The key to male fertility is sperm. If the number of sperm is too small or the quality is not high, it is easy to have problems. What are some diseases that may lead to oligospermia? Below is an introduction to common diseases that induce male oligospermia for your reference.
Diseases that Induce Male Oligospermia
Endocrine abnormalities
The normal spermatogenic function of men depends on the normal function of the hypothalamus pituitary gonad axis. Any link obstacle will affect the spermatogenic function. Other diseases such as thyroid and adrenal gland diseases will also affect the gonad function and cause oligospermia.
Inflammation of the urinary and reproductive systems
Including orchitis, epididymitis, seminal vesiculitis, prostatitis, urethritis, etc., these patients have the highest proportion in oligospermia. Inflammation of the genitourinary tract can directly affect testicular spermatogenic function, and can also cause the production of anti sperm antibodies in the blood or semen, affecting the acidity and alkalinity of semen. In addition, the direct killing effect of pathogens on sperm can lead to reduced sperm count.
Varicocele
Infertility caused by varicocele accounts for 30-40% of male infertility. The testicular spermatogenesis function is affected due to the increase of testicular temperature and toxin accumulation, which can lead to oligospermia, or even azoospermia in serious cases. The initial symptoms of varicocele are not obvious, and in severe cases, the scrotum may feel bloated and bulged, with protrusions resembling earthworm like blood vessels. Semen examination shows a decrease in sperm count, poor motility, and an increase in abnormal sperm count.
Excessive scrotal temperature
The seminiferous tubules in the testes, which are specifically used to produce sperm, are very sensitive to temperature changes. The suitable temperature for this area is 2-3 ℃ lower than the human body temperature. Excessive temperature can easily inhibit the survival and maturation of sperm, resulting in a decrease in the number of sperm in the semen or a decrease in motility. Therefore, male friends should wear less tight pants, take less saunas, avoid electromagnetic radiation and high temperatures, and develop good living habits.
Cryptorchidism
There are research reports that about 30% to 60% of patients with unilateral cryptorchidism are infertile, while 50% to 100% of patients with bilateral cryptorchidism are infertile. In oligospermia, cryptorchidism accounts for about 9%. In addition to the degeneration of the seminiferous tubules that affects spermatogenesis, the completely descended testicles on the other side of the cryptorchidism may also have varying degrees of damage, possibly due to the impact of anti sperm antibodies produced by the cryptorchidism on normal testicles.
