According to AUA guidelines, patients should refrain from ejaculation for approximately 1 week after vasectomy. Among the guidance that AUA suggests clinicians provide to patients is informing men that although vasectomy is intended to be a permanent form of contraception, it does not produce immediate sterility. Following vasectomy, another form of contraception is required until vas occlusion is confirmed by post-vasectomy semen analysis (PVSA). Patients may stop using other methods of contraception when examination of one well-mixed, uncentrifuged, fresh post-vasectomy semen specimen shows azoospermia or only rare nonmotile sperm (RNMS or ≤ 100,000 nonmotile sperm/mL). The PVSA should be performed 8-16 weeks after vasectomy. When to do the first PVSA should be left to the judgment of the surgeon.
AUA does not recommend the routine use of prophylactic antimicrobials for vasectomy unless the patient is at high risk for infection. The guidelines also specify that clinicians do not need to routinely discuss prostate cancer, coronary heart disease, stroke, hypertension, dementia, or testicular cancer during pre-vasectomy counseling of patients because vasectomy is not considered a risk factor for these conditions.
