Researchers at King’s College London have presented new evidence that the fabled G-spot is pure fantasy …so to speak.

The team, headed by Andrea Burri and Tim Spector, interviewed 900 pairs of female twins from all adult age groups. Participants were asked to declare if they possessed the illusive erogenous zone. Most of the women, 56%, claimed that, yes, they do indeed have a G-spot. However, there was no greater correlation between the responses of genetically identical twins than between non-identical twins. One might expect a strong agreement between individuals of near-identical physiology, but this is not the case. This discrepancy, say the researchers, suggests that the G-spot is not real. It is a psychological or social construct rather than a tangible pleasure zone.

The findings are drawing criticism. The study relies on self-reporting rather than any physical measurement (which, understandably, would be difficult to effect). Plus, presence of this favourably innervated region might rely on non-genetic factors such as diet, exercise and sexual history. It’s all a bit of a fumble in the dark, really. Millions of women claim the zone exists, yet no strong evidence has ever been found to back it up. Should we believe the latest findings? Should we care? Did Henry miss a trick by not calling his blog the Gee Spot? And how might we design a more rigorous experiment to probe the sexual enjoyment of twins? (Actually, don’t answer that last one.)
