Risks

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 has 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, use scrotal support and apply ice packs 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. Although very uncommon, infections are a risk with any surgery and may require treatment with antibiotics.
• Chronic pain. Persistent pain after vasectomy reversal is uncommon.
