Summary
The ejaculatory duct openings in men are located beside the verumontanum, near the prostatic utricle opening. This finding provides anatomical evidence for treating ejaculatory duct obstruction and performing seminal vesiculoscopy.
Area of Science:
- Urology
- Male Reproductive Anatomy
Background:
- Ejaculatory duct obstruction is a cause of male infertility and other reproductive issues.
- Accurate anatomical knowledge is crucial for effective diagnosis and treatment.
Purpose of the Study:
- To precisely locate the ejaculatory duct openings in males.
- To provide anatomical evidence supporting seminal vesiculoscopy and treatment of ejaculatory duct obstruction.
Main Methods:
- Ureterocystoscopy was performed on 21 male patients (aged 26-47) presenting with various urological conditions.
- Prostate and ejaculatory duct massage was conducted, and expelled fluid was observed and analyzed microscopically for sperm.
Main Results:
- Ejaculatory duct openings were identified on the sides and lower sides of the prostatic utricle, above the verumontanum, and on the ventral side of the verumontanum.
- Sperm were detected in the expelled fluid of 13 patients; no expulsion was observed from the prostatic utricle opening in others.
Conclusions:
- Male ejaculatory duct openings are anatomically situated adjacent to the prostatic utricle opening, on either side of the verumontanum.
- This precise anatomical location is vital for understanding and managing ejaculatory duct obstructions.
