Now Playing: The Male Reproductive System
Video Text
The main elements of the male reproductive system include the penis, the scrotum, the testes, the epididymis, the urethra, and the prostate gland.
The penis is the primary male organ for sexual intercourse. The penis is composed of two main parts: The shaft, or body, and the glans, or head. At the end of the glans is a small opening, where semen and urine exit the body.
The scrotum is the sack of skin that hangs at the base of the shaft, below the penis. The scrotum acts as shock absorber, protecting the testicles from harm. It also helps to regulate the temperature of the testes, which is important for the production and health of sperm.
The testes are two, oval-shaped organs, that are contained within the scrotum. The primary functions of the testes are producing testosterone, and making sperm.
The epididymis is a coiled tube on the back of each testicle. The epididymis functions to transport and store the sperm produced in the testes.
The urethra is a tube that carries urine from the bladder, and sperm from the testes, through the penis, and outside of the body.
The prostate gland surrounds the urethra, and is located inside of the body, below the bladder, and in front of the rectum. The prostate gland provides additional fluid to the ejaculate, which helps to nourish the sperm.
