Post Vasectomy Semen Analysis
Patients who have had a vasectomy should be checked for the presence of sperm in the ejaculate as part of their routine follow-up starting two weeks post surgery to verify the success of the procedure. A patientís semen is considered free and clear of sperm when they have two consecutive Post Vasectomy Semen Analysis (PVSA) that show no sperm, motile or non-motile, on the direct exam or centrifuged pellet. A follow up analysis is also encouraged at six months post surgery to rule out the possibility of a spontaneous reconnection. The principle function of the PVSA is to check for the presence or absence of sperm.
