What are the functions of the male sex organs and how do they contribute to the reproductive system?

The male sex organs, including the testes, penis, and prostate gland, have important functions in the reproductive system. The testes produce sperm and the hormone testosterone, which are necessary for reproduction. The penis is used for delivering sperm into the female reproductive system during sexual intercourse. The prostate gland produces fluid that nourishes and protects the sperm. Together, these organs work to produce and deliver sperm for fertilization, contributing to the reproductive process.
