After a vasectomy, sexual intercourse can resume after 1 week. The procedure can be completed as an outpatient. The patient may experience a small amount of local pain afterward, which can be managed by taking a mild analgesic and applying ice to the site. An additional birth control method should be used until two negative sperm reports at about 6 and 10 weeks have been obtained. Spermatozoa, which were present in the vas deferens at the time of surgery, can remain viable for as long as 6 months.
