Lesbians are different from straight women

Lesbians’ brains respond differently from those of heterosexual women:

Homosexuals’ brains respond differently from those of straight men and women when exposed to sex hormones, but researchers now say the difference is less pronounced in lesbians than in gay men.

Lesbians’ brains reacted somewhat, though not completely, like those of heterosexual men, a team of Swedish researchers said in Tuesday’s edition of Proceedings of the National Academy of Sciences.

A year ago, the same group reported findings for gay men that showed their brain response to hormones was similar to that of heterosexual women.

In both cases the findings add weight to the idea that homosexuality has a physical basis and is not learned behavior.

“It shows sexual orientation may very well have a different basis between men and women … this is not just a mirror image situation,” said Sandra Witelson, an expert on brain anatomy and sexual orientation at the Michael G. DeGroote School of Medicine at McMaster University in Hamilton, Ontario.

Hehe, lesbians.
