Read and learn more. The Male Reproductive System. The penis and the scrotum are the male’s external organs. The penis is his organ of reproduction and is also used for urination. Behind the penis is a sac-like skin that supports the testes. The testes produce billions of sperm cells. These sperm cells travel from the testes through the vas deferens, tubes c ircling the bladder. As the sperm cells travel through the vas deferens some glands (seminal vesicle, p rostate and Cowper) provide it with lubricating fluids that enable it to move. The sperm cells plus the lubricating fluids is now called semen. The semen leaves the male body through the urethra.
