In the male reproductive system, sperm cells are produced within the testes, which serve as the primary male gonads.12

Specifically, this production occurs inside the seminiferous tubules, which are numerous, tightly coiled structures located within the lobules of each testis. The process of sperm formation, known as spermatogenesis, takes place within the walls of these tubules, where primitive germ cells called spermatogonia develop into mature spermatozoa. Once formed, the sperm are transported through the tubules and stored in the epididymis to undergo further maturation before they are ready to leave the body.132
