Male infertility is generally treated as a disease in medicine. In fact, recent medical research has shown that rather than being a common male condition, it is better to treat it as a sign of some disease. The reason is that clinically, for most infertile men, as long as the underlying disease is cured, the sign of infertility will be gone. So, what diseases can be detected from this sign of male infertility? Cryptorchidism The medical term for any abnormal testicular position or failure to descend into the scrotum is cryptorchidism. According to statistics, abnormal testicular position is found in about 10% of newborns and 2% of young children. In the past, it was thought that only bilateral cryptorchidism would affect fertility, but in recent years, it has been found that the infertility rate of unilateral cryptorchidism is about 67% or more. Although it is reasonable to say that a unilateral testicle can completely compensate for the role of two testicles, in reality, unilateral cryptorchidism produces some antibodies against sperm due to the adverse effects of temperature, thus depriving the normal testicle on the opposite side of the role of sperm production. This kind of infertility, called “blood testicular disorder”, also has more chances of testicular tumor than normal men, and, due to the misconceptions of traditional concepts, it has not been paid attention to so far. Chlamydia trachomatis infection Perhaps the conclusion of the study that trachoma causes male infertility will surprise you. In fact, Chlamydia trachomatis infection can cause urethritis, vasovaginitis and epididymitis in men as well as sexual dysfunction due to Chlamydia trachomatis. More so, sperm motility is reduced due to inflammation of the vas deferens, which in turn causes infertility. Mycoplasma infections According to research, a significant number of male infertility is related to various viral and bacterial infections. For example, mumps virus, gonococcus, E. coli, Staphylococcus aureus, Staphylococcus albus infections and mycoplasma infections, which are intermediate between viruses and germs. Among them, foreign scholars found that mycoplasma infections accounted for 29.1% of the 2,500 infertile couples examined. Mycoplasma is a microorganism that often resides in various parts of the body, including the vagina and cervix of women, and is transferred to the urinary and reproductive systems of men after sexual contact. In general, men with mycoplasma do not suffer from the disease, but they may experience acute symptoms such as frequent urination, urgency and purulent discharge. This condition is a chronic infection with no specific symptoms, but it can lead to infertility. Mumps sequelae A survey found that many men are infertile, often dating back to a history of mumps as a child. The mumps virus, in addition to being a nuisance in the parotid gland, also causes problems in the reproductive organs, nerve tissue and pancreas. When it invades the testicles, it can cause inflammation of the testicles, which is manifested by swelling and pain in the testicles, accompanied by fever, chills, nausea, vomiting and other systemic symptoms. If only these symptoms are present, the problem is not serious. In serious cases, the mumps virus can cause atrophy of the testicular tissue, especially by destroying the mechanism of the seminiferous tubules, the specialized “factory” for sperm production. If both testes are destroyed by this virus, it can cause lifelong infertility, which is difficult to cure. According to statistics, about 14% of men are infertile due to testicular failure, most of which are due to inflammation of the testicles caused by mumps. The varicose veins of the spermatozoa (referred to as spermatozoa) occur due to the existence of congenital valve insufficiency or poor function of the veins themselves, coupled with certain adverse factors (such as excessive force), resulting in increased pressure in the veins of the spermatozoa and the formation of disc-like expansion, which obstructs the return flow of blood to the veins, resulting in insufficient nutrition and oxygenation of the testes, endocrine dysfunction, and a decrease in testosterone levels, thereby inhibiting sperm production. In addition, scrotal inflammation, chronic prostatitis, various types of sperm dysplasia, etc. can trigger male infertility. The most important thing is that if you leave it alone, it will damage your health and cause lifelong pain. Therefore, male infertility must be treated early.
