I don't have a visible adam's apple either. When I said I had a female skeleton, I wasn't just talking about size, but everything including joints, bone size ratios, skull shape, etc. Despite having kids, I've also had little body hair, sparse beard, I'm smaller than everyone in my family (including my mom) except my twin sister, I've always had soft skin, muscles of female shape and size, good hips and butt, breast growth and I'm certain my T levels have dropped significantly in the 8 years or so prior to HRT. There's enough evidence that it's undeniable that there's definitely something physically different about me than those who start off as male. I don't know about bone density because I've never been scanned. As for the voice, I don't recall mine "breaking", but it did get lower. However, with starting HRT, it seemed to reverse itself (which was odd). One strange thing is, I guess I always had small testes (if that's what they actually are) and an excess of scrotal skin. That always drove me crazy, since it loved to stick to my legs.

Anyways, hopefully the chromosome test will reveal an explanation. If not, then it's probably PAIS.
