"There's no other place where we so quickly divide humans
into two categories as sex. When I started doing research on the
biology of sex development, one of the things that I realized is
that the process is controlled by a series of enzymes and the
reaction may be more or less complete. It's not just two poles
where that whole process can end up. In between what we call the
ideal biological male or ideal biological female, there's a whole
range of other possibilities that don't differ from our basic
preconceptions to the extent that we have names for them or call
them a disorder. Just like with every other human trait, there are
an infinite number of possibilities." -- Gerald N. Callahan,
