What is benign prostatic hyperplasia (BPH)?

Benign prostatic hyperplasia (BPH) is a condition in which the prostate, a walnut-sized body part made of glandular and muscular tissue, grows in size. The prostate surrounds part of the urethra, which is the tube that carries urine and sperm out of the body. The benign (noncancerous) condition is also called benign prostatic enlargement (BPE).

The prostate is located directly beneath the bladder and in front of the rectum. The urethra passes through the prostate, so if the prostate becomes enlarged, it can keep urine or semen from passing through the urethra.

The main function of the prostate is to produce fluid for the semen, the milky fluid in which sperm swims. Sperm is produced in the testicles, which also make the main male hormone testosterone. During puberty, testosterone stimulates the growth and function of the prostate, and helps with the production of fluid for semen.
