Prostatic ducts open into the prostatic urethra at how many openings on each side of the seminal colliculus?

• A. 2-3 openings
• B. 4-6 openings
• C. 8-9 openings
• D. 10-12 openings

Answer: (D)

Prostatic ducts are numerous channels from the prostate that drain into the prostatic urethra. Their openings are located on the posterior wall of the prostatic urethra around the seminal colliculus (verumontanum). The seminal colliculus serves as the central landmark for where the ejaculatory ducts open, while the prostatic ducts open in multiple small orifices on both sides of it. Overall there are about 20 to 30 prostatic ducts, so they are distributed as roughly 10 to 12 openings on each side of the seminal colliculus. That distribution explains why the answer is 10-12 openings on each side.
