Prostate WHAT IS THE PROSTATE The prostate gland is a solid, chestnut-shaped organ surrounding the first part of the urethra in the male body. The prostate gland is situated immediately under the bladder and in the front of the rectum. The prostate gland produces secretions that form part of the seminal fluid during ejaculation. The ejaculatory ducts from the seminal vesicles pass through the fluid during ejaculation. The ejaculatory ducts from the seminal vesicles pass through the prostate gland to enter the urethra. The prostate gland weighs only a few grams at birth. Enlargement starts at puberty from the effect of androgen hormones and stops at around the age of 20, when it reaches its adult weight of about 20 grams. In most men, the prostate begins to enlarge further after the age of 50. The prostate gland consists of two main zones; an inner zone (which produces secretions responsible for keeping the lining of the urethra moist) and an outer zone (which produces seminal secretion). Prostatic problems very rarely occur before the age of 30.
