Previous studies suggest sex plays an important role in social bonding among dolphins, as seen in other social species.

The researchers discovered that the skin under the clitoral hood contains “bundles” of nerves that may increase sensitivity and the potential for pleasure, as has been found in the human clitoris. Their findings were published in Experimental Biology. They said the structure of the tissue suggests the dolphin clitoris may expand, for example, in response to stimulation.

NASA gets closer to the sun than ever before in latest probe “Studying and understanding sexual behaviors in nature is a fundamental part of understanding the animal experience and may even have important medical applications in the future.”īy Alison Bosman, Earth.Breakthrough for 'splaceplane' that can rocket from NYC to London in 1 hour “This neglect in the study of female sexuality has left us with an incomplete picture of the true nature of sexual behaviors,” said Professor Brennan. In fact, even the human clitoris wasn’t fully described until the 1990s. This research helps to remedy the situation that the general anatomy of the clitoris in female mammals has often been inadequately or inaccurately described in the past, and the deep structures of the organ have historically been overlooked. Some were larger than half a millimeter in diameter.” Also, the size of the nerves in the clitoris body was very surprising. “Since the entire pelvis of dolphins is so different to humans, it was surprising to see how similar the shapes were. Overall, Professor Brennan says that the erectile bodies in dolphins are “surprisingly similar” to the shape of the erectile bodies in humans.
They also found genital corpuscles much like those previously described in the human clitoris and penis tip, which are known to be involved in the pleasure response.

Their studies also show that the clitoris body has large nerves and many free nerve endings right underneath the skin, which is much thinner there than in the adjacent skin. The erectile tissue changes shape as dolphins mature, which suggests that it acquires a function that is associated with being an adult. “Just like the human clitoris, the dolphin clitoris has large areas of erectile tissue that fill up with blood,” said Professor Brennan. Their results supported the hypothesis that female dolphins have a functional clitoris that helps to make the sexual experience pleasurable. They analyzed the shape and configuration of erectile bodies within the organ, as well as the nature and pathways of nerves that ran through the tissues.
This has led to the hypothesis that dolphins may be sexually active not only in the name of reproduction, but also because this brings them pleasure.īrennan and colleagues examined the clitoris from each of 11 female dolphins that had died naturally. “We knew that dolphins have sex not just to reproduce, but also to solidify social bonds, so it seemed likely that the clitoris could be functional.”ĭolphins are among the few mammalian species that are involved in sexual behavior at times when they cannot conceive. “Every time we dissected a vagina, we would see this very large clitoris, and we were curious whether anyone had examined it in detail to see if it worked like a human clitoris,” said study first author Professor Patricia Brennan. The position of the clitoris in a dolphin’s vagina would make stimulation during copulation likely, and thus the researchers questioned whether the structure of the organ in dolphins would reveal evidence that it functions to produce sensations of pleasure. The researchers became curious about the function of the clitoris while studying the evolution of vaginas in dolphins.
