“Female genitalia were assumed to be simple and uninteresting,” Heinen-Kay said. Historically, researchers have focused on male genitalia, driven by prejudice toward male subjects, prejudice against female choice in sexual selection and the fact that it can be easier to study something that sticks out. “This research challenges that notion.”Īnd learning more about the anatomy of marine mammals’ genitalia has clear implications for their survival, Mesnick said: “The more we know about the social behavior of these animals, the better we’re able to understand their evolution and help use that to manage and conserve them.” “A lot of people assume that humans are unique in having sex for pleasure,” Justa Heinen-Kay, a researcher at the University of Minnesota who was not involved with the paper, wrote in an email. She added, “It took a team of brilliant women,” referring to two of the authors. “The only thing that surprises me is how long it has taken us as scientists to look at the basic reproductive anatomy,” Sarah Mesnick, an ecologist at NOAA Fisheries who was not involved with the research, said, speaking of the clitoris. The findings come as little surprise to scientists who research these dolphins. Anything is possible, and, as new research suggests, probably pleasurable for swimmers of both sexes.Īccording to a paper published on Monday in the journal Current Biology, female bottlenose dolphins most likely experience pleasure through their clitorises. Copulation lasts only a few seconds, but social sex, which is used to maintain social bonds, can last much longer, happen more frequently and involve myriad heterosexual and homosexual pairings of dolphins and their body parts. Common bottlenose dolphins have sex frequently - very likely multiple times in a day.
