The Male Reproductive System. Testes are suspended outside the abdominal cavity by the scrotum, a pouch of skin that keeps the testes close or far from the body at an optimal temperature for sperm development.Seminiferous tubules are inside each testis, and are where sperm are produced by meiosis.About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn develop into mature sperm. The male reproductive system.he Male Reproductive System.
