OBJECTIVE: To evaluate the feasibility and efficacy of transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation in treating patients with Müllerian duct cyst. 
 METHODS: We retrospectively analyzed 12 infertile men due to Müllerian duct cyst between 2009 and 2012. They were diagnosed by semen analysis (including quantity of semen, pH and fructose), digital rectal examination, transrectal ultrasonography, magnetic resonance images and aspiration biopsy when necessary. All patients were treated by transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation and were followed up for 12 months. 
 RESULTS: A significant improvement of semen quality was achieved after surgery and the sperms could be seen. The patients' semen was analyzed for 3 times in 12 months and the results were normal. Semen volume and pure berries of the patients were increased after the operation compared with those before the operation (P<0.05). Spontaneous pregnancies were achieved in 3 patients 9-12 months after surgery. Four patients' seminal vesicle became smaller obviously.
 CONCLUSION Transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation is effective and safe for the treatment of Müllerian duct cyst accompanied with ejaculatory duct obstruction.
