ABSTRACT
The human prostate gland is shaped like an inverted cone. It lies at the base of the bladder and completely encircles the urethra. Also entering the prostate are the ejaculatory ducts. These run through the cranial part of the gland and open into the urethra at the verumontanum (Fig. 1). In the young man, the prostate weighs between 15 and 20 g. It consists of glandular tissue, which is responsible for secreting fluid (contributing to approximately 12% of the normal ejaculatory volume), and nonglandular tissue, which forms the prostatic sphincters and fibromuscular capsule.
