I was taught that intersexual was the existence of both female and male organs in the same body. As such it is attributable to complete and partial hermaphrodites, and to some chimeras, but would not include those with AIS, Klinfelter's and the mosaics, Turner's and the mosaics, mosaics in general, Lubs syndrome. However it may include fetal estrogenization and androgenization. It would also tend to exclude hypospadius. Now all of these regardless would tend to fit on the transgender spectrum. I myself am a chimera, 80% XX: 20% XY and an MTF. I do have some unusual physiological attributes, and responses to hormones; seems I have the AR gene on the 20% XY, but I would not be defined as inter-sex, but simply a transgender on the spectrum.
