Male reproductive system
Penis
This organ has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped part at the end of the penis. The glans, also called the head of the penis, is covered with a sheath of protective skin called foreskin.
Functions: Penis is the male organ used in sexual intercourse. It conveys urine and seminal fluid to outside the body.
Testes
The testes or testicles are oval-shaped organs that lie in the scrotum and are equivalent to the female ovaries.
-
Scrotum
This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testes, as well as many nerves and blood vessels.
-
Epididymis
The epididymis is a long, coiled tube that rests on the backside of each testicle.
Functions: The job of the epididymis to bring the sperm to maturity (since the sperm that emerge from the testes are immature and incapable of fertilisation). It then transports the sperm cells to the vas deferens.
Vas deferens
The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder.
-
Ejaculatory ducts
These are formed by the fusion of the vas deferens and the seminal vesicles. The ejaculatory ducts empty into the urethra.
-
-
Seminal vesicles
The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The fluid of the seminal vesicles makes up most of the volume of the ejaculatory fluid.
Functions: The seminal vesicles produce a sugar-rich fluid that provides sperm with a source of energy to help them move.
Prostate gland
The prostate gland is a small ball-shaped structure that is located below the urinary bladder in front of the rectum.
Functions: Secretes an alkaline fluid that helps neutralise acidic seminal fluid and enhances motility of sperm.
