The prostate is a walnut-sized gland that is present only in men. It is located deep in the pelvis just below the bladder, it surrounds the tube known as the urethra (i.e the urethra passes through the prostate). The urethra is the tube that carries urine from the bladder out through the penis.
Prostate can be examined through the rectum, as it sits in front of the rectum.
Fluid produced by the prostate forms part of the semen at ejaculation. The fluid produced by the prostate nourishes sperm and helps with fertilisation of female egg. The prostatic fluid contains large amounts of a substance known as prostate-specific antigen (PSA), which liquefies the gelatinous sperm mixture after ejaculation.
There are three major conditions that affect the prostate: Prostate cancer, enlargement of prostate (benign condition, otherwise known as benign prostatic hyperplasia, BPH) and prostatitis.
