A vasectomy is a permanent contraception method for men. It involves cutting and sealing the tubes that carry sperm from the testicles. This prevents sperm from reaching the semen and fertilizing an egg.
After a vasectomy, you'll still produce semen, but it will no longer contain sperm. You can still ejaculate and have an orgasm, but you won't be able to father a child.
Most men can return to their usual activities within a few days, but you may experience some mild discomfort and swelling. It's important to avoid strenuous activity and sexual intercourse for at least a week so your body can heal.
After a vasectomy, you'll need to use another contraception method for the first 3 months until your sperm count is zero. Your doctor will test your sperm count periodically to make sure it's zero before giving you the all-clear.
In very rare cases, the vasectomy procedure may not be effective and you may still be able to father a child. If this happens, you may need to have a second vasectomy.
