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.

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

Detailed explanation-4: -The testes synthesize two important products: testosterone, needed for the development and maintenance of many physiological functions; and sperm, needed for male fertility.
