A vasectomy is a minor procedure in which the sperm is blocked from entering the semen. This procedure is usually done under mild sedation in the clinic. Prior to the procedure you will be given medicine to relax, after which a small amount of numbing medicine is injected over the site of the vas deferens (tubes that carry sperm). The vas deferens are then isolated, incised and ligated (tied off). In our clinic we use the “no scalpel technique” allowing for faster healing and less discomfort. After the vasectomy, you will be uncomfortable, however, only ibuprofen, Tylenol, rest and an ice pack are needed.
We recommend rest for the first 2 days, followed only by light activity. Many men return to work the following day, and most feel healed after a week. Sex can be resumed after 1 week, however, only if you are feeling well.
It is important to note that a vasectomy is not effective immediately. New sperm will not be able to travel through the tubes, but there will still be sperm remaining in the vas that takes time to clear. If engaging in sex you will need protection to prevent pregnancy.
Approximately 10–12 weeks after the vasectomy, we will request a semen sample. We look at this under a microscope to ensure no sperm are within the semen.
