Click here to see our table of success and pregnancy rates in a long term review of nearly 1000 consecutive cases treated here at Dawson Microsurgery
These statistics are based on a review of 315 consecutive cases. In each case the surgeon was Dr Dawson and they attended the clinic between September 2002 and February 2004.
The figures include first time reversals and re-do reversals (of which 5% had undergone previous surgery in another clinic). In common with every other reversal service we have difficulty in contacting our former patients, usually because they have moved away or changed phone numbers etc. Whilst many couples are keen to share happy news of pregnancy and results, many do not let us know their outcomes. So this survey is the result of detailed follow up.
Headline rates are; overall patency 95.5% patency and 55% pregnancy.
Success rates are dependent on the time since the original vasectomy with the risk of suffering ‘blow-out’ (so not able to benefit from reversal) increasing by 2 % per year after the vasectomy. In this survey the commonest post vasectomy interval was 5 years with a range of 1-30 years.
