DO A SHORT INX FGER MAKE YOU GAY?
Meanwhile, among the male tws, the bisexual or gay brothers had more "male-typil" hands than the straight on—ntrary to what the rearchers expected—although the difference was not signifint."Bee intil tws, who share 100 percent of their gen, n differ their sexual orientatns, factors other than geics mt acunt for the differenc," the thors wrote the study.For example, different exposure or reactns to "male hormon" (androgens)—such as ttosterone— the womb, unique to each tw pair, uld ntribute to their differg sexual orientatns, particularly for the femal."Rearch suggts that our sexualy is termed the womb and is pennt on the amount of male hormone we are exposed to or the way our dividual bodi react to that hormone, wh those exposed to higher levels of ttosterone beg more likely to be bisexual or homosexual," the thors wrote. However, is important to strs, that the evince is currently not strong enough to accurately predict whether someone is gay, straight or bisexual by lookg at the rat between their fgers."This do not allow the intifitn of someone's sexual orientatn by lookg at their fgers," Watts said.
"Some work has shown that gay men have more "male-typil" rats than straight men; other work has shown the oppose pattern; and still further work has shown no difference at all. As such, is not clear whether there is any real difference the level of ttosterone exposure between straight and gay men or how ttosterone exposure might map on to sexual orientatn differenc."Acrdg to David Puts, a profsor the Department of Anthropology at Pennsylvania State Universy, who was not volved the latt rearch, the study adds to a growg body of evince ditg that prenatal sex hormon, pecially male hormon such as ttosterone, play a role the velopment of later sexual orientatn."This is an active area of rearch, and we're learng more all of the time, but data are creasgly showg that hormon are likely to play a major role the velopment of sexual orientatn," he told Newsweek."In particular, the very large sex difference prenatal male hormon appears likely to be rponsible for the sex difference sexual orientatn (most blogil femal are attracted to mal, and most blogil mal are attracted to femal)."Male fet velop tt, and female fet velop ovari. "evince that homosexual women are exposed to more prenatal androgen than heterosexual women are; also, men wh more than one olr brother, who are more likely than first-born mal to be homosexual adulthood, are exposed to more prenatal androgen than elst sons.
They are not only claimg that the 2D:4D rat is predictive of homosexualy, but also that exposure to prenatal androgen is the root e of both fger lengths and sexual orientatn. Breedlove stated that "I have never said or thought that '2D:4D rat is predictive of homosexualy' or any other tra. As well as I n unrstand , he is claimg that "dig rats reflect prenatal androgen" but not that is predictive of homosexualy.
