Genetics may affect a person's sex drive, a new study shows.
The study -- published online in the journal Molecular Psychiatry -- doesn't claim to totally explain the science of sexual desire, or why levels of sexual desire vary. But the researchers note that their findings deserve more exploration.

At the heart of the study are different patterns in the DRD4 gene. That gene makes a protein that serves as a receptor for dopamine, a chemical messenger produced by the brain.
Sure, there has to be some level of utility in this study. The chief one could be correcting a faulty sex-drive for procreation purposes. Our knowledge of genetics may be a touch faulty itself (recessive genes, dominant genes, chromosomes, double helixes, manganese, etc.) but we’re pretty sure that a gene that totally inhibited the sex-drive would not survive many generations. We have a feeling the real goals of this study are (in no particular order): to further understanding of brain chemistry, to continue the gene map, and to perhaps figure out a way to enrich people’s lives through boosting their libido. Let’s hope that these scientists have seen The Nutty Professor. The last thing we want is for a shy researcher to turn himself into an arrogant sex maniac. Maybe Bill Clinton had this treatment in the early-90s.
