I had to stray away from medicine for this one.
Male fruit flies rejected by females turned to alcohol to drown their sorrows in a study published in the journal Science.
The male flies were placed with females that had already mated, and hence had no interest in sex. The frustrated fly fellows were provided with sugar water spiked with 15 percent alcohol, along with plain sugar water. The spurned males chose to drink the alcohol mixture 70 percent of the time, compared to their sexually satisfied peers, which chose the alcoholic mix only 50 percent of the time.
Getting their drink on might not be the best decision for a frustrated fly. A neurobiologist at Pennsylvania State University found that repeated exposure of males fruit flies to alcohol vapor put them into a sexual frenzy. The drunken Drosophila got so worked up they stopped caring what gender they were courting. Males chased each other around, serenading their beau with wings vibrating out the traditional fruit fly courtship song. However, even if the males caught up with a female, their rate of successful copulation went down with the more alcohol they had inhaled.
Female fruit flies, on the other hand, got no kick from the alcohol vapors. Mere alcohol didn’t thrill them at all. They showed little change in behavior, possibly because females do little to court males.
