Neuroscience of sexuality

A Swedish study shows women and gay men have the same physiological response to male pheromones, suggesting that sexual preference is more nature than nurture.

"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."
