Among non-human mammals, exposure to androgens durg cril perds of velopment leads to gynephilia (attractn to femal), whereas the absence or low levels of prenatal androgens leads to androphilia (attractn to mal). However, humans, retrospective markers of prenatal androgens have only been associated wh gynephilia among women, but not wh androphilia among men. Here, we asked whether an direct ditn of prenatal androgen exposure, 2D:4D, differs between subsets of gay men leated by anal sex role (ASR). ASR was ed as a proxy for subgroups bee ASR groups tend to differ other measur affected by bra sexual differentiatn, such as genr nformy. First, we replited the fdg that gay men wh a receptive ASR preference (bottoms) report greater genr nonnformy (GNC) pared to gay men wh an sertive ASR preference (tops). We then found that Tops have a lower (male-typil) average right-hand dig rat than Bottoms, and that among all gay men the right-hand 2D:4D rrelated wh GNC, ditg that a higher (female-typil) 2D:4D is associated wh creased GNC. Differenc were found between non-exclive and exclive same-sex attractn and GNC, and ASR group differenc on dig rats do not reach signifince when all non-heterosexual men are clud the analys, suggtg greater heterogeney the velopment of non-exclive same-sex sexual orientatns. Overall, rults support a role for prenatal androgens, as approximated by dig rats, fluencg the sexual orientatn and GNC of a subset of gay men.

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. "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.

"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. Some scientists believe prenatal sex hormon are also part of the puzzle of homosexualy and that a high level of ttosterone may wire the bra for attractn to the same sex.
Intrigugly, rearch shows that a prenatal ttosterone level is most strongly lked to homosexualy women, acrdg to an article the Archiv of Sexual Behavr. Some studi have shown hypermascule fger length gay men, while other studi show the oppose, a female-like fger pattern.

Still, even if prenatal ttosterone is a factor homosexualy, 's unlikely to be the only element. "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.
