On the Science of Changing Sex

When the Numbers Add Up…

Sometimes, when one spots numbers that seem to be awfully familiar, they cause us to wonder.  Well, I think I spotted either an amazing random coincidence, or a basic connection between the incidence of autogynephilia and autoandrophilia in the general population and the incidence of potential gender dysphoria found in teenagers.  Check out these numbers.

From the Sumia study  0.5% girls compared to 2.2% of the boys had indicated such potentially clinically significant dysphoria.  Note that this is indeed potential, not clinically significant distress.  While in the Langstrom study 2.8% of men and 0.4% of women reported at least one episode of transvestic fetishism.

Again 0.5% vs. 0.4% for natal females and 2.2% vs. 2.8% for natal males.

So, random coincidence?  Or underlying correlation?  We need further study.  But I’m willing to put a high confidence estimate that this reflects that the GIDYQ-A is picking up on the connection between autogynephilia / autoandrophilia and mild gender dysphoria.
