I've seen enough so that, as far as I'm concerned, there's a mountain of evidence showing that DES induces female brain development in biologically male fetuses, and, in human beings, the way this often manifests itself later in life is as MTF ->-bleeped-<-.
If one medically prescribed hormone can do this to large numbers of people and the whole thing pass completely unnoticed as far as the public are concerned, then who's to say other hormones aren't doing the same thing? Hardly anyone knows what medicines they were exposed to before birth, and, by the time you've reached adulthood, it's usually difficult or impossible to establish whether exposure took place (since medical records often no longer exist, and people's memories of what medicines were given during a pregnancy decades earlier tend to be quite unreliable). You're actually more likely to be able to find out with DES than with other hormones due to the fact that, during the 1980s, there was quite a lot of publicity about DES causing cancer, and a lot of doctors did the right thing and informed their patients who'd been given it of what happened.
So, IMO there's good reason for thinking that there could be medical hormones still in use that are continuing to cause ->-bleeped-<-. Even if by some amazing stroke of luck there aren't, the fact that ->-bleeped-<- is a kind of intersex condition and that, for many of us in the over 40s age group, it was caused by a medicine given to our mothers while they were pregnant, is something that the public should know about. I'm sure it would go a long way towards helping us gain acceptance from our families and the public at large, and I think it makes a strong case for us being given assistance with things like hormones and surgery too.
