A hot bath in winter, not only to drive away the cold, but also to relax the body and mind, is the most enjoyable moment for people in winter. However, many men will choose a very high temperature when bathing, which will not only burn the skin care, but also may cause infertility to men. So, how high is the temperature of the male bath to be appropriate? Why is the bathing temperature too high can lead to male infertility? The bath temperature is too high, leading to male infertility Under normal circumstances, sperm must be in 34 ℃ ~ 35 ℃ constant temperature environment in order to normal development, bathing water temperature is too high often hidden “killing machine”. Sauna bath room temperature can be as high as 70 ℃ ~ 80 ℃, more than double the normal bathroom temperature, very unfavorable to the growth of sperm, or cause “dead sperm” too much and cause infertility. The medical doctor learned from the causes of male infertility, part of the man is precisely because the testicular temperature is 2 to 3 degrees higher than normal, sperm can not be viable. The young people should be careful to take sauna baths, usually, the water temperature of the bath should also be in about 34 ℃ is appropriate. The contraction of the scrotum is to regulate the temperature of the testicles below the body temperature of about 2 degrees, the testicles only below the body temperature of about 2 degrees to facilitate the secretion of testosterone to the best state. Testosterone is an important substance that promotes sperm production. Now the popular tight-fitting men’s underwear, generally in front of the design are double, the scrotum and penis wrapped together for a long time, resulting in the crotch long-term in a hot and humid environment, becoming a breeding ground for viruses and bacteria. The long term high temperature and humidity of the crotch is a potential risk for common male diseases such as prostatitis, varicocele, vesiculitis and scrotal eczema. Prostatitis, varicocele and vesiculitis are common diseases of male infertility. So experts recommend wearing more breathable, heat dissipation isolated good scrotal bag underwear, long-term keep the crotch dry and breathable heat dissipation. So, how to prevent male infertility in winter? 1, pay attention to observation More observation of testicles, such as different from the usual changes: swelling, hardening, bumpy, pain, etc., must be timely diagnosis and treatment, more to master a certain amount of sexual knowledge, understanding of male physiological characteristics and health care knowledge, if the testicles are found to have different from the usual changes such as must be timely medical treatment to prevent male infertility. 2, dietary attention Do not lack zinc less selenium, the trace element zinc can promote sperm motility, can prevent premature disintegration of sperm, facilitate the combination with the egg, it can be seen that zinc has a significant impact on fertility. Selenium is also an indispensable trace element of the human body, almost all from food. 3, do not wear tight jeans, do not shower too high temperature Men wearing tight jeans will seriously affect the normal development of testicles, because not heat dissipation so lead to unfavorable sperm survival. Do not ride a race car for a long time, because the height of the racing handlebar is lower than the seat, making the testicles of the perineum, the prostate gland close to the cushion, which will lead to testicular ischemia, edema, inflammation after squeezing.
