The brains of gay men and women look like those found in heterosexual people of the opposite sex, research suggests.
The Swedish study, published in the Proceedings of the National Academy of Sciences journal, compared the size of the brain's halves in 90 adults.
Gay men and heterosexual women had halves of a similar size, while the right side was bigger in lesbian women and heterosexual men.
A UK scientist said this was evidence sexual orientation was set in the womb. . . .
Dr Qazi Rahman, a lecturer in cognitive biology at Queen Mary, University of London, said that he believed that these brain differences were laid down early in foetal development.
"As far as I'm concerned there is no argument any more - if you are gay, you are born gay," he said. . . .
