dieseltaylor Posted March 24, 2011 Share Posted March 24, 2011 I have always taken the view that male homosexuality improved my choice of females. However in some countries it is a case of life and death, or imposing its legality offends other sections of socieyt. This is interesting despite the included caveats. Health 23 March 2011 Last updated at 18:03 Sexual preference chemical found in mice A chemical in the brain controls sexual preference in mice, according to scientists in China. Male mice bred without serotonin lose their preference for females, a report in Nature says. The researchers say it is the first time that a neurotransmitter has been shown to play a role in sexual preference in mammals. Experts have warned about the dangers of drawing conclusions about human sexuality. The research team first bred male mice whose brains were not receptive to serotonin. A series of experiments demonstrated that these mice had lost the preference for females shown by unmodified males.When presented with a choice of partners, they showed no overall preference for either males or females. When just a male was introduced into the cage, the modified males were far more likely to mount the male and emit a "mating call" normally given off when encountering females than unmodified males were. Similar results were achieved when a different set of mice were bred. These lacked the tryptonphan hydroxylase 2 gene, which is needed to produce serotonin. However, a preference for females could be "restored" by injecting serotonin into the brain. The report concludes: "Serotonergic signalling is crucial for male sexual preference in mice. This is the first time, to our knowledge, that a neurotransmitter in the brain has been demonstrated to be important in mammalian sexual preference." Sexual behaviour in mice is thought to be driven by their sense of smell. Professor Keith Kendrick, a neuroscientist at the Babraham Institute in Cambridge, said: "In terms of having potential relevance to understanding human sexual preference/orientation, we are of course far less influenced by odour cues in this context than mice are. "There is some very limited evidence for altered responses to selective serotonin uptake inhibitors (SSRIs) in the brains of homosexuals, but we have been using psychoactive drugs which either increase or decrease serotonin function for quite some time now, and while effects on sexual arousal, impulsivity and aggression have often been reported, no effects on sexual preference/orientation have. "At this time therefore any potential links between serotonin and human sexual preferences must be considered somewhat tenuous." It does raise interesting ethical considerations if it is found to be true. Is it like vaccination for polio good for society, or should it be a life style choice at an early age. In which case the adoption of boys by gay men might be seen in a new light. A huge can of potential worms ... but at least it is not political. : ) . 0 Quote Link to comment Share on other sites More sharing options...

I have always agreed with your opening paragraph,also... in a world with only a few choice steaks...the more vegetarians, the better for myself haha...never understood why the "meat eaters" in such a "world" would demand that everyone else eat meat also... 0 Quote Link to comment Share on other sites More sharing options...
Michael Emrys Posted March 24, 2011 Share Posted March 24, 2011 Thing is, if there aren't enough "meat eaters" among the male population to satisfy all the "meat eaters" in the female population, the girls begin adopting "vegetarianism".
