Patient's question:
I have a friend who has not been able to get pregnant for several years. He doesn't know if it's a male or female issue, and he wants to find a hospital to check it out.Doctor's answer:
The main causes of male infertility can be summarized into 5 categories:① Sexual dysfunction, including impotence, premature ejaculation, nocturnal emission, and anejaculation. Anejaculation accounts for 32.4% of male infertility cases.
② Abnormal semen quality, including oligospermia, azoospermia, necrospermia, asthenospermia, polyzoospermia, hyposemenia, and semen agglutination. Oligospermia accounts for 15.4% of male infertility cases.
③ Varicocele, which accounts for 12% of male infertility cases.
④ Immunological factors: Refers to the presence of antisperm antibodies in male serum or seminal plasma, leading to autoimmune sperm reactions and resulting in immunological infertility.
⑤ Reproductive tract infections, congenital abnormalities, systemic diseases, and unexplained causes of infertility.
What external factors can cause infertility?
Many modern factors can affect fertility:
① Environmental pollution: In addition to water, air, and food pollution affecting reproductive function, there are also electrical, magnetic, radiation, and noise pollution, as well as microwave, infrared, ultraviolet, ultrasonic, X-ray, and gamma-ray pollution.
② Temperature and heat can inhibit the spermatogenesis process: For example, long-term wearing tight clothing can impair the temperature-regulating function of the scrotum, affecting spermatogenesis.
③ Toxic and harmful substances: Such as heavy metals like aluminum, cobalt, and lead, as well as gossypol, insecticides, herbicides, and preservatives, can all damage the testicular spermatogenesis function.
④ Malnutrition, deficiencies in trace elements and vitamins can all lead to infertility.
