Today’s men, the work pressure, social socializing, coupled with environmental pollution and poor living habits, etc., resulting in a gradual decline in male reproductive capacity, has to cause us to be vigilant. So how should men protect their reproductive health? First of all, you should establish a healthy concept of sex. The first thing you need to do is to have a healthy sexuality, which is the instinctive reaction of the body, the bond that increases the relationship between husband and wife, and the need to reproduce offspring. As men should establish a healthy and pure sexual concept, should be faithful to their wives, the same women should also be faithful to their husbands, to eliminate promiscuity, anal sex and other shameful sexual behavior, otherwise it is very easy to cause urogenital infection, and even infected with AIDS, resulting in less sperm, weak sperm and obstructive azoospermia, serious damage to their reproductive health. The second thing is to develop good habits of life and rest, mainly including habits of rest and diet. The actual fact is that you will need to have sufficient rest every day, not sedentary, to keep good energy and stamina, to keep enough sleep, not to stay up late, especially nowadays young people, like to stay up late playing computer games, affecting the rest, long time computer radiation, will also cause testicular function decline. Diet pay attention to the meat and vegetables, all kinds of nutrition deployment reasonable, eat more lean meat, eggs, nuts, bananas, tomatoes, honey and other foods, do not overeat, long-term spicy stimulating food. At the same time, drug abuse and frequent alcoholism and smoking can seriously affect physical and mental health, leading to a decline in the physiological function of the testicles, affecting fertility. Also forbidden to eat foods and drugs that damage reproductive function, such as cottonseed oil in cotton phenol has the effect of killing sperm, and drugs such as tretinoin can affect sperm cells to produce sperm, causing azoospermia. Once again, stay away from harmful substances and environments with radioactive radiation, and avoid long-term exposure to high temperatures. The harmful substances in the daily living environment such as paints, pesticides, industrial wastes and long-term contact with heavy metals such as lead can cause damage to the male reproductive system. x-rays and gamma rays are rays that have been identified to impair the spermatogenic function of the testicles, and a small amount of exposure can reduce the number of sperm; in recent years, it has also been found that radio waves, microwaves, ultraviolet rays, ultrasound and lasers can affect the spermatogenic function of men. Therefore, it is important to avoid unnecessary tests such as CT and films in daily life, and to avoid sitting in front of a computer to reduce radiation. The temperature of the scrotum is 2°C lower than the body temperature, which provides a good environment for the sperm production of the testicles. A high temperature will not only lead to a decrease in the sperm production function of the testicles, but also a decrease in sperm motility. So avoid long-term exposure to high temperature environments, such as frequent saunas and long-term work in boilers and other high temperatures. The last thing you need to do is to maintain a good mental state and an optimistic state of mind. Long-term depression, worry and other highly depressed state of mind, will lead to hypothalamic-pituitary-testicular gonadal axis dysfunction, affecting the normal secretion of testosterone, causing endocrine disruption, resulting in reduced fertility.
