Kitchen fumes contain 74 chemicals that can cause cells to mutate, thus affecting male fertility and becoming the new evidence of “family killers”. Researchers found that the fruit flies fed with condensed oil in the kitchen exhaust hood oil cup, cell chromosome mutation rate of 0.54%, and 2.8% of the fruit fly infertility, which indicates that its reproductive system has been significantly damaged. Therefore, men are advised to cook as little as possible to avoid inhaling too much oil smoke, which can trigger male infertility. To prevent the emergence of male infertility, in addition to less cooking, but also pay attention to less tight jeans, less hot bath or sauna, etc., so as not to affect the quality of sperm, resulting in male infertility. Therefore, the man in the kitchen or become a man impotence or even infertility of the invisible killer. What are the other infertility factors that we often ignore? Often wear tight jeans According to clinical observation, under normal circumstances, the male testicular temperature will change with the body temperature, generally lower than the body temperature 3 ℃ ~ 4 ℃. Due to the tight jeans material is thicker, wear in the body breathable heat dissipation is poor, easy to make the testicular temperature close to the human body temperature, destroying the sperm survival space. In addition, jeans are more tight, wearing will oppress the male reproductive organs, affecting the normal development of testicles. Often ride a racing car Due to the special design of the racing car, the handlebar is slightly lower than the car seat, people in the use of the center of gravity will be leaning forward, waist bending increased, so that the testicles, the prostate gland close to the seat cushion. These two parts of the male by a long time after the squeeze, there will be ischemia, edema, inflammation phenomenon, affecting sperm production and prostate fluid, semen normal secretion, easily lead to infertility. Therefore, male youth should not long ride racing, this type of movement should not be more than one hour a day, but also to set on the sponge pad, to prevent the testicles and prostate long time by extrusion. Often lack of zinc and selenium diet Trace elements zinc can promote sperm motility, can prevent premature disintegration of sperm, conducive to combining with the egg, visible zinc has a significant impact on fertility. Selenium is also an indispensable micronutrient for the human body and comes almost entirely from food. Therefore, young men should not be partial to food, should pay attention to eat more zinc, selenium-containing food, such as fish, oysters, liver, soybeans, brown rice and so on. Often use high-temperature water bath Under normal circumstances, 34 ℃ ~ 35 ℃ of constant temperature environment is most suitable for the normal development of sperm, like to use more than this range of temperature bath, often also hidden “killing machine”. If you like to take a sauna bath, because the room temperature up to 70 ℃ ~ 80 ℃, very easy to destroy the sperm growth environment, or cause “dead sperm” too much and lead to infertility. Therefore, young men should be careful sauna bath, weekday bath water temperature should be controlled at 34 ℃ or so appropriate, do not break the normal growth of sperm environment. Although the man will cook is known as a good man, often for the love of a delicious meal is one in a hundred, but in order to be able to protect the tadpole, husband and wife are best to alternate cooking, reduce the risk of male infertility.
