What does the prostate do?

ANSWER

It's a small gland that's part of the male reproductive system. It's supposed to be about the shape and size of a walnut.

It rests below your bladder and in front of your rectum. It surrounds part of the urethra, the tube in your penis that carries pee from your bladder.

The prostate helps make some of the fluid in semen, which carries sperm from your testicles when you ejaculate.
