MEN WH OLR BROTHERS ARE MORE LIKELY TO BE GAY, STUDY SUGGTS

Men wh olr brothers are more likely to be gay, acrdg to a study published Wednday the journal Proceedgs of the Royal Society B.

HAVG OLR BROTHERS CREAS MEN’S LIKELIHOOD OF BEG GAY

This new report builds upon prev rearch regardg male birth orr and homosexualy, though there is still no cisive ncln as to why there’s a lk between the cross-analyzg data om 10 scientific studi wh more than 5, 000 subjects, rearchers found that men wh olr brothers were 38 percent more likely to intify as gay.

”The study, which pared the probabily of the youngt brother a two-son fay beg gay as pared to the olst son, did not clu female subjects, as prev rearch has tablished that women do not fluence the sexual orientatn of their younger siblgs, acrdg to this study did not terme a ncrete reason for the rrelatn between a man havg an olr brother and intifyg as gay, Blanchard said that “pots toward the need for more rearch on the 'maternal immune hypothis'” — a theory Blanchard troduced 1996 that suggts that a mother is exposed to “male-specific substanc” durg pregnancy wh or the birth of a son. Acrdg to proponents of the theory, the mother’s immune rponse is changed durg the pregnancy of a boy, creasg the likelihood that a subsequent male child would be gay.

Earlier studi have noticed that gay men often have olr brothers. If you’re a guy wh an olr brother, there’s an creased chance you’re gay.

BOYS WH OLR BROTHERS MORE LIKELY TO BE GAY, STUDY SAYS

The rearchers say that if their fdgs n be replited, we may know at least one of the blogil reasons some men are gay.

A 2006 study showed that wh each brother, the chance that a man will be gay go up by about a third, but the rearchers didn’t terme why that was. They found the hight ncentratn of antibodi to the prote women wh gay younger sons who had olr brothers, pared wh women who had no sons or who had given birth to only heterosexual boys. One found that a man’s chanc of beg gay creased even if he was raised apart om his olr brother.

DO HAVG OLR BROTHERS INCREASE MEN’S CHANC OF BEG GAY? HERE’S WHAT THE STUDI SAY

The rearch do not give a blogil explanatn for why some men may be bisexual or may not be attracted to anyone at all, nor n give a blogil explanatn for gay only children, gay olst sons or women who are attracted to women. Bailey’s latt paper, published this month the journal Nature Rearch, looked at people’s genom and found several regns wh sgle-letter DNA chang that were more mon among gay men than straight men and may be relevant to the velopment of sexual orientatn. In the first-ever laboratory study of mothers of gay men, the rearch was prompted by more than two s of statistil data examg the 'olr brother effect' which shows that blogil olr brothers—but not olr sisters—crease the odds of homosexualy later-born mal.

The study, "Male Homosexualy and Maternal Immune Rponsivy to the Y-Lked Prote NLGN4Y, " was published Monday, Dec. The current study adds to the growg scientific nsens that homosexualy is not a choice, but rather an nate predisposn.

THERE IS NO ‘GAY GENE.’ THERE IS NO ‘STRAIGHT GENE.’ SEXUALY IS JT PLEX, STUDY NFIRMS

The team of psychologists and immunologists tted 16 women wh no sons, 72 mothers wh heterosexual sons, 31 mothers of gay sons wh no olr brothers, 23 mothers of gay sons wh olr brothers, and a ntrol group of 12 men. The team found that mothers of gay sons, pecially those wh olr brothers, had signifintly higher antibody levels to both forms of NLGN4Y than did the ntrol sampl of women, cludg mothers of heterosexual sons.

STUDY LKS GAY MEN TO OLR BROTHERS

However, the psychologist utns that the effects are most and the likelihood of a male child beg born gay is still small—even if they have multiple male siblgs.

STUDY SUGGTS MAL WH OLR BROTHER MORE LIKELY TO BE GAY

Study nfirms lk between the number of olr brothers and creased odds of beg homosexual (2017, December 12).

New rearch found that havg an olr brother creas men’s chanc of beg gay, acrdg to a study published Wednday the journal Proceedgs of the Royal Society B. The fdgs om German and Canadian scholars showed that men wh olr brothers have a 38% higher likelihood of beg homosexual than men who don’t have an olr brother. “[Olr] brothers crease the probabily of homosexualy later-born mal, ” read the study’s abstract.

HAVG OLR BROTHERS INCREAS A MAN'S ODDS OF BEG GAY

The fdgs also showed that the more olr brothers a man had, the higher the likelihood he would be gay. Havg three olr brothers doubled a man’s chanc of beg gay, acrdg to the rearch. The study also found a rrelatn between mothers givg birth to homosexual mal and havg more children, as pared to moms of straight mal havg fewer children.

“[Mothers] of homosexual mal produce more offsprg than the mothers of heterosexual mal, ” the rearchers wrote.

“The fascatg study timat that havg an olr brother creas the odds of beg gay by 38 percent, supportg the ia that a mother’s immune rponse to havg a male child fluenc subsequent boys, ” Universy of Cambridge profsor and statistician David Spiegelhalter told the Daily Mail. Ined, no particular pattern of siblgs, their genr or their age appeared to terme whether a female would be gay.

HAVG MORE OLR BROTHERS CREAS MEN’S ODDS OF BEG GAY, STUDY NFIRMS

“Gay men have, on average, a greater number of olr brothers than do heterosexual men, a well-known fdg wh sexual science, ” wrote the rearchers om Canada’s Brock Universy, the Universy of Toronto, and Harvard Medil School a study published the scientific journal uld expla such a phenomenon? “This explanatn poss that some mothers velop antibodi agast a Y-lked prote important male bra velopment, and that this effect be creasgly likely wh each male gtatn, alterg bra stctur unrlyg sexual orientatn their later-born sons, ” wrote the study thors, who also strsed that more rearch needs to be done on the issue to nfirm their Universy’s Anthony Bogaert, one of the lead study thors, further emphasized the rearch is not meant to suggt that beg gay is some sort of illns or geic fect.
