Lesbians’ Brains Respond Differently Than Straight Women’s

This study offers more proof that homosexuality is determined by biology, not choice.

AP via USA Today:

WASHINGTON — 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.
