Approximate fertility window what does it mean. What does the period "fertile day" mean for a woman. Ovulation and fertile window

Any woman who wants to get pregnant, or, conversely, seeks to avoid it, should know the capabilities of her body. Many of the fair sex have an idea about the calendar method of pregnancy planning, but much less women are familiar with the term fertile days.

What is fertility, fertile period, fertile days

Fertility is the ability to get pregnant and have a healthy baby.

Fertile days (period) are a few days in the menstrual cycle that occur before ovulation and immediately on this day. The maximum chances of conception fall 5 days before ovulation, as well as on the day of its onset. It is this period of time that is fertility.

Ovulation is the moment when a mature egg is released from the ovarian follicle into the fallopian tube and its further advancement to the uterus. According to doctors, the greatest chances of pregnancy are the day before ovulation. At the same time, spermatozoa can live in the vagina for several hours, and in the uterus for about 5 days. After the onset of ovulation, the egg has a day for fertilization.

The menstrual cycle lasts an average of 28 days, and ovulation occurs in the middle of it.

Such a calculation is averaged, as a rule, a woman has individual deviations in the cycle.

Fertility age

Nature is conceived in such a way that a person is ready for offspring only in a certain life period. In men, the reproductive function is preserved until old age, while in women this period is not so long. The fair sex can become pregnant and bear the baby only until the onset of menopause.

Fertility in women persists on average between the ages of 15 and 49 years. Therefore, you should not postpone pregnancy for a long time, since at a young age the prognosis of conception is more favorable.

How to calculate fertile days for a woman

The menstrual cycle varies in duration for different women. An individual calculation of the fertile period allows you to more accurately know the day of ovulation, which significantly increases the chances of conception. Fertility in women can be calculated in several ways.

The calendar method consists in maintaining a calendar of the fertile period. In this case, it is necessary to mark the date of the first and last days of menstruation, as well as the middle of the cycle. It is at this time, as a rule, that ovulation occurs. A significant drawback of this calculation method is that it is only suitable for those who have a stable menstrual cycle. If the duration of the cycle is variable, then it is almost impossible to calculate the fertile period by this method.

The calendar method for determining fertile days is effective by no more than 60%.

The fair sex, who carefully listens to her body, notices that some changes occur in it with a certain frequency. Thanks to such observation, fertile days can be recognized. During this period, the nature and volume of vaginal mucus changes. During the fertile period, it becomes more abundant, and outwardly similar to egg white.

This is due to the fact that the woman's body is rebuilt for the most favorable time for conception. At the same time, fertility can also manifest itself with other symptoms: pulling pain in the lower abdomen and increased sensitivity of the mammary glands.

If such symptoms are not typical for a woman in each cycle, then this may indicate the presence of an infection.

The fertile period can also be calculated by measuring the basal temperature. The method consists in regularly measuring the basal temperature in the rectum or vagina. This should be done in the morning immediately after sleep, without turning over. Also, for the reliability of the results obtained, it is better to use the same thermometer all the time.

It is important when using this method and measuring basal temperature at the same time. Its value can be influenced by sex, drinking, any disease or nervous shock. Data of daily measurements must be entered in the table. The fertile period begins with a slight rise in basal body temperature, which remains at this level for several days. At this time, ovulation occurs.

Fertile days can also be determined using a special test that is sold in pharmacies. They should be started approximately 5 days before the expected moment of ovulation. Such a test works similarly to a pregnancy test, and luteinizing hormone is detected.

Before using the ovulation test, read the instructions that come with it. Testing is carried out daily at the same time once or twice a day. It is necessary to collect urine in a clean container and place a test strip in it for a certain time. Just before ovulation, the amount of luteinizing hormone rises sharply, which is what the test tracks.

A positive test result indicates that fertility is now high, that is, the female body is ready for fertilization.

What can cause fertility

The factors that affect fertility, doctors include: the age of a woman over 30 years old, overweight, abnormal development of the egg, genital tract infections, inflammatory processes and other causes. It is desirable that in case of infertility a woman is examined not only by a gynecologist, but also by an endocrinologist and a nutritionist.

Normal fertility is greatly influenced by the lifestyle that a woman leads. She needs to fully eat, get enough sleep, observe all the rules of personal hygiene, and not enter into casual intimate relationships. Being healthy is necessary not only for the sake of conception, but also in order to endure a healthy baby. To plan a pregnancy, you need to understand what fertile days are and learn how to calculate them.

Fertile days and ovulation may be absent. The following factors influence this: a failure in the hormonal background or a deterioration in the functioning of the thyroid gland. Natural violations include the lactation period - breastfeeding the baby. Since the list of root causes is not small, you need to consult a doctor to find out.

