It's worth giving them the link..and then telling them to get more training. The latest version (7th ed, released Sept. 2011) is really a huge change from the last version (2001). This one points to informed consent models of care as a legitimate and appropriate path. Some things around letters for surgery have changed in helpful ways, too.
http://www.wpath.org/documents/Standards%20of%20Care_FullBook_1g-1.pdfDoctors and clinics don't
have to abide by them (nor do insurance companies, alas), but we have a lot more leverage at this point than we did even last summer. The people who put the SOC together - including trans people - are some of the most experienced providers of trans health care on the planet.
And while the SOC isn't legally binding, I thought it was really powerful that the US government referred to WPATH and the SOC (earlier version) as an authoritative body. The current passport requirements allow gender marker changes
with no definition of "clinical treatment," and a prohibition against clerks asking the trans person what medical interventions they have had, or whether they have had any at all.
I'll certainly provide resources to my doctors, especially when it's in my best interest.
