Scientists have found that orgasm has become a “useless” phenomenon for evolution, a kind of relic of the past..
Female orgasm turned out to be a kind of atavism from the point of view of evolution - in the past it promoted ovulation and the development of germ cells during mating, and now plays no role, say scientists in an article published in JEZ-Molecular and Developmental Evolution.
“In the past, our colleagues focused on what is in human biology today and the features that could change, and almost did not try to understand how this feature - an orgasm - could have arisen in the course of evolution,” said Gunther Wagner ( Gunther Wagner) from Yale University (USA).
Scientists and philosophers since antiquity ponder why women experience pleasure during sex. From the point of view of evolution, such a feature of the body does not make any sense - it does not help women to become pregnant more often and produce more children.. Moreover, the females of our closest relatives leading a monogamous lifestyle - gibbons - do not experience an orgasm in principle, which casts doubt on the “social” role of this peculiarity of the female reproductive system..
Wagner and his colleague Michaela Pavlicheva (Michaela Pavlicev) tried to reveal the role of orgasm, drawing attention to what actually happens to the woman's body when this condition occurs, and comparing it with how the bodies of female monkeys and other mammals behave.
The main biological feature of orgasm, as the scientists explain, is the release into the blood and a surge in the concentration of a number of hormones, including oxytocin, the hormone of family happiness, and prolactin, the hormone of motherhood, which prepares the woman’s body for the development of the embryo and child. Something similar, as Pavlicheva and Wagner discovered, occurs in the body of females of other mammalian species - a similar release of prolactin and oxytocin in their body occurs at the time when they begin to ovulate.
Ovulation in women, unlike animals, goes on its own and does not depend on the season or other important factor that causes ovulation in females of many other mammals - the smell or the type of a suitable male.
The presence of such features in the sexual behavior of females in the most ancient species of mammals that exist today, argues in favor of the fact that ovulation at the sight of a male appeared earlier than the cyclical ovulation of modern women. For this reason, it is likely that a similar process was the “grandfather” of modern orgasm during sex, the meaning of which disappeared after the women's body switched to latent cyclic ovulation, which does not allow the potential sucker to guess whether it is ready to mate or not..
According to the authors of the article, this is supported by the fact that the clitoris “moved” as man evolved from the inner part of the female reproductive system to his current position, which reduced the likelihood of “accidental” triggering of this reflex during sexual intercourse.
Today, all these changes have lost their meaning, since the appearance of men today is not affected by the process of ovulation, and the orgasm has become “useless” for evolution by a phenomenon, a kind of relic of the past.
