MANY studies have been carried out on the subject of transsexuals (TS), but one question remains – is transsexualism a biological occurrence or is it just a matter of cross-dressing?
Professor Dr Teh Yik Koon of National Defence University of Malaysia, who has been studying transsexual issues for more than a decade, believes it is much more than individuals entertaining their alter egos.
She says various research findings have shown that transsexualism is a medical condition.
She cites an article released in 2000 by Frank P.M. Kruijver, Jiang-Ning Zhou, Chris W. Pool, Michel A. Hofman, Louis J.G. Gooren and Dick F. Swaab titled Male-to-Female Transsexuals Have Female Neuron Numbers in a Limbic Nucleus.
The researchers concluded that in TS, sexual differentiation of the brain and genitals may go into opposite directions and point to a neurobiological basis of gender identity disorder.
Their study revealed that the number of neurons in the bed nucleus of the stria terminalis (BSTc) of male-to-female TS was similar to that of the females (P > 0.83). In contrast, the neuron number of a female-to-male TS was found to be in the male range.
Teh says those who do not want to accept that it is a biological occurrence are those who believe that their religion forbids it and there is no such thing as transsexualism.
