Gay men have higher rat of prsn too, she says, but ’s difficult to know whether this is down to blogy, homophobia or simply feelgs of beg “different”. “This study monstrat that homosexuals of both sex show strong cross-sex shifts bra symmetry, ” says Qazi Rahman, a leadg rearcher on sexual orientatn at Queen Mary llege, Universy of London, UK.

“Paradoxilly, ’s more rmative to look at thgs that have no direct nnectn wh sexual orientatn, and that’s where this study sr, ” says Simon LeVay, a proment US thor who 1991 reported fdg differenc (pdf) a part of the bra lled the hypothalam between straight and gay men.

For example, parts of the bra volved reward and emotn are more strongly activated when straight men and lbian women look at female fac, and when straight women and gay men see male fac. But attractive fac and enticg pheromon are both related to sex, and rpons to them uld be learned over Savic’s and Ldstrom’s new study shows that the differenc extend to fundamental aspects of the bra that aren’t directly lked to sex or behavur, and that are probably fixed om ia that straight men have more asymmetril bras than gay men fs wh prev rearch.
