MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -LH is transported in the blood stream to the testes, where it stimulates Leydig cells to produce testosterone: this can act as an androgen (via interaction with androgen receptors) but can also be aromatized to produce estrogens.

Detailed explanation-3: -The brain’s hypothalamus and pituitary gland control testosterone production, which is produced in the gonads where the Leydig cells make and secrete testosterone.

Detailed explanation-4: -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-5: -The two testicles (or testes) produce sperm and the male sex hormone testosterone.
