A similar study was done abroad on 189 healthy men between the ages of 18 and 22 years old to conduct a survey on television viewing habits and exercise habits. The results found that men who watch TV for at least 20 hours a week have a 44% reduction in sperm count compared to men who do not watch TV. Experts say that if you stay in a sedentary position for a long time, the temperature of the scrotum will rise and the testicles will be pathologically damaged, resulting in a decrease in the sperm production capacity of the testicles. At the same time, sedentary tend to make the spermatic vein blood flow back poorly, varicose veins, may affect male fertility. Because of the stagnant blood in the spermatic vein, the local temperature of the testicles will rise, affecting the local environment of sperm production, producing oxidative stress effects and affecting sperm quality and quantity. This will even affect testicular function in the long term, leading to male infertility. Second, the bath temperature is too high under normal circumstances sperm must be in 34 ℃ ~ 35 ℃ constant temperature environment in order to normal development, bath water temperature is too high often hidden “killing machine”. Such as sauna when the 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 “dead sperm” too much and infertility. The medical doctor learned from the causes of male infertility, part of the man is precisely because the testicular temperature is 2 to 3 degrees higher than normal, 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 ℃ appropriate. Under normal circumstances, the testicular temperature is 3°C to 4°C lower than the body temperature. Is it infertility? Be sure to get a good examination first In addition to the above-mentioned small details that can increase the chances of male infertility, there are many reasons that lead to infertility, so it is important to understand the routine examination items for male infertility. The diagnosis of male infertility mainly consists of medical history, physical examination and laboratory tests, other tests, etc.: 1. Medical history taking: it is important to take a correct medical history, the doctor should be responsible and keep it confidential for the patient; the patient should also cooperate vividly and reflect the relevant situation truthfully; 2. Physical examination: it includes a whole body and reproductive organ examination. The focus is on the examination of reproductive organs; 3. Laboratory examination: semen examination is the most common examination item for the diagnosis of male infertility. The semen examination includes routine analysis of semen, morphological analysis of sperm, sperm membrane surface antibodies, biochemical examination of seminal plasma, etc. The second should exclude the detection of inflammatory diseases of the reproductive tract, such as mycoplasma, chlamydia detection, etc. 4, other examinations: scrotal ultrasound, endocrine examination, chromosome detection, testicular biopsy, etc. In order to prevent infertility, men should learn four moves to improve sperm health In the face of environmental pollution and bad habits, how can men raise high-quality “tadpoles”? In fact, life more attention to some small, diet focus, sperm quality can really improve. A, eliminate the bad habits of life As people’s work is indeed more intense, more social, but some bad habits of life will lead to a decline in sperm vitality, such as irregular life, diet spicy, sedentary, etc.. Therefore, attention should be paid to not addicted to alcohol, spicy, do not wear or less wear jeans, do not wash or less sauna bath, avoid high temperature and radiation work environment, etc.. Second, prevent body obesity male too obese, will make the body androgen reduction, estrogen relative increase, thus hindering sperm generation, affect sperm quality. In addition, too obese can also induce hypertension, diabetes, these diseases may trigger sexual dysfunction. So, for the sake of your angel baby, the unexpecting fathers should also control the mouth, open legs ah! Therefore, men should eat more zinc-containing foods. The main plant foods that are rich in zinc are beans, peanuts, millet, radish, cabbage; animal foods are best in oysters, followed by beef, chicken liver, eggs, lamb chops, pork. Fourth, exercise and sunlight is indispensable Men had better change the “car instead of walking”, go out to take the elevator habit, more exercise, which has been known to people. Sunlight will also stimulate male sperm vitality, because vitamin D may play a decisive role in the process of semen production, and the lack of it may lead to infertility.
