The prostatic utricle (Latin for "pouch of the prostate") is a small indentation located in the prostatic urethra, at the apex of the urethral crest, on the seminal colliculus (verumontanum), laterally flanked by openings of the ejaculatory ducts. It is also known as the vagina masculina or (in older literature) vesicula prostatica.[1]

Structure
It is often described as "blind", meaning that it is a duct that does not lead to any other structures.[citation needed]
It can sometimes be enlarged.[2][3]
Dissection of prostate showing prostatic utricle opening into the prostatic urethra.
Function
The prostatic utricle might serve no function.[citation needed] It is important primarily because it is the male homologue of the female uterus and vagina, usually described as derived from the Müllerian ducts,[4] although this is occasionally disputed.[5]
In 1905 Robert William Taylor stated the function of the utricle thusly: "In coitus it so contracts that it draws upon the openings of the ejaculatory ducts, and thus renders them so patulous that the semen readily passes through."[6]
