Ejaculation and sexual function after endoscopic bladder neck incision

Endoscopic incision of the bladder neck, performed to relieve outflow obstruction, was evaluated as regards effects on ejaculation and orgasm in 61 men (mean age 48 years) by analyses of seminal fluid and a questionnaire. Relief of obstruction was confirmed by post-operative normalisation of urinary flow. In 47 cases there was unchanged antegrade ejaculation, while reduced semen volume was reported by 11 men and retrograde ejaculation by only 3. The quality of orgasm and sexual satisfaction were not permanently changed by the operation. Post-operative analysis of seminal fluid was performed in 27 patients, with normal results in 26. In 16 men who provided specimens both before and after bladder neck incision, no consistent change was found in the semen. An incision completely splitting the bladder neck but not extending distal to the verumontanum will relieve outlet obstruction. Maintenance of antegrade ejaculation can be expected in most patients undergoing this operation.
