Prostatic Utricle

The prostatic utricle is a section of the first portion of three which form the male urethra. The prostatic utricle forms a cul-de-sac about 6 mm. long, which runs up and back in the substance of the prostate behind the middle lobe. Some authors call it the "uterus masculinus," because it corresponds to the uterus and vagina in the female.
