Where is sperm produced in the male body?

Sperm production occurs in the testes, which are the male reproductive organs responsible for generating sperm cells through a process called spermatogenesis. The testes contain seminiferous tubules where the sperm are developed from germ cells. Once mature, sperm cells move to the epididymis, where they gain motility and are stored until ejaculation.

The other locations mentioned, like the epididymis, prostate gland, and seminal vesicles, play different roles in the male reproductive system. The epididymis is crucial for the maturation and storage of sperm but does not produce sperm itself. The prostate gland and seminal vesicles contribute to the production of seminal fluid, which helps in carrying the sperm during ejaculation but are not involved in the actual creation of sperm cells. Thus, the correct answer emphasizes the specific role of the testes in sperm production.
