let go of the third child, in addition to discussing whether to give birth or not, whether it can be born smoothly has gradually troubled more and more couples. Data from the National Bureau of Statistics shows that among the age proportion of registered women in my country, the proportion of women with non-best childbearing age aged 35 and above is increasing year by year. Late marriage and late childbearing and late childbearing are also highly coincidental. At present, the infertility rate of couples of childbearing age in my country has risen to about 12% to 18%.
This is an amazing number, meaning that in every 5 to 8 couples, one couple is facing difficulties in giving birth. Infertility refers to those who have not contraceptive after marriage, have normal sex life, live together for 1 year but have not been pregnant.
The incidence of infertility is gradually increasing and it is showing a trend of youth. So what exactly causes infertility ?
Both factors or unilateral factors may lead to infertility. Among infertile couples, the female factor accounts for 40% to 45%, the male factor accounts for 25% to 40%, the male factor accounts for 20% to 30%, and the unknown cause accounts for about 10%.
At present, the mechanism of infertility in women is not clear. It may be due to the disorder of the immune mechanism of the pelvic and uterine cavity, resulting in abnormalities in multiple links such as ovulation, fallopian tube function, fertilization and endometrial receptivity; in addition, it may also be congenital uterine development malformations, etc. On the male side, any factors that affect spermatogenesis, maturation, excretion, capacity or fertilization can lead to male infertility.
In addition, bad living habits, such as alcoholism, smoking, drug use, etc., as well as erectile dysfunction, non-ejaculation, retrograde ejaculation, etc., may also lead to male infertility.
In addition to the physical factors of men and women, there are also age factors that can affect fertility. Whether it is a woman or a man, fertility will decrease significantly with age.
Female fertility stages according to female fertility:
20-30 years old: Best fertility period
30-40 years old: Reproductive function decline
40-50 years old: The improvement of infertility in the end of reproductive function
is closely related to the trend of late marriage and late childbirth. Both sperm and egg quality are directly related to age. For men, the number, shape and energetic proportion of sperm are crucial to the ability to successfully conceive a woman. Men have the highest sperm quality when they are 25-35 years old, and then as they age, their energy and vitality will decrease, and men's chromosomal diseases will also increase.
For women, women's fertility is closely related to the various reproductive hormones in the body and the ovarian reserve functions. Research shows that women over 35 years old will experience a cliff-like decline in the number and quality of eggs as they age. This is an irreversible process. Even if women exercise and maintain them seriously, their ovarian reserve function is constantly declining.
If you get infertile, both the couple need to have a comprehensive examination at the same time. The key is to find the cause and treat it in time.
Infertility may be the reason for the man or the woman. Under normal logic, no matter who is the reason, what the husband and wife should do is work together and face it together. In addition, assisted reproductive technology is now constantly maturing, which can help more and more people realize their fertility dreams.
