Lack of excitation of Lesbian brain for pheromones?

link from newscientist
LOL
there's no evidence for pheromones in humans as yet, but this study is damn interesting cos it basically says that a steriod called AND derived from progesterone and found in men's armpit sweat is able to stimulate the brains of heterosexual women in areas other than the smelling region. BUT in lesbians it doesn't happen.
you would would think so what if you use women 'pheromone' on lesbains? they used EST derived from oestrogen (fd in pregnant women urine) but it has no effect on lesbian brains either..

haha my take is
1) lesbian brains have faulty wiring
OR
2) they used wrong 'pheromone'
I mean PLEASE? How attractive can a pregnant woment be? How attractive is urine smell?


UPDATE: reported in science as well... darn better not sweat near gay men..
