Prostate | |||
The prostate consists of glands, fibrous tissue and muscle cells. It lies at the neck of the bladder, in front of the anterior wall of the rectum (through which it can be felt by the finger of an examining physician - an essential part of assessment of prostatic size and potential cancer). The tube that conveys urine from the bladder to the penis - the urethra - passes through it, and receives the openings of a number of prostatic ducts together with the ejaculatory ducts. During ejaculation the prostate secretes a small amount of alkaline fluid which is thought to aid the progression of sperm. In youth and young adulthood it is relatively small: after the age of 40 it enlarges. | |||
