The existence of female orgasms has prompted discussions for centuries as they don’t have any actual reproductive function. But now researchers claim that the origins of female sexual arousal date back to the time when prehistoric women needed to be stimulated so that they could release an egg for fertilisation.
Recent studies suggest that in the past, our female ancestors only ovulated after being stimulated by their male partners just before or during sex. This is something that still occurs among several species of mammals like rabbits, ferrets, camels, and cats.
However, women’s bodies over hundreds of thousands of years have now evolved to ovulate by themselves once in a month. Professor Gunter Wagner, who is an expert on Ecology and Evolutionary Biology at Yale University, claims that in the past all female mammals ovulated after experiencing an orgasm, according to a report Daily Mail. But gradually, some species – such as humans, dogs, cows, and rats – evolved to ovulate by themselves during cycles.
Professor Wager’s work, which has been published in the journal JEZ-Molecular and Development Evolution, focuses on the hormones released by different female mammals during sex. He and his team found that most of these creatures released ‘feel-good’ hormones like prolactin and oxytocin that helped trigger ovulation in many cases. This led them to the conclusion that in the past, ovulation was always triggered by an orgasm.
