1992 The World Health Organization survey showed that among infertile couples, female infertility accounted for 37%, male infertility accounted for 8%, the two factors accounted for 35%, and other factors accounted for 20%. Fertility is one of human instincts, but many modern women are healthy, but they just can't conceive when they are ready to have children. What is the reason? In addition to pathological factors, infertility is also related to age, mental factors and unhealthy lifestyle.
Old age. Some couples, especially women, delay their childbearing age for various reasons, especially after 35, which will bring many unfavorable factors. Because with the increase of age, egg quality and ovarian function decline, and the probability of infertility will also increase. Studies have shown that the fertility of ordinary women begins to decline after the age of 30. The fertility rate of women aged 35-39 is 25% lower than that of women aged 20-29, and that of women aged 40-45 is 95% lower. Moreover, the probability of birth defects in elderly women has greatly increased, and the incidence of pregnancy complications has also increased.
Multiple induced abortions lead to post-abortion complications. Induced abortion can cause pelvic inflammatory disease, which in turn affects the fallopian tubes. Once the fallopian tube is inflamed and blocked, infertility may occur. Not only that, repeated induced abortion will make the uterine wall thinner. When pregnant, the embryo is like a seed, but the thin uterine wall is barren soil, and the placenta can't grow well, even if it is pregnant, it is difficult to succeed. It can be said that the number of abortions is directly proportional to the future risks.
Some bad habits. For example, smoking and drinking, improper diet, overweight and thinness, and exposure to some bad factors at work can all cause infertility. For some special occupations, such as long-distance runners and professional dancers, high-intensity physical training and strenuous exercise often lead to ovulation and amenorrhea, as well as infertility.
Mental factors are also an aspect of infertility. For example, clinically, we can see that some female patients are anxious to get pregnant, their regular menstruation has become abnormal, and the man's extreme mental stress leads to abnormal sexual intercourse. In addition, if women are often in a state of high pressure, the cerebral cortex will not be able to secrete hormones normally and inhibit the normal ovulation function of ovaries, thus affecting pregnancy.
