A University of Rome study proves transsexuals have normal Y chromosomes. The SRY is the main sex-determining gene. AZF a, b and C are genes for male infertility. Transsexuals do not even have a smidgeon of abnormality there.

The DAX1 and androgen receptor genes were theorized to cause transsexualism since they can lead to intersex and can turn a person with a normal Y chromosome into a XY woman. Yet there is no alteration in these genes in any of the transsexuals.
