Six things men are afraid of! These are enough to destroy the tough guy

The growth process of sperm requires low temperature, otherwise the sperm will die. To maintain this physiological state, when the temperature is too high, the heat dissipation area is expanded, and when it is cold, it will wrinkle to reduce the heat dissipation area, thereby keeping the temperature of the scrotum lower than that of the abdominal cavity.

Men's sperm is actually delicate in nature and easily harmed by various "enemies", so we must not take it lightly in daily life.

Afraid of being hungry

Sperm growth requires nutrients. Some men have a monotonous diet, are partial to certain foods, are picky eaters, and do not like to eat animal foods (such as meat, eggs, fish and dairy products). Over time, this can cause a decrease in the zinc content in the body. The trace element zinc is known as the "factor of marital harmony". It can reduce the number of sperm by 30% to 40%, and even cause a person to lose his fertility.

Smoking and excessive drinking are the enemies of sperm. Some men's bodies are quite sensitive to the toxins in cigarettes, and the nicotine in cigarettes can kill sperm. An Australian chemist said that once men quit smoking, the sexual excitement in their blood will increase. A Hungarian medical doctor claimed that the number of sperm in the semen of smokers is less than that of non-smokers, but the number of abnormal sperm is more. If an adult male smokes 30 cigarettes a day, the survival rate of sperm is only 40%, and the sperm deformity rate increases. It can be seen that long-term and heavy smoking is one of the important factors leading to infertility. Alcoholism can not only lead to reduced gonadal function, but also cause chromosomal abnormalities in sperm, thus causing fetal malformations or developmental abnormalities. Therefore, teenagers should develop the habit of staying away from tobacco and alcohol. As an adult, even if you don’t quit smoking or drinking, you should be careful not to overdo it.

Second, fear of "heat"

The growth process of sperm requires low temperature, otherwise the sperm will die. To maintain this physiological state, when the temperature is too high, the heat dissipation area is expanded, and when it is cold, it will wrinkle to reduce the heat dissipation area, thereby keeping the temperature of the scrotum lower than that of the abdominal cavity. If a man has a hobby of taking hot baths, it may reduce the number of sperm and lead to infertility.

The third fear is “frequency”

If you masturbate too much or have sex too early, it can lead to impotence and reduce the amount of sperm produced each time.

Fear of "drugs" and "radiation"

Frequent use of sedatives, anti-tumor drugs, mylerin, furan drugs, and hormone drugs in chemical drugs can cause sperm growth disorders, sperm chromosome damage and breakage; large amounts of radiation exposure can also cause sperm chromosome abnormalities. Therefore, men in their reproductive years should try to avoid long-term and excessive exposure to such harmful substances and not abuse drugs at will.

The fifth fear is "worry"

If you are depressed and your emotions are unstable for a long time, it can directly affect the functions of the nervous system and endocrine system, causing disorder in the testicular spermatogenesis function, and in severe cases it can lead to infertility after marriage.
