Where is the male prostate

The prostate is a male-specific reproductive gland organ. It is located under the bladder in the pelvic cavity and surrounds the beginning of the urethra. It is similar in shape and size to a chestnut.

The prostate is an important part of the male reproductive system, and its anatomical location has clear clinical significance. The prostate is close to the bladder neck, adjacent to the rectum posteriorly, connected to the trigone of the bladder above, and connected to the urogenital diaphragm below. This unique location makes it possible for prostate disease to affect urinary function and accessibility for rectal examination. The transverse diameter of the adult male prostate is about 4 cm, the vertical diameter is about 3 cm, the front-to-back diameter is about 2 cm, and the weight is about 20 grams. Physiological hyperplasia may occur with age. The urethra passes through the center of the prostate, and the ejaculatory duct also opens into the prostate urethra. This structure determines the close relationship between the prostate and urination and ejaculation functions.

The surface projection of the prostate is located about 2 cm behind the pubic symphysis, and the posterior surface of the prostate can be palpated clinically through digital rectal examination. A normal prostate has a firm texture, a smooth surface, and a longitudinal groove in the middle. The peripheral zone of the prostate is a common site for prostate cancer, while the transitional zone is prone to benign hyperplasia. The alkaline liquid secreted by the prostate is one of the main components of semen and plays an important role in neutralizing the acidic vaginal environment and maintaining sperm motility. The prostate is located deep and adjacent to important structures, so inflammation or hyperplasia may cause symptoms such as frequent urination, urgency, and difficulty urinating.

It is recommended that men have regular prostate health examinations, especially after the age of 40, they should pay attention to changes in urination. Maintaining moderate exercise, avoiding prolonged sitting, and limiting alcohol intake can help maintain prostate health. If you have persistent urination abnormalities or perineal discomfort, you should seek medical treatment promptly and make a clear diagnosis through prostate-specific antigen testing, ultrasound and other examinations.
