The prostate gland is a small, walnut-sized gland located in the male reproductive system. It is responsible for producing the majority of the fluid that makes up semen. The prostate is located just below the bladder and in front of the rectum, and it wraps around the urethra, the tube through which urine passes out of the body. The prostate plays an important role in the reproductive system, as it helps to propel semen during ejaculation.
