The testes are the male gonadal organs that produce the sex hormones necessary to maintain normal hormone levels in the body. If testicular function is low, male androgen levels will drop significantly, and men will experience a decrease in libido, and it will also cause a decrease in skin hair, such as a decrease in beard, and male sexual characteristics will also become low, such as the throat knot, voice, including male physical strength will also decline. When testicular abnormalities occur, they also cause testicular sperm production disorders. When men check their semen routine, they can find a decrease in the quantity and quality of sperm, which may cause infertility, and this is the primary reason why men often become infertile in clinical practice. When this disease occurs, men should promptly check the causes of low testicular function and timely symptomatic treatment to avoid the progress of this situation.