How to increase fertility in women?

It would seem that you need to conceive? If there is a sexual partner, then pregnancy will not be long in coming. But, unfortunately, not everything is as simple as we would like. The hormonal background of the female body is constantly undergoing various changes. This is what causes frequent mood swings. Even slight increased nervous excitement can affect a woman's ability to become pregnant.

Here are some tips that we hope will come in handy if you want to increase your fertility:

  1. Watch your kilos. Both an excess amount of fat, and its lack, negatively affect ovulation. With an increased number of fat cells, the body turns on the production of hormones that prevent the normal functioning of the ovaries. And the lack of fat, on the contrary, inhibits the process of producing the necessary hormones that are directly related to this process. As a result of such changes, the periodicity of the menstrual cycle is disturbed, and with it the regularity of the onset of ovulation. Physical activity will help control excess weight. But you have to be careful not to overdo it here. Very often, professional athletes experience irregularities in the monthly cycle. This happens from an overstrain of the body, due to which there is a failure in the hormonal background.
  2. Eat right. For a woman's health, a balanced and proper diet plays an important role. The female body needs foods rich in protein, iron, zinc and vitamin C. Their deficiency delays the onset of menstruation, and therefore ovulation occurs less frequently. By the way, athletes often suffer from a lack of zinc. A sufficient amount of animal protein is found in meat, eggs, fish and dairy products. Vegetarians can be advised to eat legumes with rice, as well as the inclusion of soy products in the diet.
  3. Give up cigarettes. It has long been proven that smoking ages the body of a woman. The chemicals in cigarettes damage some functions of the reproductive system. If we consider the ovaries of a 30-year-old woman who smokes, their functional capacity is comparable to that of a 40-year-old woman's ovaries. This indicates an early extinction of the body. But if a woman quits smoking, then she will have every chance to restore some of the functions of the reproductive system.
  4. Watch your cycle time. The norm is considered to be an interval of 25-35 days. If the gap between periods is longer, for example, 42 days, then ovulation will occur according to the cycle. To calculate your fertile days and plan for conception, you need to calculate the day of ovulation. It is considered the most fertile day of the cycle. The days preceding the beginning of the process are also favorable for conception. Fertile are 4-5 days before the release of the egg from the ovary. After the end of the process, the probability of conception is reduced to zero. Usually, for an approximate calculation of the day of ovulation, the duration of the cycle is divided in half. Suppose if the cycle is 28 calendar days, then the probable day of ovulation will be on the 14th day from the onset of bleeding. But since you need an accurate calculation, you should use a special test that shows the days of approaching ovulation. Such a test is sold in all pharmacies. Another way is to measure your basal body temperature daily.
  5. Keep calm. Danish scientists conducted research and came to the conclusion that during psychological stress, the hormonal background becomes similar to that which the body experiences during increased physical exertion. You need to teach yourself to get out of this state using the methods of meditation, relaxation or yoga. Swimming is a great way to relieve stress. It’s good to remember your hobbies, which can replace going to a psychotherapist.
  6. Eliminate alcoholic drinks. Alcoholic beverages change the level of the hormone estrogen in the blood. It is he who is responsible for the fertility of a woman and the ability to maintain pregnancy in the early stages. Insufficient levels of estrogen prevent implantation of a fertilized egg in the uterine cavity. However, according to scientists, one glass of wine at dinner will not harm a woman's health and her reproductive ability. You should also pay attention to drinks that contain caffeine. American OB-GYNs believe that more than 2 cups of black coffee a day contributes to miscarriage. Therefore, in order to endure and give birth to a healthy child, alcohol and coffee should be abandoned.
  7. Be proactive in your intimate life. It has long been proven that menstrual irregularities most often occur in women who do not live a regular sexual life.
  8. Avoid douching. In the vagina there is a special microflora that performs a protective function. During douching, this layer is washed off and there is a risk of developing bacterial vaginosis.

Often, many are faced with the problem when they want a child, but it is impossible to conceive. Then many experts recommend checking the level of fertility and starting from it at conception. What is fertility in women and men, what factors affect it and what needs to be done to give birth to a healthy child?

What does fertility mean

Fertility is a concept that refers to the ability to produce a healthy child or children. Applies to both women and men. Its level shows how quickly a man or woman can conceive and bear a child.

When does the fertility window occur?

