Before "making people", men need to quit smoking and prohibit excessive drinking
Men should quit smoking, refrain from excessive drinking, and refrain from taking drugs indiscriminately. Germ cells are very sensitive to the toxins in tobacco and alcohol, which can affect the quantity and quality of sperm, and even lead to infertility or the production of abnormal babies. Nicotine has the effect of reducing sexual hormone secretion and killing sperm. Men who smoke 30 cigarettes a day have a sperm survival rate of only 49%. Long-term or heavy alcohol consumption can lead to chronic or acute alcoholism, leading to 70% of sperm dysplasia or loss of vitality. Many drugs are likely to be chromosomal teratogens. Therefore, three months before "making a person," men should quit smoking and drinking, and should not take drugs at will. Because the maturation cycle of sperm is approximately three months, the development of sperm undergoes a process of primary spermatocyte → secondary spermatocyte → spermatocyte → sperm, during which the most feared intake of substances harmful to sperm is.
How to make sperm more "refined"
Having fertile soil is only one of the conditions, and good seeds are necessary to ensure good seedlings.
The same goes for pregnancy. If you want to have a healthy and intelligent child, prospective fathers must first learn to maintain their "refined" strength. "Because the quantity and quality of sperm is one of the key factors for eugenics, men generally have a wide range of social and business activities, and it is inevitable that they often become infected with tobacco and alcohol, or stay up late. It is important to know that tobacco and alcohol, as well as irregular work and rest, are both killers of sperm.".
There is also a problem with sperm that exists in the testicles and has a survival time of more than two months. Without ejaculation, the constantly accumulating sperm will age and be absorbed by the body again. Therefore, if preparing to conceive, a husband should expel the aged sperm one week before his wife ovulates, so as to ensure that the most viable sperm can swim towards the uterus and merge with the egg.
