Every few years, the G-spot emerges for debate. It's like the Loch Ness Monster of the female body -- there never seems to be enough conclusive evidence to prove its existence one way or another, no matter how often scientists delve into the murky depths.
New research published in the Journal of Sexual Medicine suggests the famed female erogenous zone is a myth. According to urologists at the Yale New Haven Hospital in Connecticut, who carried out the study, there is no evidence "historically or evolutionary that it should even exist".
But it's unlikely this revelation will be the last word on the subject. Ever since German gynaecologist, Ernet Grafenberg (after whom the elusive zone is named) made his discovery in the 1950s, the jury has been out on what he actually found.
According to Grafenberg, stimulating an area two or three inches inside the vaginal anterior wall will produce intense female orgasm.
His findings supported previous research by Dutch anatomist Regnier de Graf from the 1600s and even earlier evidence in an Indian text, the Kama Shastra, closely related to the Kama Sutra, that such a pleasure spot existed.
Then came the naysayers. In 2010, Kings College London surveyed 1,800 women and found that it was impossible to prove the G-spot's existence. The findings were swiftly refuted across the channel, where a committee of 1,000 French gynaecologists insisted the English had been too "pragmatic" in their research.
Co Kildare-based sex therapist Tony Duffy wonders if it really matters. "Whether it exists or doesn't, the journey can be more important than the destination," he says.
All well and good if couples enjoy the exploration, but evidence suggests that trying, and failing, to locate the erogenous zone can leave some feeling inadequate.
"Getting hung up on finding one magical place just puts you under a lot of pressure. Relax, explore," says Duffy. "Perpetuated by what they see and read in the media, people often put too much pressure on themselves. Porn especially is responsible for creating false expectations of sex in terms of how rapidly and by what means women orgasm. Or a lot of guys worry about size, when it really is what you do with it that counts."
According to Duffy, "the secret to great sex is communicating and relaxing, and remembering that the biggest sexual organ is the brain". However, he adds: "To be honest, most women would rather their partner concentrated on finding their clitoris. It definitely does exist."
