No. Before the vasectomy, the doctor may give you a mild sedative to relax you. After surgery you may be a little sore for a few days. Generally, two or three day's rest is enough time for recovery before men can return to work and most normal, non-strenuous physical activity. Sex can usually be resumed 7 days after the procedure. Afterwards, you will be sore for a couple of days, and you might want to take a mild painkiller. But the discomfort is usually less with the no-scalpel technique, because there is less injury to the tissues. Your doctor or nurse will provide you with complete instructions about what to do after surgery.
