In the males, the sinus tubercle gives rise to the seminal colliculus.

The margins of seminal colliculus are the following:

Amussat's fold: abnormal folds of the membranous urethra at the level of the seminal colliculus.

The seminal colliculus (Latin colliculus seminalis), or verumontanum, of the prostatic urethra is a landmark near the entrance of the seminal vesicles.

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.
