Seminal colliculus

The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark distal to the entrance of the ejaculatory ducts (on both sides, corresponding vas deferens and seminal vesicle feed into corresponding ejaculatory duct). Verumontanum is translated from Latin to mean 'mountain ridge', a reference to the distinctive median elevation of urothelium that characterizes the landmark on magnified views.

Embryologically, it is derived from the uterovaginal primordium. The landmark is important in classification of several urethral developmental disorders. The margins of seminal colliculus are the following:

• the orifices of the prostatic utricle
• the slit-like openings of the ejaculatory ducts.
• the openings of the prostatic ducts
