The Prostate

The prostate is part of a man's reproductive system. It's located in front of the rectum and under the bladder. The prostate surrounds the urethra, the tube through which urine flows.

A healthy prostate is about the size of a walnut. If the prostate grows too large, it squeezes the urethra. This may slow or stop the normal flow of urine.

The prostate is a gland. It makes part of the seminal fluid. During orgasm, the seminal fluid helps carry sperm out of the man's body as part of semen.
