DRD4 Dopamine Gene Linked To Sexual Behavior and Fidelity

RoseTracker| Scientists are just beginning to understand how genetics and neurobiology influence a person’s sexual behavior. Justin Garcia of Binghamton University believes that the dopamine receptor D4 polymorphism, or DRD4 gene, may have high impact on our sexual activity choices. The DRD4 gene is already links to alcohol use, gambling and sensation-seeking behavior.

Garcia and his team studied 181 young adults and their DNA samples. Individuals with a certain variant of the DRD4 gene were more likely to have engaged in uncommitted sex, including infidelity and one-night stands.

Underscoring that his research is just the beginning of a long-term look into the genetics of sexual behavior, Garcia says that it’s totally possible for an individual to be looking for a long-term relationship and have a history of one-night stands. The data also suggests that it’s possible to be deeply in love with our partners and crave the dopamine rush that comes with a sexual encounter. via Science Daily
