Many couples who have been married for several years have not yet conceived, on the one hand, because of the expectation of the in-laws to hold grandchildren, especially the daughter-in-law living with the in-laws is the most stressful; on the other hand, colleagues in the office compare each other, talk about the embarrassment of the family and children, etc., which invariably increases the difficulty of conception. The reason is 2, personal habits and living environment pollution Human reproduction experts recently compared the quality of male semen 50 years ago with the semen of men today, and found that the amount of male semen and sperm concentration has dropped by more than half in 50 years. After research and analysis, it was concluded that the main reasons for this change are the following two: on the one hand, due to human habits, such as smoking, pharmaceuticals, washing sanna or wearing tight pants, etc., resulting in a decrease in the ability of the testicles to produce sperm; on the other hand, due to the pollution of the living environment, such as the extensive use of pesticides, urban cars, factories and other emissions of toxic volatile heavy metals or waste. Due to the rapid progress of industry and technology, toxic substances that may affect human fertility will also affect human beings at a rapid pace. Many environmental toxins not only cause abnormal sperm function in men, but also affect women’s ovulation skills, sperm and egg binding ability, as well as the fertilization of the egg or cause an increase in early pregnancy and miscarriage. 3, the openness of sexual life led to an increase in STDs In recent years, due to the significant opening of the concept of sex, the increase in unmarried men and women sex, coupled with the ease of access to oral contraceptives, some unhealthy sexual behavior led to an increase in the transmission rate of STDs, STDs in both men and women will cause obstacles to the ability to conceive. Common STDs, such as gonorrhea and syphilis, can damage the fallopian tubes of women and impair the ability of men to produce sperm. In 1992, the World Health Organization estimated the impact of human sexuality on fertility and estimated that approximately 100 million men and women have sexual intercourse every day on earth, and that 910,000 women conceive as a result. Of those women who conceive, about 300,000 choose to have an abortion. And of those 100 million or so sexual acts, another 150,000 of them result in a daily payload of STD cases. Many unmarried pregnant women who undergo abortion fail to seek the care of an experienced obstetrician and eugenicist, resulting in sequelae of uterine cavity, tubal or pelvic lesions, and consequently infertility. If patients with STDs are not diagnosed early and treated appropriately and completely, the factor of future infertility is often planted, thus showing the importance of healthy sexual behavior. The best age for human fertility is around twenty-four to twenty-six years old, and as soon as it exceeds thirty years old, the fertility of both men and women decreases significantly. During the time of our parents and even grandparents, most of them got married and had children in their twenties, and the most important responsibility of women at that time was to bear and raise children and help their husbands. Since they were able to capture the peak of human fertility, they were less likely to suffer from infertility. The current form of society, on the other hand, is mostly small families, and the vast majority of them are two-income families, where couples mostly want to have children only after their economic situation has stabilized. As a result, many women have to spend their savings from hard work in their twenties and thirties on infertility treatment, which is an unforeseen regret.
