Where the prostate is
The prostate is a gland found only in men. It surrounds the urethra, which is the tube that carries urine from the bladder to the penis. This tube also carries semen.
What the prostate does
The prostate gland makes the fluid part of semen. It needs the male sex hormone, testosterone, to grow and function. Some treatments for prostate cancer work by reducing the levels of testosterone.

Men have a small gland about the size of a walnut called the prostate gland. The prostate surrounds the first part of the tube (urethra) which carries urine from the bladder to the penis. The same tube also carries sex fluid (semen). The prostate gland is divided into 2 lobes, to the left and the right of a central groove.
The prostate gland produces a thick clear fluid which is an important part of the semen. The growth and function of the prostate depends on the male sex hormone testosterone, which is produced in the testes. Some treatments for prostate cancer work by lowering the levels of testosterone.
