The prostatic utricle (Latin for "pouch of theprostate ") is a small indentation located in theprostatic urethra , at the apex of theurethral crest , on theseminal colliculus , laterally flanked by openings of theejaculatory duct s. It is also known as the vagina masculina.It is often described as "blind," meaning that it is a duct that does not lead to any other structures.
It can sometimes be enlarged.cite journal |author=Meisheri IV, Motiwale SS, Sawant VV |title=Surgical management of enlarged prostatic utricle |journal=Pediatr. Surg.

Embryology
It may serve no function. However, in "A Practical treatise on sexual disorders of the male and female" 3rd ed. By Robert William Taylor, it states "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." [R. W. Taylor. A practical treatise on sexual disorders of the male and female. New York and Philadelphia, 1897; 3rd edition, 1905. P. 48]
It is important primarily because it is the male homologue of the female
uterus andvagina , usually described as derived from theMüllerian ducts , though this is occasionally disputed.cite journal |author=Shapiro E, Huang H, McFadden DE, "et al" |title=The prostatic utricle is not a Müllerian duct remnant: immunohistochemical evidence for a distinct urogenital sinus origin |journal=J. Urol. |volume=172 |issue=4 Pt 2 |pages=1753–6; discussion 1756 |year=2004 |pmid=15371806 |doi=] (SeeList of homologues of the human reproductive system for more details.) Theparamesonephric (Mullerian) duct obliterates in the male, forming the prostatic utricle and in the female becomes thefallopian tube anduterus .References
