It has proved frustratingly elusive for more than 70 years, but scientists say they have finally worked out why men can’t find the ‘G-spot’, it isn’t there.

Doctors say there’s no proof women have a small, super-sensitive region that could create particularly powerful orgasms when aroused.

The erogenous zone was named after German gynaecologist Ernst Gräfenberg, who first suggested the existence of a dense network of nerve endings in the 1950s. But a new study of 17 middle-aged women has found no evidence of such a spot, but ‘a fairly even distribution’ of nerves instead.

Writing in the International Urogynaecology Journal, a team of medics from Istanbul said the ‘anatomical evidence for the presence of the G spot’ was ‘scant, insufficient and weak’.

Although Dr Gräfenberg who also invented the IUD coil contraceptive suggested the existence of the zone, he was too modest to name it after himself.

The expression was coined by American sexologists in the 1980s and quickly gained popularity as well as spawning a new way of marketing sex toys and treatments.

Even though it had been discussed for decades, the first evidence for the existence of the G-spot came just eight years ago, following the examination of a single 83-year-old woman. The man who published that discovery subsequently invented a procedure dubbed a ‘G-spotplasty’ intended to increase sexual satisfaction, despite scepticism from some colleagues.

Although G-spot therapies have become a multi-million dollar business, Devan Stahl, from Michigan State University, has said there is ‘virtually no evidence that these therapies work outside a placebo effect’.

And those who believe the G-spot is a myth say the notion makes women feel needlessly insecure. A survey for Cosmopolitan magazine found half of women feel inadequate or frustrated feeling others can orgasm in a way they can’t.

It also found that 22 per cent of men said finding the woman’s G-spot is the number one goal of sex.

Since the 2012 report, several other studies have failed to produce conclusive evidence a single G-spot exists.
