The best fertile period for ovaries between 25 and 28 years old

　　Physiologically speaking, female The reproductive system mainly includes the ovaries, Uterus , hormone secretion, etc. The endocrine system is strong during adolescence, and both the ovaries and uterus are still developing. After the age of 20, the development matures, the ovaries secrete hormones and ovulate regularly, and the golden period of fertility begins. The age of 25-28 is precisely the period when the egg quality is relatively high and the hormone secretion level is the most stable, so it is also the best period for female fertility.

　　Eggs cannot regenerate, and once the eggs are exhausted, ovarian function decline will be irreversible. Yang Dongzi said that a woman ovulates 400 to 500 eggs in her lifetime. As a woman ages, her ovaries undergo a series of changes: in the newborn period, the ovaries have about 2 million follicles. In childhood, most of the follicles will degenerate, and by adolescence, only about 300,000 follicles will remain.

　　In a woman's lifetime, generally only 400 to 500 follicles mature and ovulate. The ovary of an adult woman weighs approximately 5 to 6 g. menopause The ovaries then atrophy and become smaller. The quality of eggs includes fertilization ability and cleavage ability. Between the ages of 25 and 28, eggs have strong fertility and the best quality. If the fertilization ability is poor, fertilization and pregnancy will be difficult, and the cleavage function will be poor. fetus Quality declines and children are prone to malformations.

　　Older mothers are much more likely to affect their fetus than older fathers because male sperm It can be copied, but women are always in a state of consumption. Therefore, the older the woman is, the older the eggs are, and the quality of the eggs will naturally be poorer, which can easily cause chromosomal abnormalities in the fetus.

　　Theoretically speaking, the longer it takes to start sexual life, the greater the damage to the uterus. In addition, artificial abortion, Gynecology Inflammation, infection, etc. will destroy the uterus, and the more damaged the uterus, the greater the impact on the implantation and development of the fertilized egg. Compared with the state of the uterus between the ages of 30 and 25-28 years old, the nutritional level of the uterus has lagged far behind the former.

　　Many white-collar women in companies often postpone childbirth due to work reasons, which is actually against the laws of nature. Therefore, experts propose: to give birth in the most suitable reproductive period, give birth to healthy The better the chances of the baby, and the better the maternal recovery.
