No scalpel vasectomy. With a no-scalpel vasectomy, your doctor will need to numb the skin of your scrotum. Some doctors use traditional local anesthetic administered with a needle. Other doctors offer no-needle numbing, which uses a spray to apply topical numbing medicine. Anti-anxiety medication is also available if you want it.
Instead of making an incision into the scrotum, your doctor will make a small puncture into the skin then stretch the skin gently to see inside. They will then use the same technique as a traditional vasectomy to cut and seal the vas deferens. The puncture closes immediately after the procedure without any need for stitches.
Recovering from a No-Scalpel VasectomyThe real benefits of a no-scalpel vasectomy come in the recovery period. The recovery time for a traditional vasectomy is close to a week, with lingering soreness, swelling, and bruising. After a no-scalpel vasectomy, most people can resume normal activity levels after only a few days. There is less bruising and swelling.
No matter which type of vasectomy you have, it will not be fully effective until several months after your procedure. When you have your vasectomy, the sperm that were in the position to be ejaculated can live for many weeks. You could ejaculate them and cause a pregnancy during that time.
Your doctor will ask you to have a follow-up appointment 90 days after your vasectomy to check for any remaining sperm. Use a reliable method of contraception until you know that you're no longer ejaculating live sperm.
Vasectomies are very reliable as a form of birth control. Fewer than 1% of vasectomies fail.
