Detailed explanation-1: -Testosterone is required for sperm production, but the level in the testes where sperm are produced is many times higher than in the blood. Even men with low or borderline T levels may have sufficient T levels for sperm production.

Detailed explanation-2: -Testosterone is a sex hormone that plays important roles in the body. In men, it’s thought to regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm.

Detailed explanation-3: -In men, LH primarily stimulates testosterone production, while FSH stimulates the production of sperm. The testes must be capable of response to this hormonal stimulus.

Detailed explanation-4: -Testosterone is also essential for the release of mature spermatozoa from Sertoli cells. It has been shown that in the absence of testosterone stimulation, sperm are not released but are instead phagocytized by Sertoli cells [7].
