Lesbian Mice

There is a new study out that may prove that "born that (gay) way" is actually based in science. Researchers, have discovered that serotonin (that feel-good neurotransmitter) may play a role in sexual orientation.

The study's methodology was based on:

Researchers led by Shasha Zhang at Peking University in Beijing and reviewed by Dr. Catherine Dulac at Harvard bred certain female mice that lacked either serotonin or certain neurons that release serotonin in parts of their brains.

What they found was that:

Those mice with the mutations [lower levels of serotonin] showed preferences for sniffing the head and genital areas of other female mice, as well as "try[ing] to grasp ... females by the waist before mounting on their back. ... Females displayed strong mounting preference toward the females, mounted female targets with shorter latency, higher frequency, and longer duration."

However male and female mice do not act the same under the same serotonin circumstances. Apparently male mice lacked sexual preference altogether. Feeling nerdy read the abstract and check the bar graphs here.

Seen with a different point of view, too much serotonin makes you straight!
