“Women’s orgasm frequency increases with the income of their partner,” said Dr Thomas Pollet, the Newcastle University psychologist. He believes the phenomenon is an “evolutionary adaptation” that is hard-wired into women, driving them to select men on the basis of their perceived quality.

The study is certain to prove controversial, suggesting that women are inherently programmed to be gold-diggers. However, it fits into a wider body of research known as evolutionary psychology which suggests that both men and women are genetically predisposed to ruthlessly exploit each other to achieve the best chances of survival for their genes.
