Avoid smoking (smoking has a negative impact on fertility: it can increase DNA damage; increase aneuploid sperm; may lead to testicular atrophy; semen volume, concentration, vigor and morphology and other indicators are abnormal. (Some foreign IVF centers require smoking cessation for more than 3 months); you can drink less alcohol (the data show that drinking alcohol in less than moderate amounts has little effect on fertility, but I personally recommend abstaining from it because the amount of alcohol is difficult to control for a variety of reasons, plus the individual’s sensitivity to alcohol is different); stay away from radiation (radiation is inversely proportional to the cube of the distance, and when the distance is increased by a factor of 1, the radiation is attenuated by 1/8); stay away from all kinds of harmful Chemical substances; do not take a sauna, do not wear tight underwear for a long time (sauna or wear tight underwear for a long time will make the local temperature rise, inhibit spermatogenesis, there is information that shows that, such as fever more than 39 degrees, sensitive men may inhibit the spermatogenesis for more than half a year); you can eat more fish, the motherland of the medical Mani Huang’s art that the fishermen have more children, may be the swim bladder of the fish have the role of spermatogenesis; weight loss (human adipose tissue contains aromatase, aromatase makes the body fat) Aromatase, aromatase converts testosterone to estradiol, which lowers serum testosterone levels; at the same time, estradiol increases, which has a strong negative feedback effect, leading to a decrease in FSH and affecting spermatogenesis); exercise (the latest research shows that exercise can help increase testosterone levels and sperm quality); avoid high fever (a small-scale study in foreign countries has shown that high temperature affects the sperm’s DNA integrity, and some IVF centers recommend that it is best to avoid high fever in the first week of pregnancy. Some IVF centers suggest that it is best to perform IVF/ICSI 2 months after high fever). In recent years, more and more basic and clinical research suggests that environmental pollutants endanger male fertility, mainly manifested in the decline of sperm density and semen quality, etc. In addition, environmental pollutants also cause malformations of the male reproductive system and increased incidence of tumors. These environmental pollutants are also known as endocrine disruptors (EDs) because of their ability to interfere with the human endocrine system. The main endocrine disruptors (EDs) are Atrazine (Atrazine, which is an insecticide), Octylphenol, Methyl DDT, Bisphenol A, Tetra-Oxydiphenyl Dioxane, and others. You also need to take rest without interfering with your work, don’t stay up late, etc. Laozi in the Tao Te Ching in the important fine thought is no for and no thought, is to be in accordance with heaven and man, and the laws of nature in line with the rest when the rest of the rest of the time. A good state of mind is important for infertility diagnosis and treatment, especially for women, if the state of mind is not good, it will affect the reproductive endocrine, which may also be an important factor affecting the success rate. Lao Tzu said in the “Virtue Classic” that “Restlessness is better than congestion, quietness is better than heat, and tranquility is considered to be the right thing in the world.” This all points to the importance of maintaining a good state of mind when seeing a doctor, especially important for female patients with infertility. The following is a partial summary of substances that damage the health of the reproductive system, for reference only, and welcome exchanges and additions.
