The prostate is a small walnut-size gland in men that is part of the reproductive system. It helps produce seminal fluid, the fluid that carries semen out of the body during ejaculation. The nerves that control erection and ejaculation are also found in the prostate.
The prostate is located in front of the rectum, which is why it can be felt during your annual physical exam at your doctor's office. It is also positioned under the bladder, where it surrounds the upper part of the urethra. The urethra is the long tube through which urine and semen flow out of the penis. If the prostate becomes enlarged or inflamed, it can put pressure on the urethra and interfere with the normal urine flow. |
