Research shows that 74 kinds of chemical substances in kitchen lampblack mutate cells and become sterile, becoming new evidence of family killer. They found that the mutation rate of cell chromosome of Drosophila melanogaster that drained condensate from the kitchen oil cup was 0.54%, and 2.8% of Drosophila melanogaster was sterile, indicating that the reproductive system was significantly damaged.
Other behaviors of male content:
Wear tight jeans, male content
Andrologists and urologists believe that tight-fitting jeans not only oppress male reproductive organs, but also affect the normal development of testicles. They are not breathable, not heat dissipation, and are not conducive to sperm survival. Under normal circumstances, testicular temperature is 3 ℃~4 ℃ lower than body temperature.
Riding a racing car for a long time can easily lead to impotence in men
The height of the handlebar of the racing car is lower than the seat, the center of gravity tilts forward, the curvature of the waist increases, and the testicles and prostate of the perineum cling to the cushion. After being squeezed for a long time, it will cause ischemia, edema and inflammation, affecting the production of sperm and the normal secretion of prostate fluid and semen, resulting in infertility. Therefore, young men should not ride a racing car for a long time, and should not exceed 1 hour a day. Sponge covers should be used to protect the perineum cushion.
Too high bath temperature, male impotence
Under normal circumstances, sperm must develop normally in a constant temperature environment of 34 ℃~35 ℃. When entering the bath, the water temperature is too high, which often leads to dark killing. The room temperature in the sauna reaches 70 ℃~80 ℃, which is more than twice the temperature in the ordinary bathroom, which is not conducive to the growth of sperm, or too many dead sperm are sterile. Medical experts learned from the causes of male infertility that the temperature of some male testes is 2 to 3 degrees higher than that of ordinary people, and sperm cannot survive. Therefore, young people should be careful to take a sauna, and the temperature of the bath should also be around 34 ℃.
Zinc deficiency and selenium deficiency diet lead to male impotence
The trace element zinc can promote sperm motility, prevent sperm premature disintegration, and facilitate the combination with eggs. It can be seen that zinc has a significant impact on fertility. Selenium is also an indispensable trace element for human body, almost all of which comes from food. Japanese medical researchers observed 1000 cases of sexual infertility and found that the selenium content in 37 semen was insufficient. Therefore, young men should not be partial to food. They should pay more attention to eating foods containing zinc and selenium, such as fish, oysters, liver, soybeans, rough rice, etc.
