I've been looking at some of the YouTube clips from Noah Finnce.
Noah seems to have thought through the reasons against "bottom" surgery fairly sensibly.
Including an HCP at the gender clinic advising a 50% complication rate. 50%
I realise that can encompass a range of complications from a relatively mild post op infection, quickly resolved with suitable antibiotics albeit maybe a few extra days in hospital, chronic incontinence and worse. Still that is quite a compelling statistic.
For context post op infection rates for hip replacement are somewhere around 3% though this varies with different hospitals.
