People who have a bathtub at home always like to take a warm, hot bath on a cold winter night. Although the spirit and body are extremely relaxed, but if the bath time is too long, the water temperature is too hot, which is tantamount to “murder” for the sperm. The appropriate temperature for sperm production and survival is 1 to 2 degrees Celsius below body temperature, and winter bath for a long time in a high temperature environment, will make the sperm survival environment is destroyed, while the spermatogenic epithelium is damaged.” The spermatogenic epithelium of the testicles is specialized in producing sperm, once it is destroyed, the quantity, quality, density and motility of sperm will be reduced and there will be difficulties in generating new sperm again. This will lead to a reduced chance of conception and an increased rate of infant malformations. Similar to this, there are often prolonged sauna, hot springs, sleeping on electric blankets, etc., which can cause a decrease in sperm production due to high temperatures. Therefore, if you are a man who loves “high temperature”, it is best to reduce the time spent in a high-temperature environment, the habit of taking a shower instead of a bath. The diet hazards can’t be avoided In the diet, the greatest impact on male reproductive function is tobacco and alcohol. According to experts, the sperm count of long-term smokers and excessive drinkers is significantly lower than that of non-smokers and non-drinkers, and the morphological abnormality rate of sperm is also significantly higher. Therefore, in the first few months of preparing for pregnancy, the father-to-be should completely quit smoking and drinking to ensure successful conception and the health of the child. However, while quitting smoking and drinking is usually understood by everyone, there are some foods that many people don’t think about. For example, raw cottonseed oil, lei gong teng (Chinese herbal medicine) and compound tonics such as xuan ginseng, asparagus, water containing stone, cypress and genistein can affect spermatogenic functions and reduce sperm vitality. Soy foods, which people perceive as healthy and nutritious, are rich in phytoestrogens, which, when consumed in excess, can cause endocrine disruption in the body and may reduce the number and vitality of sperm. For men who have fertility requirements, when consuming legumes must be in moderation. The next environment should be “loose” Nowadays, young people catching up with the trend, even the underwear should be worn tight enough to be fashionable. However, the curve is exposed at the same time, will also make the “penis” times bound. The tight pants can make the testicles in the environment temperature rise, affecting the differentiation of sperm cells, is not conducive to the generation of sperm, on the other hand, will affect the blood circulation of the scrotum, leading to a decline in male fertility”, should try to avoid wearing, and choose loose underwear. Even so, to keep the lower body environment breathable and comfortable, but also to prevent long-term sitting inactivity. According to the report, many drivers are sterile patients, this is because often sitting for a long time, the prostate gland is under pressure, blood supply is reduced, poor circulation, local resistance is reduced, easy to induce prostatitis. The number of sperm is reduced by mental tension As the pace of life and work accelerates, people have less and less time to exercise, and their body resistance is getting worse. Especially for men, life is more stressful, long-term excessive tension, the body is in a state of emergency, the resulting stress hormones affect the hypothalamus-pituitary-testicular gonadal axis, can make the number of sperm significantly decreased. Therefore, adjusting your mind, correcting your attitude towards work or life, and establishing a correct outlook on life is beneficial to keep away from the “sub-health” state.
