Now, we have scientists in China discovering that the chemical serotonin controls the sexual preference of mice. Males without the chemical in their brain are no longer attracted to females and are likely to be attracted to male mice. Good lord! What's next?

The researchers said that it is the first time that a nuerotransmitter has been shown to play a role in sexual preference in mammals, however  many experts are warning that is is dangerous to draw conclusions about human sexuality.

The tests were carried out by a team of scientist that bred mice whose brains were not receptive to serotonin, several tests showed that these mice were no longer atrracted to females but the attraction to females could be "restored" once the chemical was injected into the brain.

I really think it's great science is looking for "reasons" for certain things but why do they care so much about sexual preferences? What is this going to change? If anything, I think these kind of experiments do more harm than good. So what if it was all about a chemical in your brain that makes you "gay" would we now have a "cure" for it? I am all for medical and scientific breakthroughs but people need to face the facts some men just like cock! GET OVER IT!

What do you all think? Medical breakthrough or rubbish?
