Will having a vasectomy hurt?

A vasectomy is safe and effective, but does involve a small operation. You may feel some discomfort during the procedure, but most men tolerate it well and do not find it painful.

Non-scalpel Vasectomy and Anaesthetic

Before the procedure starts, a fast-acting local anaesthetic (lidocaine 2%) is given with a small needle into the skin directly above the vase deferens (sperm-carrying tube). We do not inject your testes or operate on them, rather the vas deferens as it emerges above the testes. The anaesthetic is given directly into the area which numbs it immediately. Some men feel a tugging sensation or a pain in their lower abdomen, but most describe the procedure as uncomfortable rather than painful.

Non-scalpel Vasectomy and painkillers

You may feel pain in the area after the anaesthetic has worn off and as the wound heals. This should be manageable with painkillers such as ibuprofen or paracetamol. We do encourage clients to refrain from strenuous activity for a few weeks to support fast healing. For more detailed information, read our vasectomy aftercare advice.

A small number of men have been known to experience long term testicular pain following a vasectomy, which may require follow-up treatment, but this is very rare.
