Post-operative semen analysis
Semen samples are required 12 weeks after the operation to confirm a zero sperm count. Pregnancy after a zero sperm count is very rare. Some patients can take longer to achieve a zero sperm count, and this may  require further semen samples to be done.
All of our vasectomies are audited annually and in 2019 we reviewed the last 5 years which confirmed the success of our procedure is comparatively greater than the national average:
  • Significant bleeding and bruising is 1% 
  • Infection is 0%
  • Post vasectomy chronic pain syndrome is 0%
  • Semen result failure rate after 12 months is 0.2%
  • Pregnancy failure rate is 0%
