In addition to some irreversible factors, such as congenital factors, other systemic diseases and genitourinary disease factors, male infertility in many cases is caused by their own bad habits. NO.1, Smoking and drinking: The longer you smoke and the more you smoke, the lower the sperm count may be, the higher the deformity rate, and at the same time, the vitality of the sperm is also significantly reduced. This is because the chromium contained in tobacco has a strong ability to kill sperm, while nicotine and polycyclic aromatic hydrocarbons will cause sperm morphology changes. Alcohol also has a direct killing effect on sperm. If alcohol is dropped on the semen, the sperm will die immediately. Therefore, men who abuse alcohol have a higher rate of deformed sperm and dead sperm. NO.2, Improper Diet: Diet gives people enough food to eat, so that the body has energy to cope with daily consumption, but improper diet may also lead to infertility. For example, consuming too much spicy food can easily lead to congestion in a man’s genitourinary organs, so the amount of semen will be reduced and the quality will change. Eating picky food, the food lacks the two elements necessary in the production process of sperm – zinc and selenium. Without the soil and nutrients, sperm cannot be generated and mature. NO.3, Environmental Pollution: On the surface, the city appears to be prosperous and modern, but the payoff is a sharp increase in certain diseases. Urban pollution is serious, such as automobile exhaust contains a lot of harmful substances, long-term exposure to reproductive health. Urban noise is also a form of environmental pollution. Noise stimulation will affect the function of the human neuroendocrine system, so that the human endocrine disorders, resulting in male semen and sperm abnormalities. NO.4, mental tension: social competition is fierce, the spirit of long-term in a state of high tension is one of the culprits leading to male infertility. Mental tension can easily lead to endocrine disorders. As the neuroendocrine system plays an important role in the reproductive process, any interference with the neuroendocrine balance may have a negative impact on reproductive function. NO.5, pants too tight: tight, hard pants is the enemy of men. Too tight will cause constraints on the scrotum and testicles, coupled with poor breathability and poor heat dissipation, will cause the scrotum temperature to rise and reduce sperm vitality. In addition, these pants impede local blood circulation, is not conducive to venous blood return, can cause testicular blood stasis and affect the “spermatogenesis”, so it may cause infertility. NO.6, stay up late: The biological clock of human beings governs the endocrine secretion of human beings, and studies have shown that the endocrine secretion at night is exuberant. Sperm production is also the same, sperm production is mainly carried out at night, if you do not get a rest, so that the biological clock is disturbed. Long-term, endocrine disruption is likely to cause difficulties in the production of semen. NO.7, HIGH TEMPERATURE: Sperm are particularly sensitive to high temperature environment. Under normal physiological conditions and environment, the temperature of the scrotum is required to be more than 3℃ below the body temperature, and the temperature of the testes and epididymis located in the scrotum is also significantly lower than the body temperature. If you raise the temperature of the scrotum, testicles and epididymis, it may cause obstacles to the production and maturation of spermatozoa. NO.8, sedentary: after sitting for a long time, the perineum is oppressed, the perineum has testicles, the prostate has seminal vesicles, especially sitting on the soft sofa, the local perineum circulation is blocked, the local temperature rises, coupled with the compression, so that these organs are congested, it is easy to induce inflammation, such as prostatitis.
