Are you unhappy with your ability to function sexually? Do you lack interest in sex or find it difficult to become aroused? Are you unsatisfied with your orgasms? If so, you may be genetically predisposed to have a moderate to low sex drive.
Israeli researchers published a study online in the April 18th issue of Molecular Psychiatry suggesting a link between a dopamine receptor gene and human sexual desire, arousal and function. They conclude that one gene variant found in about 60% of the population may lead to a more subdued sex drive while another, found in about 30% of the population, contributes to higher sexual desire, arousal and function.
