Female snakes have clitorises, researchers have actually detailed for the very first time in a research study of the animal’s sex organs.
The researchers state previous research study had actually misinterpreted the organs as scent glands or underdeveloped variations of penises, in a research study that criticised the relatively minimal research study into female sex organs.
In a research study released in the journal Proceedings of the Royal Society B, the scientists discovered that snakes have 2 specific clitorises – hemiclitores – separated by tissue and concealed by skin on the underside of the tail.
“Female genitalia are conspicuously overlooked in comparison to their male counterparts, limiting our understanding of sexual reproduction across vertebrate lineages,” the research study’s authors composed.
Male snakes and lizards are understood to have hemipenes – a set of penises which are everted outside the body throughout recreation. In lots of types, hemipenes are covered in spinal columns or hooks.
The research study’s lead author and a PhD trainee at the University of Adelaide, Megan Folwell, said “a massive taboo around female genitalia” was a possible consider why snake clitorises had actually not been explained previously. “I think it’s a combination of not knowing what to look for and not wanting to,” she said.
“Trying to find it is not always the easiest thing – some are extremely tiny,” Folwell said. She first dissected the clitorises in a death adder, in which the organ forms a triangle shape “like a heart”.
“I was fortunate that the death adder had a reasonably prominent hemiclitores,” Folwell said.
The study suggests that the sex organs “have functional significance in mating” in snakes. Though more research into snake behaviour is needed, Folwell said the team theorised the hemiclitores “could provide some sort of stimulation signalling for vaginal relaxation and lubrication, which would aid the female in copulation potentially prevent damage from those big hemipene hooks and spines during mating”.
“It could also be signalling to the ovaries to ovulate and to the oviduct to potentially prepare for sperm storage,” she added.
The researchers went on to dissect 10 snakes of nine species, including the carpet python, puff adder and Mexican moccasin.

“Some of the clitorises are quite muscular and large – in say vipers – but then they’re actually thin, extended and little in some other snakes,” said Dr Jenna Crowe-Riddell, research study co-author and postdoctoral scientist in neuroecology at La Trobe University. Sizes varied from less than a millimetre to 7 millimetres.
The research study discovered the hemiclitores are consisted of erectile tissue that most likely swell with blood, along with nerve packages which “may be indicative of tactile sensitivity, similar to the mammalian clitoris”.
“Now that we know that this is here, we know what it looks like, we know there’s erectile tissue with nerves – we can’t help but think: why wouldn’t this be for pleasure?” Crowe-Riddel said. “I think it’s worth opening up those questions for snakes.”
The research study follows a research study abstract provided in the United States previously this year said that the human clitoris has in between 9,850-11,000 nerve fibers – about 20% more than the formerly extensively pointed out variety of 8,000, which apparently originated from research study performed on cows.
