Section 1. Highly Effective Non-hormonal Methods Available in the US


A permanent form of birth control, vasectomy has been used for decades for male sterilization. The outpatient procedure is highly effective and has few side effects. Vasectomy is exceedingly safe.


Two techniques are used to perform vasectomies: no-scalpel vasectomy (NSV) and no-needle/no-scalpel vasectomy (NNV). NSV is considered the standard of care. In NSV, the physician uses a small needle to inject anesthesia into the skin and vas deferens. male sterilization vasectomyIn NNV, the physician uses a piston-like instrument to force anesthetic into the tissues. After anesthetizing the area, the provider creates a small opening (a few millimeters) in the skin of the scrotal sac and locates the vas deferens. The vas are then ligated or cauterized; there is no need for sutures.

Sexual activity may be resumed about 1 week after the procedure or the time at which the patient feels comfortable. A backup contraceptive method is needed until the patient has had at least one negative sperm check at least 3 months after the procedure AND at least 20 ejaculations.13 These checks are essential to ensure the absence of residual sperm in the vas beyond the point of occlusion.
