The causes of male infertility generally include the following aspects:
(1 )Sperm deficiency. The testicles are the place where sperm are produced. If the physiological functions of the testicles malfunction, sperm production (quantity and quality) will be affected. Common causes include: endocrine dysfunction of the pituitary gland, adrenal glands, and testicles themselves; congenital malformation of the testicles or testicular atrophy caused by cryptorchidism and mumps; frequent exposure to nuclear elements, X-rays and other radioactive elements that damage the testicles; spermatic cord Varicose veins. Blockage of testicular blood circulation causes spermatogenesis disorders, etc. In addition, lack of vitamin A, calcium, zinc, phosphorus and other substances are also causes of abnormal sperm production.
(2) The vas deferens tube is blocked. Sperm produced by the testicles have to travel a long way through the epididymis, vas deferens, ejaculatory duct and urethra before they can leave the man’s reproductive tract and combine with the egg. If any of these sperm transport channels is blocked, the sperm will not be able to pass smoothly. It will cause infertility. Common diseases are tuberculosis of the epididymis and vas deferens and gonococcal infection (gonococcal infection).
A research team from the National University of Singapore found thatmen who work in engineering, financial analysis, corporate and computer management and teaching are more likely to be infertile than men in other occupations. To investigate whether men\’s occupation affects their fertility, the research team surveyed 640 men whose spouses were unable to conceive or were undergoing infertility treatment. They also screened 218 men whose causes of infertility could not be identified. men and compared these men with 227 men whose wives were currently pregnant.
The comparison was conducted in the form of a questionnaire. The men needed to answer questions including their living habits, such as whether they smoked, their occupations, whether they worked in chemistry or radioactivity, etc. They also received sperm analysis. test. Men who work as teachers are seven times more likely to be infertile than ordinary men, men who are engaged in financial analysis are five times more likely to be infertile, and men who are engaged in engineering technology and company computer management are three times more likely to be infertile than ordinary men. . Men who work in service or clerical jobs have the lowest rates of infertility. In addition, the survey also found that men who smoke regularly are more likely to suffer from infertility.The probability is three times that of non-smoking men.
It can be seen from the above survey thatpsychological stress, higher work requirements and possible electromagnetic field working environment are the main factors leading to male infertility.
