The prostate gland, which produces some of the parts of semen, surrounds the ejaculatory ducts at the base of the urethra, just below the bladder. The key male reproductive organs include the testes, epididymis, urethra, vas deferens, prostate gland, seminal vesicle, and penis. This is the male organ used in sexual intercourse. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth or farther away from the body to cool the temperature. The sperm use their tails to push themselves into the epididymis, where they complete their development. As the penis fills with blood , it becomes rigid and erect, which allows for penetration during sexual intercourse. The vas deferens is a muscular tube that passes upward alongside the testicles and transports the sperm-containing fluid called semen. The seminal vesicles are located behind the prostate and the bladder.
