I have serious questions about what these doctors think they’re doing telling these discouraging stories without proof

Quite, wildlyparenthetical. I find it much easier to conceive of rumour-created fear of a list designed to make intersex people’s interactions with doctors more difficult, than to accept that any Government agency would place any stock in a register whose data included anything of so little value as PBS scripts. Cops, doctors and policymakers might be bigoted and ignorant, but the people who design criminal databases know more about how to collect useful data.
For the record it’s really quite difficult and onerous to be on these kinds of Registries in Australia; you generally have to be sentenced by a court for certain kinds of offences, and the requirements often involve having to regularly report to the Police. The NSW Child Protection Register, for example, only lists people who have committed offences against children, and the NSW Working With Children check applies only to “prohibited persons” who have been sentenced by a court. You don’t just wind up on some kind of pervert’s blacklist without your knowledge.

The issue is more that, as Liam says, it’s not clear that the Sex Offender Registry exists. The only evidence for it seems to come from those whose doctors have prescribed them the drug, and warned them that this is part of the deal. The stories about this have circulated far and wide: there’s a number of people in the thread at Zoe’s who have been told they have been added to this list, and there’s a slightly different version of this story written up as part of HREOC’s Sex and Gender Diversity Report (http://www.hreoc.gov.au/genderdiversity/consultation_report2008.html#6). Some say they’ve been denied permission to Work With Children; others say they’ve had no such issues. If the list exists, I wouldn’t be completely shocked if they used something as odd as scripts entered into the PBS to add people to it. If it doesn’t, and it’s hard to find evidence outside of ‘my doctor warned me’, then I have serious questions about what these doctors think they’re doing telling these discouraging stories without proof, and the effect they have on their trans or intersex patients.

I think WP’s point about doctors being involved in this aspect of scaremongering could be an important one. It’s also possible, though I’d like to think (hrm) it would be hard to believe with doctors who are specialising in trans and intersex issues, that some doctors haven’t clicked past the cancer/deviancy indication set to find the one for androgenisation.
