This means that ducks can fight off unwanted or aggressive males, as they won't be able to fit their penises in with ease. Some female ducks, for example, have corkscrew-like vaginas that spiral opposite of their particular male species. For example, geese and ducks have extremely complex genitalia which protects them from unwanted mating, just like the dolphins. This was later found to be a troll page, with no scientific backing.Ĭetacean vaginas are not the only complex vaginas out there. The story originated on a Reddit forum back in 2009, when someone claimed they learned of an organic chemical that sat within the vaginal folds, which caused males to orgasm again and again as long as their penises remained within the vaginal tract. Of course, the wild story became a meme, though many people believed the information to be true. The monkey supposedly died of a heart attack. This person also claimed that scientists once used this unique secretion on a monkey penis. A Facebook post went viral, noting that female cetaceans had a unique vaginal secretion that caused males to ejaculate over and over again. Of course, there could be a few other reasons for this, such as establishing sexual dominance, a species hierarchy, or for educational purposes.Īs of now, however, we're not totally sure if it's just for fun or there are other specific reasons.īack in 2020, dolphin vaginal secretions became a hot search topic online. Just like the apes and the bonobos, dolphins have a very liberal sexual attitude. This tells us that dolphins likely have sex for pleasure. However, if it makes you feel better, dolphins are one of the few species beyond humans that have sex throughout the year. From these models, scientists could tell that females could limit dolphin penises from penetration. These scientists created digital 3D models and CT scans of these two parts to simulate how the penis would rotate. To figure it out, scientists took cetacean penises from dolphins that had died of natural causes and artificially inflated them into the female genitalia of bottlenose dolphins. Of course, scientists wanted to take it a step further by exploring how the bottlenose dolphin penis and vagina fit together during sex. What is the point of this complex shape, and wouldn't it make sex difficult?Īs we know, the whole point IS to make sex difficult for male dolphins. On the other hand, female harbor porpoises have 13 specific folds. For example, female bottlenose dolphins have vaginas with complex spiral shapes.
