It is very easy for men to have unclean sex to cause orchitis. During sex, the male penis comes into direct contact with the female vagina, and if there are bacteria in the female vagina, they will infect the penis directly through sex, thus inducing orchitis. It is important for men to pay attention to hygiene and safety when having sex. How does orchitis cause male infertility? If the epididymitis is caused by pathogens such as gonococcus and mycobacterium tuberculosis, the inflammatory reaction will not only damage the sperm, but also easily cause the narrowing or blockage of the lumen of the epididymis, resulting in obstructive azoospermia. 2. Formation of anti-sperm antibodies Testicular inflammation is also an important cause of sperm antibodies. When inflammation occurs in the testes, immune cells and humoral immune substances enter the inflamed epididymal ducts and produce immune reactions against pathogens, forming antibodies that will affect the forward movement of sperm. When the epididymis is infected, some pathogens can directly harm the sperm in the epididymal duct, inhibit sperm motility or cause sperm agglutination to reduce its motility; some pathogens are adsorbed on the surface of sperm to reduce its motility or even lose it. 4, reduce the vitality of sperm White blood cells, macrophages and other body guards in the elimination of pathogens, may not be good or bad, accidental injury or accidental killing of sperm; inflammatory reaction to produce a large number of metabolites, will also poison sperm, or change the sperm survival environment, so that sperm mobility decreased, dead sperm increased, resulting in a rise in the rate of deformed sperm, sperm count decreased, etc., these can lead to male infertility. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. 2, sexual function decline caused by male sexual function decline, or even complete loss, so when the testicular infection to go to the hospital in time for examination and treatment, and strive to minimize the harm.
