How many sexes are there?
I came across mention of a theory a few years ago that argues that our theory of intersex are woefully inadequate to the evidence. This scientist argued that medical researchers have identified six different sexual variances, presumably including intersex and hypersex individuals. I'm trying to track down information about this theory of sex, and coming up empty-handed. Does anyone know more about it? Specifically, I'm interested in the sexual categories and their causes: chromosonal deformities, in utero hormonal imbalances, etc.
