trans | (no subject)

Genderqueer boygirlthing here, doing my term paper for biology class on transgender hormone therapy. Unfortunately I'm a wretched procrastinator and waited until the deadline for inter-library loan requests had passed, and now I'm having trouble finding full-text articles online. So does anyone have links to resources dealing with the more technical, scientific side of HRT? I probably already have enough to wring a paper out of, but I doubt the professor will be happy to learn that I only have three sources and one of them is Wikipedia. (I do have access to Medline and a good number of academic databases through the school, but most of them are only pulling up article summaries, alas.)
