In order for males to generate sperm they need the hormone testosterone, which is manufactured in the testes. Sperm is produced inside the seminiferous tubules, which are coiled masses of tubes. The female reproductive system is responsible for the release of eggs which are necessary for reproduction.
The testes are the male gonads. Like the ovaries, the testes are paired organs, but unlike the ovaries, the testes are found outside the pelvic cavity and are contained in the scrotal sac. The testes are the organs that produce sperm, which is the male reproductive cell. Ã
