QuoteGene linked to transsexualismSYDNEY: The first genetic link to male-to-female transsexualism provides new evidence of its biological nature, say Australian researchers."There is a social stigma that transsexualism is simply a lifestyle choice, however our findings support a biological basis of how gender identity develops," said Vincent Harley a geneticist from Prince Henry's Institute in Melbourne and co-author of a new study detailing the find.Gender identityGender identity, an inner feeling of being male or female, is usually identified at an early age. Transsexuals, however, identify with the sex that is opposite to their biological sex.Early theories as to the cause of transsexuality suggested that it could stem from childhood trauma, but more recent research has pointed to family history and a possible genetic aspect. A study released earlier this year by researchers at the University of Vienna, Austria, hinted at a gene that may be involved in female-to-male transsexualism.The new study, published today in the journal Biological Psychiatry, builds on previous research that highlighted some similarities in the brain structures of women and male-to-female transsexuals.For the study, Harley and his team took DNA from 112 male-to-female transsexuals and 258 non-transsexual men. They looked at the sequence of three genes known to be involved in the action of sex hormones, and found that some male-to-female transsexuals carry a different form of a gene, called an androgen receptor, which modifies the body's response to testosterone.Androgen receptorThe researchers found that, on average, the form of the gene found in the transsexual group had a larger number of repeats of a short, repetitive sequence of DNA - making the gene significantly longer than the form found in the control group of non-transsexual men.Though the researchers admit that the average difference in the length of the gene between the two groups was small, they said that the size of the study population was limited by the rarity of transsexualism. Nevertheless, "we think that these genetic differences might reduce testosterone action and under-masculinise the brain during foetal development," said co-author Lauren Hare, a geneticist from Monash University in Melbourne.

Quote from: toxicblue on January 06, 2012, 12:13:11 AMI've also heard that a possible cause of transsexualism is before someone is born and their brain gets in contact with hormones, boys often have a high amount of testosterone and girls have a small amount. If a boy has a small amount or a girl has a large amount, they are more likely or act like the opposite gender, be gay, or become transgender. I read about this in a book called The Riddle of Gender.

Quote from: Lyra Dash on January 08, 2012, 04:45:21 PMI do know that my index fingers are very slightly longer than my ring fingers and that my hair spirals counterclockwise, both of which are indicative of a high exposure to estrogen in the womb. I think I got a Y chromosome but then my mom's body developed me as it would have a girl, though maybe to a lesser extent, and I suppose that could have played a key role.

Quote from: Sandy on January 08, 2012, 05:02:17 PMBut the bottom line is, if you knew what caused it, what would you do about it? Would having an explanation help your mental outlook? Possibly not. You are because you are. It is what it is. To search for a reason in the end is fruitless.-Sandy
