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, laterally flanked by openings of the ejaculatory ducts.

It is often described as "blind", meaning that it is a duct which does not lead to any other structures.

[edit] Embryology

It serves no function. Its importance is primarily because it is the male homologue of the female uterus and vagina, derived from the Müllerian ducts. (See List of homologues of the human reproductive system for more details.)
