It's vital you take some time to rest after your vasectomy
We recommend that you go straight home and rest for 48 hours. Avoid any long periods of standing, walking, or driving for a few days after treatment.
To help your recovery you should take a few days off work to rest. If your job involves physical strain then take a couple of weeks off. Within a week or so you should be comfortable enough to have sex. We just advise you take it easy the first time.
