysis of saliva.
It is not possible to track ovulation in women with irregular cycles, since the day of ovulation is difficult to predict.

It is interesting! With the help of an ovulation test, you can increase the likelihood of having a baby of a certain gender. X-chromosomes are slower, but "tenacious" To conceive a girl, you need to have sex a few hours after the appearance of the strip on the test, and to give birth to a boy, wait a couple of days when it becomes pronounced. The method does not give a 100% guarantee, but it works effectively.

How to choose an ovulation test

The most advanced ovulation tests are inkjet. They are easy to use, and the detection accuracy is 98%. Reusable devices with replaceable strips also work well. When using, pay attention to whether the special indicator is on.

The accuracy of cheap strips is lower, and the number of false negative results when using them is higher. Use requires strict adherence to the instructions. If the strip is slightly overexposed in the urine, the result will be incorrect - the paper will get wet and the picture will become fuzzy.

The reagent included in the devices and test strips is very sensitive and deteriorates if stored incorrectly and if the deadlines are not observed. To double-check, you need to purchase a test of a different design and manufacturer. This will let you know if the results are distorted during testing. Women in many countries have long abandoned cheap tests: why conduct a study whose results cannot be trusted.
