Which risks are there?
Vasectomy is a surgical procedure which involves closing off the tubes (called the vas deferens) that carry sperm out of your testicles. It is a permanent form of contraception because once these tubes have been closed, there will no longer be any sperm in your semen and you can’t get your sexual partner pregnant.
Any operation carries the risk of some side effects. The most common side effects of vasectomy are bruising, swelling and mild discomfort in the scrotum. These side effects should usually only last a few days. If you feel pain or discomfort in the scrotum you can take mild painkillers such as paracetamol. If the pain continues for more than a few days and is not relieved by paracetamol, talk to your doctor.
Don’t be alarmed if you see some blood in your semen the first few times you ejaculate after vasectomy. This is common and should resolve itself.
There is also a slight risk of infection after the surgery, which can be caused by bacteria getting into the cuts made by the surgeon in your scrotum. It is very important to keep the area dry and clean to reduce the risk of getting an infection after vasectomy.
