The female body is full of secrets and features. Unlike men, the body of a representative of the weaker sex is subject to cyclical changes. This article will tell you about the features of the female body. You will find out how many eggs a woman has. Also find out interesting facts about the development of this gamete.
Female body
The body of the fairer sex is created to reproduce offspring. It is in this process that the main part is the eggs. It is worth saying that male fertility is also necessary for fertilization. Only when these two parts merge, an embryo forms, which subsequently becomes an embryo.
How many eggs does a woman have?
The sex of the unborn baby is laid in the womb at about 8 weeks of development. It is during this period that ovaries and the uterus begin to form in future girls. Up to the 20th week of development, the number of female follicles is growing. It reaches its peak approximately in the middle of pregnancy. How many eggs does a woman have at this moment? Scientists say that the number of gametes in this period is from 6 to 8 million.
Next, the inverse transformation occurs. Female gametes begin to pass the selection. However, most of them disappear. By the time of birth, about one million follicles are in the ovaries of the girl. However, not all of them will be able to bring offspring.
The beginning of puberty
How many eggs does a woman capable of fertilization have? By about 12-17 years old, the girl is faced with the first menstruation. After that, the female cycle is established within one year. From that moment, the fair sex can become a mother. A healthy woman has between 10 and 20 ovulations per year. During this period, the fair sex has about 300 thousand eggs. This figure is decreasing every month.
A major role is played by diseases of the reproductive system. If a woman for one reason or another removes part of the ovary or organ completely, then the number of gametes capable of fertilization is significantly reduced. Also, various hormonal drugs have a great influence on the number of eggs. So, taking oral contraceptives inhibits the maturation of follicles and stops ovulation. Is it possible to save part of the cells in this way? Doctors give an affirmative answer to this question.
According to statistics, by the age of 35, about 25 thousand cells remain in the ovaries in women. If, from the beginning of puberty, a representative of the weaker sex begins to take oral contraceptives, then there is a chance to increase this figure.
Ovulation
How many eggs does a woman mature each month? It all depends on the state of health of the reproductive system and genetic predisposition.
In an average woman, at least 10 eggs should leave the ovary per year. Doctors allow two or three anovulatory cycles that do not follow each other. There are also representatives of the fair sex, in which more than one gamete can stand out in one menstrual cycle. Most often, these are the ladies in whose family the birth of two or more children was observed simultaneously.
Conception
How much does an egg fertilize in women? Scientists call the time period from several hours to a couple of days.
It is worth noting that sperm can live in the female body for up to one week. That is why contact is not always needed during ovulation for fertilization. Male gametes may wait for a follicle to rupture in the fallopian tubes, reproductive organ, or cervical canal. As soon as ovulation occurs and the cell is released from the follicle, the sperm penetrates into it.
Features of the structure of germ cells
How many chromosomes are there in an egg? Doctors have established the fact that every month a woman develops cells that are different in structure and content. So, normally the sex gamete contains 24 chromosomes. It is these eggs that are found in most cases. However, if ovulation occurred, as a result of which a gamete with a large set of chromosomes came out, then there is a chance of having a baby with pathological syndromes.
Conclusion
Now you know the main interesting facts about the eggs and their number. Currently, doctors have developed laboratory studies that allow you to find out how many eggs are left in the body of a woman. To do this, you need to take tests for follicle-stimulating, luteinizing and anti-muller hormones. The study is carried out using venous blood for several days. The data will assess the health status of the reproductive function of any woman. Keep your germ cells under control and always be healthy. I wish you success!
