Illustration of the prostate with a non-specific pathological change in the inside of the prostate. Tubuloalveolar glands, elastic elements, smooth muscle and connective tissue form the "prostate gland". It lies around the male urethra, connected at the base to urethra and seminal vesicles, ventrally connected to ligamentum puboprostatica, seperated from the rectum by septum rectovesicale and serosal rudiments. It is, i a normal adult male, about as big as a chestnut.
