BRAS OF GAY PEOPLE REMBLE THOSE OF STRAIGHT PEOPLE OF OPPOSE SEX

“There is no gay gene, ” Ganna said, “but rather non-heterosexualy is fluenced by many ty-effect geic factors. Some people who have had sex wh a same-sex partner don’t nsir themselv gay and aren’t exclively attracted to people of the same sex, Bailey says.

Men the new study who said they have had same-sex partners, tend to be more exclively homosexual than women were, Ganna and lleagu found.

Bbank dataset, for example, younger people reported havg same-sex partners more often than olr people did, probably bee homosexual activy was illegal the Uned Kgdom until 1967. In the new study, the more exclively homosexual partners men had, the fewer children they had; up to 80 percent fewer children than heterosexual men. Diamond disagre that rearchers need to fd a mechanism to expla the persistence of geic variants lked to homosexualy.

GAY BRAS STCTURED LIKE THOSE OF THE OPPOSE SEX

ScienceNot Exactly Rocket ScienceThe differenc between heterosexual and homosexual people are as much the subject of fascatg science as they are a source of social bate.

A new study adds new weight to this evince by g bra-snng technology to look at the differenc between the bras of gay and straight people.

Their imag show that the bras of gay people, certa featur cludg symmetry and nnectns to the bra’s emotnal centre are more closely matched to the bras of straight people om the oppose sex. SymmetryUsg magic ronance imagg (MRI), Savic and Ldstrom showed that the bra’s two halv are almost exactly the same size straight women 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. When listeng to sounds, straight men tend to have a bias for their right ear, which both gay men and straight women lack. They also tend to outperform gay men and straight women tts of spatial awarens, where succs pends on a part of the bra – the parietal rtex – which is ually larger men than women.

From prev studi, we know that the nnectns ually lk to different areas the bras of men and women, and sprout om different hemispher -the right men, and the left was the pattern that Savic and Ldstrom saw the straight volunteers om their study, but the homosexuals showed the reverse pattern. For example, the amygdalas of gay men had more mon wh those of straight women – the two halv were well-nnected, they had more nrons projectg om the left half (as opposed to the right straight men) and the nrons nnected to the same parts of the bra that those of straight women nnectns provi some tantalisg hts about how gay and straight people differ their behavur. But straight women and gay men, the amygdala’s nnectns feed to the anterr cgulate rtex and the subllosum.

Women are 2-3 tim more likely than men to suffer om them, while gay men are also more vulnerable to prsn. Certaly, gay men, social stigma is an equally likely explanatn for higher rat of ’s very likely that the relative size of the bra’s two halv are set very early velopment.

In animals, homosexualy femal is often attributed to an overabundance of male hormon – androgens – the womb, while male homosexualy rults om a lack of the. PET and MRI show differenc cerebral asymmetry and functnal nnectivy between homo- and heterosexual subjects. For at least 20 years, nroscientists have been tryg to disver whether there are specific anatomil differenc between heterosexual and homosexual men and women.

An early post-mortem study found that a small regn of the anterr hypothalam was smaller homosexual men than heterosexual men, and no different om heterosexual women. Overall, the specific bra regns homosexual mal tend to be siar to heterosexual women (more female‐typil), while the same bra regns homosexual women tend to be siar to heterosexual men (more male‐typil).

STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR

Many of the early imagg studi were limed by small sample siz and did not clu female, both heterosexual and homosexual, parison groups. Essentially, the differenc bra anatomy that distguish heterosexual mal and femal were prent, however they were ls pronounced when parg male and female homosexuals.

The bra regn that showed the most nsistent sexual orientatn‐related differenc both male and female homosexuals was the lre sulc. Geic factors that are associated wh variatns some rtil stctur showed oppose effects on rtil volume male vers female homosexuals who reported same-sex sexual behavrs. In other words, the bra regns of tert this study beme larger homosexual femal and smaller homosexual mal, as pared to their heterosexual unterparts.
