The elusive female G-spot has mystified women - and men - for years. Now research suggests the ‘holy grail’ of female orgasms may not even exist.

After reviewing 100 studies conducted over the past 60 years, scientists found there is no conclusive evidence to support the existence of the erogenous zone. They suggest its popularity is a product of hype, fuelled by the pornography and sex therapy industries.

Lead researcher, Dr Amichai Kilchevsky, a urologist from the Yale-New Haven Hospital in Conneticut said: “Objective measures have failed to provide strong and consistent evidence for the existence of an anatomical site that could be related to the famed G-spot.

“Lots of women feel almost as though it is their fault they can't find it. The reality is that it is probably not something, historically or evolutionarily, that should even exist.”

After analysing results from tissue biopsies, Dr Kilchevsky said that although some studies did report more nerve endings in the ‘G-spot area’, others found fewer in the same place, making the results inconclusive.

The findings, published in the Journal of Sexual Medicine, support a previous study from King’s College, London, in January 2010.

The British researchers studied 1,800 women, all of whom were either identical or non-identical twins. If the G-spot did exist the genetically identical twins would be expected to both report having one. Therefore, as no pattern emerged, it was dismissed as a myth.

However, French gynaecologists rubbished the research at the “G-Day” conference in Paris, insisting that the famed erogenous zone is far from being a myth.

"The English study is barking up the wrong tree," said eminent French gynaecologist Sylvain Mimoun at the conference.

"It is not a question of genetics but of use," he added.

Another expert, Odile Buisson, claimed at least 56% of women have a G-spot and its effects could be observed in scans, dismissing the English study as “medical machismo”.

The G-spot is named after gynaecologist Ernst Grafenburg, who claimed to have discovered it in 1950.

It has long since been believed that stimulation of the fabled G-spot leads can lead to a vaginal orgasm - the more explosive and elusive sister of the clitoral orgasm.
