The most common gender affirming surgery is breast augmentation -- in cis (non-trans) women.

The regret rate is around 20%.

Gender affirming surgeries in trans people have around a 1% regret rate.

Guess which people need approval from a mental health provider...

That might suggest requiring such approval is quite effective in lowering the regret rate...🤔

@sibrosan One thing we know is that regret rate over the years has not changed, despite gatekeeping being reduced (albeit not eliminated). I.E. it’s easier to get trans-related surgery now than it was 30 years ago, yet regret rate has not gotten higher.
@joelle @sibrosan it certainly hasn't got easier in the last 25 years. But the numbers seeking it are up.
A comparison with women's elective cosmetic surgery is flawed though. Better to compare regret rates with those who had medically approved surgery (e.g. on the NHS).
The other problem is that trans patients may not regret having the surgery (as the need is real) but could still be unhappy as to how well it was done, which is what those who have cosmetic surgery are largely concerned with.
