A : Male reproductive organs are outside the body. They include the penis, and a pair of testes inside a cover called a scrotum. The testes produce sperm and the male hormone testosterone. During sexual intercourse, sperm travels down the penis. The female reproductive system is also in the pelvic region, but it is inside the body.