What it is? The window of fertility in women is the time when a child can be obtained. It comes only a few days out of the month. So, it lasts during the moment of the onset of ovulation and with it. For example, the cycle lasts 27 days, and the ovulation window will then fall in the middle of the cycle. A woman should understand about the onset of ovulation using a simple test - from the first day of the cycle to the last, measure the basal temperature. A sharp rise in temperature indicates the day of ovulation. That's when the days of fertility come.


You can increase fertility in women by:

  • freezing your own egg and introducing it into the body at the time when you want to get pregnant;
  • bringing your weight in order;
  • refusal of serious physical exertion, overwork and stress;
  • proper nutrition, rejection of bad habits;
  • selecting a contraceptive and performing ovulation tests;
  • denial of abortion.

You can increase the reproductive work of a man by:

  • avoiding prolonged exposure to frost testicles;
  • taking vitamin complexes and minerals, for example, zinc, selenium and vitamins A and E;
  • refusal to wear tight underwear;
  • maintaining the right lifestyle, preferably active;
  • performing simple exercises and being in nature;
  • refusal to wear the phone in the testicles.

Often, it is difficult to conceive a child. If you want to increase your fertility and get the baby you want, you need to follow some rules. We list the main factors on which the possibility of being a mother depends:


Male fertility depends on many factors. In particular, the main ones are:

  1. The presence of addiction, addiction to alcoholic beverages, drugs or smoking. All this causes disturbances in the field of the reproductive system, poor structure and quality of spermatozoa. So, gradually they become lifeless and even pathogenic.
  2. Long-term use of certain medications, antibiotics and antispasmodics. It is also possible to observe testicular and penile dysfunction while taking antidepressants.
  3. Long stay at enterprises where a large amount of harmful substances, radioactive elements and heavy ores are emitted;
  4. Constant presence in saunas, hot baths, baths and other hot places. All this affects the quality and quantity of fluid released from the penis.
  5. Venereal diseases, the presence of injuries in the ovaries and penis.
  6. Diseases associated with the presence inside the body of pathogenic microbes and viruses that disrupt the functioning of the ovaries.

Female and male reproduction depends to a greater extent on one hormone - testosterone. At the same time, it is good that in women it is normal or even slightly lowered, and in men it is normal or increased. Determine the level of male testosterone is checked by checking external signs, a blood test with saliva. In women, testosterone levels are also checked by external signs and by donating blood on a certain day of the cycle.

The possibility of being a parent can also be determined independently by looking at the factors presented above that affect it. So, if you often smoke, drink, take alcoholic beverages, work in hazardous factories, and more, your fertility rate will be lower than that of other people who lead an active and correct lifestyle, do not have a disease and work in non-hazardous enterprises.

Is it possible to get pregnant after 40 years?

Today, the most fashionable trend for women has become the birth of children in forty or after. Moreover, the first child is born, despite the possible consequences of such a decision. Of course, many doctors claim that it is possible to get pregnant and bear a healthy child at this age, but it is extremely difficult and dangerous, because there is a risk of giving birth to the first child with physical and mental pathologies.

If the decision is made to become pregnant at forty or later, it is important to undergo fertility tests for a woman, check the level of physical health and regularly see a gynecologist.

Learn the basic things about human fertility. Fertility or human reproductive ability is actually a very complex topic. Many factors can affect her, and a woman's fertile cycles are very complex without it. By having some knowledge of fertility and tracking fertile cycles, a couple can greatly increase their chances of conceiving.

  • A woman is considered fertile when her ovaries produce eggs that can be fertilized. Until the egg meets the sperm and attaches to the wall of the uterus, a woman cannot become pregnant.
  • The egg is ready for fertilization only within a few days. After the “window” has passed, menstruation will begin, and the lining of the uterus will come out along with the menstrual blood.

Increase your chances of conceiving with food and sex positions. It's important to understand what else you can do besides tracking your fertility cycle with a fertility chart. Learning these ways to stimulate fertility can increase the effectiveness of the schedule.

  • A variety of positions that a couple practices during sexual intercourse increase the chance of a sperm to connect with an egg.
  • Certain foods and drinks can increase the reproductive capacity of sperm and improve the environment of a woman's uterus.
  • Keep a close eye on your fertile cycle. Fertility is a very complex process, which is why it is so important to use a fertility chart and track cycles. By following just 4 simple steps, a woman can accurately determine the time of ovulation and plan the next intercourse for this period. It is impossible to guarantee that a couple will definitely be able to conceive a child, but following a fertility schedule dramatically increases the chances.

    Record your temperature. Tracking a woman's basal body temperature (body temperature during rest, measured after sleep) is one of the oldest ways to keep a fertility chart. It has been used for years to increase the chances of conceiving a child.

