Only the strongest, most energetic and fastest “lucky guy” is likely to be accepted by the egg. If unfortunately the number of male sperm is too small, too many deformed sperm, eggs in the “short inside the pick generals”, breeding a quality is not so high offspring, is not the result that men would like to see. 1, wear pants to pay attention to not only “prospective fathers” need to pay attention to, in the rapid development of adolescent boys can not be ignored. Don’t wear pants that are too tight, and certainly don’t wear underwear that is too tight. Tight pants, synthetic materials and high temperatures have all been shown to affect male fertility. So find a pair of loose-fitting cotton shorts! 2, pay attention to the temperature of the scrotum The optimal temperature for male testicles to make sperm is around 36°C. If this temperature is reached or exceeded, the production of spermatogonia will be inhibited, and at the same time, the vitality of sperm that have already been produced decreases. For men who often take hot baths, especially those above 40℃, the quality of sperms will decline to different degrees. When summer arrives, any increase in temperature will raise the temperature of the male scrotum, resulting in the testicles being in a high temperature state for a long time, and when the temperature of the testicles is higher than 40℃ for a long period of time, the sperm vitality will be greatly reduced. Especially men who have not had children, should pay more attention to the temperature of the scrotum. 3, don’t drink a lot of alcohol Alcohol has a strong stimulating effect on spermatogenic cells, which can damage sperm and affect the development of embryos. Long-term heavy drinking will cause male fertility to decline. It has been proved that alcohol can slow down the synthesis of testosterone and affect the normal metabolism of testosterone, resulting in hypogonadism, affecting the generation of sperm and the quality of semen. Some people in Western countries like to drink heavily, often drunk on Sundays, the night after coitus pregnant babies are called “Sunday babies”. These babies are often very weak, stunted, or even deformed or demented. Therefore, it is best to drink less or even no alcohol two or three months before the planned conception to ensure the quality of sperm. 4, not allowed to take drugs According to clinical observation, there are many drugs on the production of sperm, men’s sexual function has an adverse effect. The extent of its impact depends on a variety of factors, such as the dose of drugs, the length of time to take drugs. The sensitivity of the individual is also an important reason. At present, according to clinical research, the following types of drugs have a greater impact on men’s fertility: chemical drugs for the treatment of tumors, antihypertensive drugs, sedatives, anesthetics, androgens and estrogens, anti-gastric acid drugs, traditional Chinese medicines (tretinoin, camphor, musk, etc.). 5, environmental factors also need to pay more attention to modern society, male “tadpoles” to face the environmental problems are getting bigger and bigger, expect to change the climate to improve the sperm, I’m afraid that the human race has long been extinct. Therefore, only from the side of the smallest possible thing to do, pay attention to protect electromagnetic radiation and white pollution, to protect the sperm. For some high-risk industries, such as high temperature, high radioactivity, renovation, pesticide production and some with toxic substances such as mercury, lead, phosphorus and other toxic substances contact. If there is a lack of protective measures, the sperm count and vitality will be greatly damaged. Car exhaust, white pollution, and even common disposable lunch boxes will become the “culprit”. 6, resolutely to quit smoking Nicotine in cigarettes can kill sperm, resulting in sperm dysplasia, deformities, defective sperm accounted for a higher proportion, and can even make the chromosomes of the sperm mutation, resulting in genetic changes. If the age of smoking is too long, the number of cigarettes smoked per day is greater than one packet, will directly cause the thiocyanic acid content in the semen to increase, so as to inhibit the sperm’s mobility. It has been found that the longer the smoking age and the more cigarettes smoked, the lower the number of sperms, the higher the malformation rate of sperms, and the lower the mobility of sperms. If you are ready to have a healthy baby, it is best to quit the bad habit of smoking three to six months before you plan to conceive. 7, monitor your weight The ideal BMI for Asians is 18.5 to 22.9, but recent research by scientists has found that obesity not only causes a high incidence of cardiovascular diseases, but also has a huge negative impact on the production of sperm. The scientists analyzed that too much or too little fat can disrupt the normal production of sex hormones, which can lower sperm counts and increase the percentage of abnormal sperm. If the male body mass index control in the normal range (20-25), will be most likely to produce a large number of high-quality sperm. 8, how often is sex better In the male body, the production of primary sperm cells takes about 70 days, and then more than 20 days to reach maturity. At the same time, the sperm in the body is also in the survival of the fittest, the sperm that has been generated for too long will die out naturally and be absorbed by the body. Therefore, when preparing for childbirth, it is best for men to abstain from sex for about 3 months to ensure that the sperm in the body undergoes a major renewal and circulation. As for the frequency of sex, 1-3 times per week is considered by experts as the most ideal frequency of sex. 9, and doctor communication Semen examination has long been not the patent of infertile men, any need to procreate men can carry out a semen “physical examination”, by the professional physician to give corresponding advice, or treatment, or adjust the daily life habits. If you have doubts about your fertility and feel that your sperm is not healthy, then consult your doctor. A simple semen check and a general health check should provide some useful assistance.
