Hi, an interesting hypothesis.
I personally began my full time transition just over 7 years ago and I lived quite androgenously before that.
I have also been or still am a mamber of several support groups both in the UK and in France. My membership of these groups began many years before I went full time. I therefore feel able to give some expert validity
It has been my experience that most don`t survive but some do. The variation and reasons are as far as I know an unknown statistic.
So the results of this question lack any construct or expert validity and are just a fun
.
