Nowadays there are more and more families with infertility. At the same time people seek solutions, in life we should also want to avoid the possibility of causing infertility, so what places need our attention? 1, wearing clothes Clothes fit, the temperature is appropriate, conducive to spermatogenesis, otherwise, the testicles, spermatogenesis has an impact. Such as men often wear too tight pants, testicles and scrotum can be tightly attached to the body, increasing the local temperature of the testicles, hindering the development and growth of spermatozoa. Tight pants will also tightly wrapped scrotum, so that the scrotal skin is good at heat dissipation of the ability not to play, and thus the local temperature of the testicles will also rise. In addition, tight pants will limit and impede blood circulation in the scrotum, especially to prevent venous blood return, which is very unfavorable to sperm production, and will affect the hardness and durability of penile erection over time. 2, the diet has a good nutritional status, the body can produce a sufficient number of, full of vitality, normal robust sperm to. If the nutrition is poor, the sperm produced may be less in number, poor vitality, high deformity rate. If nutrition is very poor, it can also lead to infertility. Long-term heavy drinking is again one of the major factors leading to infertility. Recent studies have shown that alcoholism not only leads to a reduction in the function of the reproductive glands and inhibits sperm formation, but can also cause 7% of sperm to be underdeveloped or inactivated, and cause chromosomal abnormalities in the sperm, which can lead to fetal malformations or underdevelopment. In addition, it has been reported that long-term consumption of crude cottonseed oil can also lead to male infertility, because crude cottonseed oil contains a large amount of cotton-phenol, which affects the evolution of germ cells in the testes into spermatozoa. Taking certain anti-cancer, anti-epileptic, anti-hypertensive and sedative drugs, on the growth, development and sexual function of spermatozoa also have indirect or direct impact. 3, residence Many infertile men are caused by environmental factors, such as high-temperature workers, long-term exposure to radiation or certain harmful substances, etc., can make the spermatogenic function of the testes affected, and spermatogenesis is impaired, thus causing infertility in men. 4, traveling Moderate running can not only improve the mood of life, but also play a strong role in the organs of the urinary system. But don’t overdo it, or it can also reduce libido. According to Canada’s University of Alberta research that men often long-distance walking, will make the libido sharply reduced, walking 65 kilometers a week men, will make the body’s hormone reduction, which produces fatigue, prompted by reduced libido. Another example is long-distance cycling, which also hinders sperm production and reduces sperm activity. But after physical recovery, libido will be restored, so men engaged in long walks, long-distance cycling labor may not have to carry this ideological prison. As long as the fertility stage is not overactive, fertility will not be affected.
