The female orgasm still baffles scientists, researchers not knowing the anatomic reason for which the sensation exists. The toe-curling reaction during intercourse has been speculated to be linked with ovulation or with the physiological impulse that encourages procreation.
The male orgasm is pretty straightforward, its role being to help the ejaculated sperm reach the egg of the female. Though some experts state that male orgasm and ejaculation are not the same thing, some men experiencing an orgasm without ejaculating, and some releasing their sperm without feeling any significant pleasure.
However, the cases in which the male orgasm and the ejaculation process don’t coincide are too rare for researchers to focus their attention on the matter.
On the other hand, the origins of women pleasure response during sexual intercourse has been circumvented the scientific community for a long time.
To this extent, a team of Yale scientists decided to tackle the eluding mystery of the female orgasm and try to determine the origin and purpose of the pleasurable physical response. Their conclusion was that it is a vestige of evolution, a sensation that went from a basic need to a pleasurable indulgence.
Currently, the orgasm has no particular role in the reproduction process so Gunter Wagner, an evolutionary biologist, teamed up with Mihaela Pavlicev and focused their attention on other mammals capable of having an orgasm.
More exactly, they selected female mammals that release oxytocin and prolactin when they reach an orgasm. In most cases, the reflex plays a significant part in the ovulation process. The orgasm helps stimulate the ovaries of the female into releasing more eggs.
Pavlicev and Wagner believe that the orgasm reflex is just a vestige of our ancestors. The ancestors of humans needing this physical trait in order to ensure their survival as a species.
Million years later, the human body considerably changed, making the female orgasm superfluous in terms of reproduction, but necessary when it comes to pleasurable sexual encounters. The authors of the study also mentioned the fact that the position of the clitoris shifted throughout our evolutionary process. Its current position is suggesting that it only plays a role in making intercourse pleasurable.
The cited study was published in the JEZ-Molecular and Developmental Evolution magazine on August 1st.
