Where do sperm come from and how are they produced in the male reproductive system?

Sperm are produced in the testes, which are located in the male reproductive system. The process of sperm production is called spermatogenesis and it occurs in the seminiferous tubules of the testes. During spermatogenesis, specialized cells called spermatogonia undergo multiple divisions and transformations to eventually form mature sperm cells. These sperm cells are then stored in the epididymis until they are ejaculated during sexual intercourse.
