What does my prostate do?

ANSWER

The prostate is beneath the bladder and in front of the rectum. It’s a walnut-shaped gland that surrounds part of the urethra. (That’s the tube that carries pee and semen out of the penis). Here’s what it does:

If it gets too big, your prostate can block semen or pee from passing through the urethra and out the penis.

  • It produces fluid for semen, which includes sperm produced in the testicles.
  • It prevents urine from being included during ejaculation.
