Summary
Transurethral resection of the ejaculatory ducts significantly improves semen quality and sperm count in men with infertility. This procedure can lead to successful pregnancies, with results being durable over time.
Area of Science:
- Reproductive Medicine
- Urology
- Semen Analysis
Background:
- Ejaculatory duct obstruction (EDO) is a cause of male infertility.
- Transrectal ultrasound (TRUS) is used to diagnose EDO.
- Semen quality parameters are crucial indicators in male infertility assessment.
Purpose of the Study:
- To evaluate the impact of transurethral resection of the ejaculatory ducts (TURED) on semen quality.
- To assess TURED outcomes in patients with azoospermia and oligo-asthenospermia.
Main Methods:
- Retrospective review of 46 patients undergoing TURED for EDO.
- Diagnosis confirmed by transrectal ultrasound.
- Semen parameters assessed pre- and post-operatively.
Main Results:
- 65% of patients showed improved semen quality ( >50% increase in total motile sperm count).
- 20% achieved pregnancy within 6.1 months post-surgery.
- Statistically significant and sustainable increases in sperm count observed in azoospermic and oligo-asthenospermic groups.
Conclusions:
- TURED offers significant and durable semen quality improvement for various surgical indications.
- The reasons for treatment failure in some cases remain unclear.
