RIGHT HAND OR LEFT HAND? THIS EXPLAS WHY YOU'RE STRAIGHT OR GAY

The rearchers suggt beg left-hand, havg several olr brothers and havg other gay people the fay are all signifint markers. Gay men are around 34 per cent more likely to be left-hand than heterosexual men, the team saidWrg the journal PNAS, the thors wre ‘We prent evince that non-heterosexual men n be tegorized to at least four subgroups’.

Explag why mal bee gay bee they have several olr brothers, the thors say that is thought that every time a woman giv birth to a male boy, triggers an immune rponse the mother’s immune rponse creas wh each boy born, and this affects bra velopment subsequent boys, cludg that of the boy’s future sexual is a tra more mon men than women: men are 20 per cent more likely to be left hand than women.

The form of opprsn I addrs is that directed agast left-hand people, which I and my -thor, Diane Raymond, outle our book, Lookg at Gay and Lbian Life. Although numero rearchers have hypothized a blogil factor the etlogy of homosexualy, there is a lack of empiril evince. Usg nropsychologil ttg, we found an creased cince of left-hand preference (fed as non-nsistent right-hand preference) a group of 32 homosexual women.

IT’S SO GAY TO BE LEFT-HAND

The rults suggt that homosexual orientatn has a nroblogil ponent possibly related to hemispheric functnal asymmetry. The rults are nsistent wh prev reports that (1) prenatal nroendocre events are a factor the velopment of human sexual orientatn and functnal bra asymmetri, and (2) the mechanisms associated wh homosexual orientatn and related nropsychologil characteristics are different between the sex, i.

LEFT-HAND BOYS MORE LIKELY TO BE GAY, SAY SCIENTISTS

However, I fd tertg that a meta-analysis of 20 studi found that gay men are 34% more likely to be non-right hand, and gay women nearly twice as likely to be non-right hand.

The other studi ci found eher no rrelatn, rrelatn wh one sex (two studi found a rrelatn wh lbians, but not gay men, and one wh gay men but not lbians), one actually found a rrelatn wh extreme right handns, another found rrelatn both wh non-righthandns and extreme righthandns. Only one of the studi ced (asi om the 2000 meta-analysis, which arguably holds the most weight) found that gay people of both sex were more likely to be left hand, and the difference was small. Anecdotally, do seem to you that a lot of gay people are left hand, ambixtro or cross-domant?

The bra of a gay man is clearly different om a straight man's; no wonr that even their bodi functn differently. A new Canadian rearch published the journal Nropsychology and ma on gay men wh new aspects on the lk between sexual orientatn and right or left-handns.

GAYS MORE OFTEN LEFT-HAND: STUDY

Homosexuals of both genrs had been known to have a 39% creased probabily to be left-hand pared to heterosexuals. The new rearch also strengthens other fdgs showg that havg olr brothers creas the chanc for men to be gay. "The new rearch fdgs add further weight to the ia that blogil factors play a signifint role the velopment of sexual orientatn, " said Robert-Jay Green, Executive Director of the Rockway Instute, a natnal center for lbian, gay, bisexual, and transgenr rearch and public policy at Alliant Internatnal Universy.

The rearch was ma on 538 gay or bisexual men and 373 heterosexual men terviewed about their handns for 10 physil activi, but also about the number of blogil brothers.

HANDNS IS A BMARKER OF VARIATN ANAL SEX ROLE BEHAVR AND RELLED CHILDHOOD GENR NONNFORMY AMONG GAY MEN

Most subjects were right-hand, but gay/bisexual men displayed an creased chance of both left-handns and extreme right-handns pared to the straight subjects. "The number of olr brothers creased the likelihood of beg gay or bisexual morate right-hanrs only. In both non-right-hanrs and extreme right-hanrs, olr brothers eher did not crease or lowered the likelihood of beg gay or bisexual.

"If elevated extreme right-handns is an ditn of early nrovelopmental anomali, then an elevatn of this handns pattern gay or bisexual men giv addnal evince that one route to same-sex attractn is through early velopmental strsors ( the womb) or through a factor rrelated wh such strsors. "In ncln, the ma fdgs-evince of extreme right-handns gay men, along wh the moratg effect of olr brothers at both ends of the handns ntuum-potentially move forward two important rearch programs (on handns and birth orr) related to men's sexual-orientatn velopment.

"The rults of this rearch suggt there is a blogil predisposn to homosexualy among a signifint number of gay/bisexual men. Everythg mentned above about left-hand people or “lefti” is also te of homosexual or “gay” people (please re-read to reh your memory, if necsary), but when to the treatment of this group of people, our thoughts and actns are centuri behd!
