Rare problems that might occur after your vasectomy include bleeding, infection and a mild inflammatory reaction to sperm that may have gotten loose during the surgery (called sperm granuloma).
Another risk is that the ends of the vas deferens may find a way to create a new path to one another. This is a very rare occurrence. But if it happens, you could be able to cause a pregnancy.
Call your doctor if:
- You have a fever.
- You have swelling that won't go down or keeps getting worse.
- You have trouble urinating.
- You can feel a lump forming in your scrotum.
- You have bleeding from an incision that doesn't stop even after you've pinched the site between 2 gauze pads for 10 minutes
