[L. prostata fr. Gr. prostatēs, the one (gland) standing in front]
A gland, consisting of a median lobe and two lateral lobes, that surrounds the neck of the bladder and the urethra in the male. It is partly muscular and partly glandular, with ducts opening into the prostatic portion of the urethra. About 2 × 4 × 3 cm, and weighing about 20 g, it is enclosed in a fibrous capsule containing smooth muscle fibers in its inner layer. Muscle fibers also separate the glandular tissue and encircle the urethra. The gland secretes a thin, opalescent, slightly alkaline fluid that forms part of the seminal fluid.
PATHOLOGY
Inflammation of the prostate may occur, often the result of gonorrheal urethritis. Enlargement of the prostate is common, esp. after middle age. This results in urethral obstruction, impeding urination and sometimes leading to retention. Benign and malignant tumors, calculi, and nodular hyperplasia are common, particularly in men past 60.
