The rate of complications is low (less than 4%)

Within the first few days, the main complications are:

1. Bruising or Haematoma formation is rare but can be significant. It can be painful and may take weeks to disappear. Some degree of minor swelling is common but painless.
2. Wound Infection can occur as with any operation.It is uncommon and easily treated.

1. Post Vasectomy Pain syndrome is a very rare and poorly understood condition when a man experiences ongoing discomfort some months after a Vasectomy.
   Thankfully most cases resolve after simple measures such as conventional analgesics.
2. Sperm Granuloma/Cyst at the end of the tube where the Sperm exits.
   These are rare, usually small, and painless. Treatment is rarely necessary.
3. Vasectomy Failure can be Primary(due to an operative failure so sterilisation is never achieved),or Secondary (When Sterilisation is proven on testing but at a later date live sperm  reappear because the tubes spontaneously rejoin or an alternative pathway develops). This happens in less than 1 in 1,000 cases.

1. Do vasectomies interfere with sexual function?
   Vasectomy does NOT interfere with sexual function and is not associated with an increased risk of Cancer of the Testis, Prostate, or other health risks.
2. Is a follow up appointment necessary?
   A follow-up Semen test is needed 3 months after the operation to confirm that there are no Sperm coming through.
   This is required because there are already at least 20 ejaculations are stored in the seminal vesicles so the man is still fertile until these are cleared.
   Until that test is clear alternative contraception must be used.
