ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Your hypothalamus and pituitary gland control the amount of testosterone your gonads (testicles or ovaries) produce and release. Your hypothalamus releases gonadotropin-releasing hormone (GnRH), which triggers your pituitary gland to release luteinizing hormone (LH).

Detailed explanation-3: -In men, LH primarily stimulates testosterone production, while FSH stimulates the production of sperm.

Detailed explanation-4: -1.1. Testosterone is the major androgen in the testis that regulates spermatogenesis. Testosterone is produced by the Leydig cell in response to stimulation with luteinizing hormone (LH) and acts as a paracrine factor that diffuses into the seminiferous tubules.

Detailed explanation-5: -The main hormone secreted by the testes is testosterone, an androgenic hormone. Testosterone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells.
