A search that has preoccupied many women for years – not to mention their partners – may finally be over. An Italian scientist believes he may have found the female G-spot.

Emmanuele Jannini, of the University of L’Aquila, claims to have found the first anatomical evidence for the existence of the elusive and controversial pleasure point, which some women say triggers powerful vaginal orgasms. His research could also explain why so many women have searched for their G-spot in vain: it suggests that not all of them have one.

The G-spot is named after Ernst Gräfenberg, a German gynaecologist who in 1950 proposed that a sensitive point on the vaginal wall could provoke particulary intense orgasms in some women, which differ from normal orgasms caused by clitoral stimulation. Finding it has since become a staple of good-sex handbooks.

Its existence, however, has been widely questioned. Many women have always found it impossible to locate, leading them to doubt their own sexual skills or that of their partners, or to wonder whether the whole idea of a vaginal pleasure point is a myth.

Dr Jannini has found anatomical differences between women who can have vaginal orgasms and those who cannot and told New Scientist magazine that it may be possible to develop an ultrasound test that can tell women whether they have one.

He used ultrasound to examine nine women who said that they could have vaginal orgasms and eleven who said that they could not. He found that the tissue between the vagina and urethra was thicker in the first group, which could be linked to their ability to have an orgasm.
