In recent years, the number of infertile patients has increased, and some of them are caused by some diseases. What diseases may cause infertility? Below is an introduction to some diseases that can easily lead to infertility for your reference.
Varicocele
The occurrence of varicocele (referred to as varicocele) is due to the presence of congenital valve dysfunction or dysfunction in the vein itself, coupled with certain acquired adverse factors (such as excessive exertion), resulting in increased pressure in the internal spermatic vein, forming a discoid expansion, which impedes the blood flow of the vein, leading to insufficient testicular nutrition and oxygen supply, endocrine dysfunction, and decreased testosterone levels, thereby inhibiting sperm production. In addition, scrotal inflammation, chronic prostatitis, and various sperm disorders can cause male infertility.
Cryptorchidism
In medicine, abnormal testicular position or failure to descend to the scrotum is referred to as cryptorchidism. According to statistics, about 10% of newborns and 2% of young children will find abnormal testicular position. Previously, it was believed that only bilateral cryptorchidism would affect fertility, but in recent years, it has been found that the infertility rate of unilateral cryptorchidism accounts for over 67%. Although theoretically speaking, the unilateral cryptorchidism can completely compensate for the effects of two testicles, in fact, due to the adverse effects of temperature, the unilateral cryptorchidism correspondingly produces certain antibodies against sperm, thereby depriving the opposite normal testicle of its ability to produce sperm. This type of infertility, known as "blood testicular disorder," also has a greater chance of developing testicular tumors than normal men. Moreover, due to misconceptions in traditional concepts, it has not yet attracted attention. It is usually discovered after marriage, when the treatment effect is often not as effective as in childhood.
Sequela of parotitis
A survey has found that many men are infertile, often dating back to their childhood history of mumps. In addition to "committing crimes" in the parotid gland, the mumps virus can also "cause trouble" in the reproductive organs, nervous tissues, and pancreas of the human body. "When it invades the testicles, it can cause testicular inflammation, characterized by testicular swelling and pain, accompanied by systemic symptoms such as fever, chills, nausea, and vomiting.". "If only the above symptoms occur, the problem is not very serious. The serious problem is that the mumps virus can atrophy testicular tissue, especially causing damage to the" factory "specialized in the production of sperm - the institutions of the sperm convoluted tubules.". "If both testicles are damaged by this virus, it can lead to lifelong infertility, which is difficult to cure.". According to statistics, about 14% of men are infertile due to testicular failure, most of which are caused by orchitis caused by mumps.
mycoplasma infection
According to research, a considerable number of male infertility is related to various viral and bacterial infections. For example, mumps virus, gonococcus, Escherichia coli, Staphylococcus aureus, Staphylococcus albicans, and mycoplasma infections between viruses and pathogens. Among them, foreign scholars found that 29.1% of 2500 infertile couples were infected with Mycoplasma. Mycoplasma is a microorganism that often inhabits various parts of the human body, mostly in the vagina and cervix of women, and transfers to the urinary and reproductive systems of men after sexual contact. Generally, men carrying mycoplasma do not cause symptoms, but they may experience acute symptoms such as frequent urination, urgency of urination, and purulent secretions. Although this condition is a chronic infection without specific symptoms, it can lead to infertility.
Chlamydia trachomatis
Perhaps the research conclusion that trachoma can cause male infertility will surprise you. In fact, chlamydia trachomatis infection can cause male urethritis, vasculitis, epididymitis, and sexual dysfunction. Due to inflammation of the vas deferens, sperm motility is reduced, leading to infertility.
