For those visitors who have been flocking here from Pharyngula on the ScienceBlogs site complex, welcome!
Some of my more recent posts on Intersex, Transsexuality and Biology are:
BiGender and the Brain, Sex and the Brain, Square Peg, Round Hole, Mommy, Don't Take me There, and Transsexual Causation, the American Psychiatric Association, and Interpol. But you'll find a lot more, going through the archives. Plus "Blue Suede Shoes" in the original Klingon, thoughts on Euler's equation, and a miscellany of subjects. Quite a bit on TS and IS human rights too, or rather, the lack thereof. My experience has certainly been educational.
My own peculiar and ongoing story is described at Year Three and related posts.
