What are the risks of a vasectomy?

Vasectomy is a safe and simple operation, but there is a small chance you could have problems afterwards. Some of the problems include:

• You may have temporary swelling around the area of the skin that was cut.
• You may have bruising that usually goes away on its own.
• You may get an infection on the skin or inside the scrotum.
• The operation may not make you sterile. A small number of men who have the operation will still be able to get a woman pregnant. The vasectomy is more than 99% effective.