    • After ovulation, a hormone is produced that slightly raises the basal body temperature. By tracking basal temperature, some women can accurately determine the time of their next ovulation. Usually, the temperature rise is so slight that it is difficult to predict the time of the next ovulation. However, some women still manage to track their fertile cycles by measuring only their basal body temperature. It is important to take the temperature at the same time every day to get a complete and reliable result. It is recommended to have sex on the morning when you notice a slight increase in temperature. It takes about 12 hours for the egg to travel from the ovaries to the fallopian tubes. Having sex within 6 hours of noticing an increase in basal body temperature can increase the chance that a sperm will meet an egg.
  • Look out for cervical mucus (the mucus secreted by the cervix). Thickness of cervical mucus is often considered a better indicator of fertility than basal body temperature.

    • Cervical mucus performs different functions depending on a woman's cycle. When ovulation has not yet begun, cervical mucus is thicker and acts as a barrier for sperm to reach the uterus.
    • During ovulation, the consistency of cervical mucus changes. It becomes more stretchy and less viscous and serves as an insulating layer that helps the sperm get to the egg. When you notice that your cervical mucus has changed its consistency and has become more stretchy and transparent, similar to egg white, instead of being viscous and white, most likely you are in the most fertile phase of the fertile cycle for conception.
  • Track the beginning of your menstrual cycle. For some women, the best way to track your fertility cycle is simply by watching the start of your menstrual cycle. Ovulation most often occurs between 13 and 15 days after the start of the menstrual cycle. Depending on the length of your menstrual cycle, the most fertile days for conception may be 8 to 10 days after the end of the cycle. This method will help you determine the time period of about 7 days that is most favorable for trying to conceive. Using this method, women can determine the period of ovulation without measuring basal body temperature or examining the consistency of cervical mucus. Women who use all three methods at once can determine the period of ovulation with much greater accuracy.

    Track the number of sexual acts. Some couples believe that the surest way to conceive is to have sex every day. But it's not. Sperm will be more viable and make it to the uterus more likely if you only have sex a few times a month. By tracking your fertility cycle and only having sex when you are at your most fertile, you can increase the chances that sperm will actually enter the uterus and fertilize an ovulated egg.

    Did you know that a woman is only able to get pregnant for six days out of her entire cycle? This is known as the fertile window, women can become pregnant on the day of ovulation, or five days immediately before starting. Predicting your ovulation date and fertile window can be tricky, especially if your cycle is irregular, but the body transmits certain patterns that can help find clues as to when you're able to conceive.

    Regardless of the length or consistency of a woman's cycle, there are only as many as six days for each intercourse that can lead to conception. These days are known as the fertile window.

    Ovulation and fertile window

    While you may not have heard the term Fertile Window, chances are you may be familiar with ovulation. Ovulation is the phase of your cycle in which one of your ovaries releases an egg into the fallopian tube, where it awaits the company of one of your partner's sperm for fertilization. Once released, the egg has a lifespan of about 24 hours to be fertilized. If the egg is not fertilized, it will disintegrate and await your next period. Even though eggs are only viable for 24 hours, your partner's sperm are able to survive and fertilize them for up to five days after intercourse, so any intercourse during the five days of ovulation (the fertile window) can result in conception. However, the closer to ovulation you have sex, the more likely you are to conceive.

    When does the fertile window open?

    The old rules dictate that ovulation occurs about halfway through your cycle, or 14 days after you have your period. The relative date of ovulation can vary greatly from woman to woman, and even from cycle to cycle. The fertile window usually begins anywhere from a few days to a few weeks after the end of the period, depending on the length and sequence of the woman's cycle and any external factors such as stress or malnutrition, and ends the day after ovulation, which for women with the correct form 28 -day cycle will take about two weeks before the start of the next expected period. While this sounds nice and simple, it is rarely easy in practice, as women and cycles differ. Accordingly, one must look beyond the period to find out when ovulation occurs and pay attention to body signs and signals in search of a fertile window.

    While some women may have such regular cycles that they have no problem figuring out their fertile window, for most people, predicting ovulation accurately is much more difficult. Women in the past have relied on a number of different methods and tracked several different indicators to predict fertility.

    • Basal body temperature: Body temperature often drops just before ovulation starts and drops shortly after.
    • Cervical fluid: becomes thinner and more elastic before ovulation begins.
    • Physical Symptoms: Women often notice various physical or emotional symptoms at certain times during their cycle. Creating a model with ovulation can help predict the fertile window.
    • Ovulation Tests: These test strips look for the presence of luteinizing hormone (LH), the hormone that causes ovulation. Tests can tell you when ovulation is imminent and has begun.
