GENERAL HISTOLOGY

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

Detailed explanation-3: -Testosterone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells. The testes also produce inhibin B and anti-Müllerian hormone from Sertoli cells, and insulin-like peptide 3 (INSL3) and oestradiol from the Leydig cells.

Detailed explanation-4: -When the testes are exposed to FSH from the pituitary, Sertoli cells within seminiferous tubules in the testes produce sperm through meiosis.

Detailed explanation-5: -The testes synthesize two essential products: testosterone, needed for the development and maintenance of many physiological functions including normal testis function; and sperm, needed for male fertility.
