The effect of perioperative distal vasal lavage on subsequent semen analysis after vasectomy: a prospective randomized controlled trial.

Abstract

To determine the effect of perioperative distal vasal lavage with 50 mL of normal saline on subsequent time to azoospermia after vasectomy. Seventy-two patients were prospectively enrolled and randomized to undergo vasectomy with or without vasal lavage. Infertility rates at 8, 10 and 12 weeks were compared for both groups and for those undergoing the procedure under local or general anaesthesia. Patient compliance for returning postoperative semen for analysis was also assessed. There was no statistically significant difference in infertility rates at 8, 10 or 12 weeks after vasectomy with or without vasal lavage. Vasectomies performed under local and general anaesthesia had comparable rates of infertility at 12 weeks after surgery. Compliance in providing semen for analysis was poor. The routine adoption of distal vasal lavage during vasectomy for contraception cannot be recommended. As compliance in providing semen for analysis was poor, the clinician has a responsibility to remind the patient of the consequences of such action.
