Almost all vasectomies can be reversed. However, this doesn't guarantee success in conceiving a child. Vasectomy reversal can be attempted even if several years have passed since the original vasectomy — but the longer it's been, the less likely it is that the reversal will work.

Vasectomy reversal rarely leads to serious complications. Risks include:

  • Bleeding within the scrotum. This can lead to a collection of blood (hematoma) that causes painful swelling. You can reduce the risk of hematoma by following your doctor's instructions to rest after surgery. Ask your doctor if you need to avoid aspirin or other types of blood-thinning medication before and after surgery.
  • Infection at the surgery site. This isn't common, but it is a risk with any surgery.
  • Sperm granuloma. Sperm leaking into the scrotum can prompt your immune system to form an inflamed mass called a sperm granuloma. Granulomas may occur after surgery and can be a sign that a vasectomy reversal wasn't successful.
  • Chronic pain. A minority of men have pain in the testicle area (scrotal pain) after vasectomy reversal.
