This is not enough, though. Personal experience, however much of it you have, has to be supported by evidence from medical science. Mr Harriss makes choices based on the huge medical literature on vasectomy reversal surgery, and chooses techniques based on the evidence of which ones have the highest vasectomy reversal success rate. This means ignoring a number of supposed “gold standard” surgical techniques which are not supported by evidence.
For example, multiple studies have shown there is no evidence that multi-layer techniques for rejoining the vas deferens are superior to single-layer techniques. Mr Harriss uses the single layer technique, and uses a variable number of sutures depending on the anatomy, rather than a large number of smaller sutures. There are plenty of people on web forums who believe that multi-layer is necessarily better, or that there is some “standard” number of sutures; this is not what the medical literature says.
The literature also does not find any benefit from carrying out sperm harvesting at the time of the operation. Since this additional procedure complicates the operation and increases its cost for no provable benefit, Mr Harriss advises against it (although it can be arranged if this is what you want).
Our commitment to evidence based surgery is borne out by our own practice in publishing audited data on vasectomy reversal success rates. Our vasectomy reversal clinic in Nottingham aims to be a leader in best practice.
