Male Reproductive System-

• The male reproductive system is composed of a pair of testes, the male sex accessory ducts and the accessory glands and external genitalia.
• Each testis has about 250 compartments called testicular lobules, and each lobule contains one to three highly coiled seminiferous tubules.
• Each seminiferous tubule is lined inside by spermatogonia and Sertoli cells.
• The spermatogonia undergo meiotic divisions leading to sperm formation, while Sertoli cells provide nutrition to the dividing germ cells.
