GENERAL HISTOLOGY

Detailed explanation-1: -Most men have two 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.

Detailed explanation-2: -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-3: -As in women, gonadotropin releasing hormone, or GnRH, is released in a pulsatile fashion, stimulating the release of follicle stimulating hormone (FSH) and leutinizing hormone (LH). In men, LH primarily stimulates testosterone production, while FSH stimulates the production of sperm.

Detailed explanation-4: -Testicle. The testes, the primary reproductive organs in males, generate sperm cells and produce the hormone testosterone. The testes are the primary reproductive organs and generate sperm cells through a process called spermatogenesis.
