It is the case, though, that the researchers weren't willing to say whether the scent difference was a cause or effect of being gay:

"The different pattern of activity that Dr. Savic sees in the brains of gay men could be either a cause of their sexual orientation or an effect of it. If sexual orientation has a genetic cause, or is influenced by hormones in the womb or at puberty, then the neurons in the hypothalamus could wire themselves up in a way that permanently shapes which sex a person is attracted to."

(From the New York Times coverage of the same study.)

So while I think it's interesting and possibly another indicator that being gay is something you're born with, I would hesitate to say that this study says specifically that, given that the researchers who conducted it are unwilling to conclude as much.
