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

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).

Essentially, the differenc bra anatomy that distguish heterosexual mal and femal were prent, however they were ls pronounced when parg male and female homosexuals. 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. 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.

STUDY SAYS BRAS OF GAY MEN AND WOMEN ARE SIAR

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. 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.

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.

BRAS DIFFERENT GAY, STRAIGHT PEOPLE

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.

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. For stance, early studi reported an almost two-fold volumetric crease of the suprachiasmatic nucls of the hypothalam16 but twice smaller volum of the third terstial nucls of the anterr hypothalam (INAH-3) homosexual (HoM) relative to heterosexual men (HeM) and no volumetric differenc the INAH-3 between heterosexual women (HeW) and HoM17.

A GAY MAN’S BRA LOOKS A LOT LIKE A STRAIGHT WOMAN’S BRA

Comparg the regnal rtil thickns and subrtil volum of heterosexual and homosexual mal revealed smaller thalam volum and thner right orboontal and right visual rtic HoM20. In another voxel-based morphometry (VBM) study on sexual orientatn, ls gray matter nsy was observed the ventral cerebellum, the left ventral premotor rtex, and the temporo-basal rtex homosexual relative to heterosexual women22.

Furthermore, homosexualy seems to be associated wh ls distct cerebral sexual together, although extant fdgs suggt that human sexual orientatn is associated wh bra morphology, the heterogeneo and limed number of studi preclus a thorough unrstandg of the shared and distct nral signatur of sexual orientatn men and women.

MethodsParticipantsMRI data of 37 men (21 homosexual men = HoM; 16 heterosexual men = HeM) and 37 women (19 homosexual women = HoW; 18 heterosexual women = HeW) entered the analys (see Supplementary Table 1 for sample mographics; N = 74). Participants were reced through universy bullet boards, Lbian, Gay, Bisexual, Transgenr, and Queer or Qutng + (LGBTQ +) anizatns Aachen, Cologne and surroundg areas, and by word-of-mouth remendatn. All participants were asked to dite their sexual orientatn at the time of measurement g a 1 to 4 sle rangg om (1) exclively homosexual, (2) predomantly homosexual, (3) bisexual, or (4) heterosexual.

Altogether, 19 homosexual men and 15 homosexual women intified as exclively homosexual, while two homosexual men and four homosexual women intified as predomantly homosexual.

Clter 2: Pre- and postcentral gys (MNI − 41, − 18, 66)Heterosexualy > homosexualy (whole-sample) analys related the pre-/post-central gys to actn executn, speech, perceptn, and somthis functnal domas, and to paradigms cludg fger tappg, drawg, flexn/extensn, and reward. DiscsnIn this study we vtigated rti-subrtil gray matter volume differenc homosexual and heterosexual dividuals to addrs the sparse and heterogeneo fdgs on morphologil bra differenc associated wh sexual orientatn. In le wh our hypoth, we found that, relative to homosexual participants, heterosexual dividuals had signifintly higher GMV the thalam and precentral gys.

Breakg the rults down by blogil sex, highlighted that hetero- vers homosexual women (HeW > HoW) showed larger GMV the precentral gys, while the reverse ntrast (HoW > HeW) revealed larger GMV the putamen. In heterosexual and homosexual dividuals, the meddorsal thalam was more activated by fac of the preferred sex relative to fac of a ls sired sex, pennt of the observers’ blogil sex or sexual orientatn45. While ngently suggtg that hypothalamic activatn has downstream effects on visual perceptn likely impactg the selectn of sexual partners46, prev fdgs also support a role of the thalam signalg sexual reward47 and aroal among homosexual and heterosexual thalam has numero reciprol rti-thalamic nnectns wh reward and sensory-motor regns49.
