The testes can produce sperm well at a temperature of 2°C to 4°C below the abdominal cavity. Sitting for a long time will affect the heat dissipation of the scrotum, leading to an increase in the temperature of the scrotum, which in turn affects the sperm-producing ability of the testes. And staying in an environment of electronic radiation such as computers and TV for a long time can affect the testes’ ability to produce sperm. At present, although the relationship between prostatitis and fertility has not been fully elucidated, when prostatitis occurs, changes in the secretion function of prostatic fluid can occur, thus affecting the amount of semen and its composition, and interfering with the survival and activity of spermatozoa. The decrease of enzyme activity in prostate fluid will increase semen viscosity and prolong the liquefaction time of sperm. The presence of inflammation can also lower the pH of semen and produce anti-sperm antibodies, leading to the death of sperm. The IT industry men sedentary so that the prostate is compressed, prostate fluid drainage is not smooth, the formation of depression; hold urine so that the urethral pressure increases, easy to make the urine back into the prostate; drinking less water so that the urine is concentrated, the storage of urine time growth, easy to infection, these are all the triggering factors of prostatitis. At the same time, men engaged in the IT industry is often the first to establish a career after the family, the age of childbearing postponed to more than 30 years later. According to research, there is a natural decline in male fertility after the age of 35, which makes these men join the ranks of the infertile. In order to prevent the occurrence of infertility, men engaged in the IT industry should pay attention to self-protection in their daily lives, do not abuse alcohol, eat less spicy food, avoid prolonged cycling and sedentary, have a regular sex life, pay attention to local warmth, drink more water, less hold urine, minimize contact with electronic products, and it is best to start sowing the seeds of love in the appropriate age of fertility.
