Sexual orientation is a biologically fixed attribute, research confirms

by FRANCESCA VELLA

British and Swedish researchers have published the best evidence yet that one's sexual orientation is a biologically fixed attribute, but Gabi Calleja from the Malta Gay Rights Movement (MGRM) said, in effect, that knowing why a person is gay or straight is not really necessary, or even desirable.

In a paper published in the Proceedings of the National Academy of Sciences USA (PNAS), two researchers, Ivanka Savic and Per Linström from Karolinska Institute in Stockholm, explain that the research is particularly interesting in that it "contributes to the ongoing discussion about sexual orientation by showing that homosexual men and women differed from the same-sex controls".

Welcome. Thank you for reading.

Zoe Brain's found the study as well.

BiGender and the Brain
Gender-Typical Behaviour Patterns, Sexual Orientation and Gender Identity are set in Neurology.


A E Brain, Blogspot

"Cross-Gendered (CG) Sexual Orientation is an unsubtle effect, and often associated with cross-gendered behaviour patterns in young children. It appears to be set by pre-natal hormone influences.

CG Gender Identity is also set by pre-natal influences. The effects appear later, and the tell-tale neurology appears after Gender Identity is formed. But the pattern that dictates the later neurological development is just as pre-ordained. It is a more subtle effect that sexual orientation, and many people are essentially Bi-Gendered, and would be able to function in either a male or female role, as circumstances dictate. Relatively few are strongly gendered, but for those that are, it's unchangeable. Just as CG sexual orientation is strongly correlated with CG behaviour in children, CG gender identity is universally(?) associated with CG patterns of thought in children."
