Where do prostate ducts open?

• A. Into the spongy urethra
• B. Into the penile urethra
• C. Into the bladder
• D. Into the prostatic portion of urethra through 10-12 openings at each side of the seminal colliculus

Answer: (D)

Prostatic ducts drain the secretions of the prostate into the prostatic portion of the urethra. In this segment, their openings are numerous and appear as small orifices on the mucosa around the seminal colliculus (verumontanum). There are about 10–12 openings on each side of the colliculus, making the prostatic urethra the true site where the prostate communicates with the urinary passage. The spongy (penile) urethra is distal to the prostate and does not receive these ducts, and the bladder is not the entry point for the prostatic ducts.
