Male infertility not only causes men to be unable to conceive life, but also affects their health with serious consequences; some studies have shown that male infertility will also increase the risk of heart disease and diabetes. Through the study, researchers said that male individuals diagnosed with infertility are at higher risk for other common diseases, such as diabetes, ischemic heart disease, alcohol and substance abuse, compared to men of normal reproductive age. Studies have shown that the factors that trigger problems in the male reproductive system may also affect the body’s physiological system; here it is encouraged that men, especially those experiencing reproductive difficulties, should be promptly examined, and having a sperm count and infertility test can help predict male fertility, which is of course crucial for eugenics. So, what should we do to prevent male infertility? The company’s main goal is to provide the best possible service to its customers. Under normal circumstances the testicular temperature should be 1°C to 2°C lower than the body temperature. The temperature of the bath should not be too high under normal circumstances sperm must be in 34 ℃ ~ 35 ℃ constant temperature environment in order to develop normally; bath water temperature is too high often hidden “killing machine”, such as sauna room temperature can be as high as 70 ℃ ~ 80 ℃, more than double the normal bathroom temperature, very unfavorable to the growth of sperm, or cause The “dead sperm” is too much and leads to infertility. From the causes of male infertility was learned that part of the men is precisely because the testicular temperature is 2 to 3 degrees higher than normal, resulting in sperm can not be viable. The young man should be careful to take a sauna, usually, the bath water temperature should also be in about 34 ℃ is appropriate. Therefore, young men should not ride a race car for a long time, should not exceed one hour a day, to protect the perineum of the cushion application sponge cover. The diet pay attention to the necessary elements to supplement the trace element zinc can increase the mobility of sperm, can prevent premature disintegration of sperm, and facilitate the combination with the egg, it can be seen that zinc has a significant impact on fertility. Selenium is also an indispensable trace element for the human body, and comes almost entirely from food. Researchers observed 1000 cases of male infertility and found that 37 people had insufficient selenium in their semen. Therefore, young men should not be partial food, should pay attention to eat more zinc, selenium food, such as fish, oysters, liver, soybeans, brown rice, etc.. The fact that the man’s sperm production is not sufficient to meet the requirements for conception, and that the woman’s endocrine function is not regulated, affects the development of follicles. All these are not conducive to conception. The couple should cooperate with each other to lead a moderate, effective and harmonious sex life. The treatment of infertility should not be impatient, the couple should work closely together, insist on determining the wife’s ovulation period, and increase the number of intercourse before and after ovulation to increase the chances of conception.
