ANATOMY

Detailed explanation-1: -Testosterone is indispensable for sperm production, however both testosterone and Follicle Stimulating Hormone (FSH) are needed for optimal testicular development and maximal sperm production.

Detailed explanation-2: -Male reproductive hormones, such as testosterone, help develop and maintain male sex characteristics and help make sperm in the testes.

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: -Testicles (testes) The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
