London, Feb 21 : After years of bedroom exploration and debate, a row about the location of the fabled G spot- the route to female sexual satisfaction - might be finally over, for an Italian scientist believes that he has found it.

The G spot, named after a German gynecologist called Ernst Graefenberg who first proposed its existence in 1950, is said to be a highly sensitive area in the vagina that, when stimulated, gives a woman a powerful orgasm.

However, its location has been clouded by evidence that is subjective or downright contradictory, and some experts have even concluded that it does not exist.

But according to Italian researcher Emmanuele Jannini, the G spot does exist, but only among those women who are lucky enough to possess it.

Ultrasound scans revealed clear anatomical differences between women who said they experienced vaginal orgasms and a group of women who did not. The scans identified a region of thicker tissue where the G spot was rumored to be lurking, which was not visible in the women who had never had a vaginal orgasm.

Doctors at the University of L'Aquila in Italy, where the study was conducted, said that the findings make it possible for women to have a rapid test to confirm whether or not they have a G spot.

"A simple test could tell you if it is time to give up the hunt for your G spot or if your partner just needs to try harder. For the first time it is possible to determine by a simple, rapid and inexpensive method if a woman has a G spot or not," New Scientist quoted Jannini at the University of L'Aquila in Italy, as saying.

The G spot is only thought to affect a woman's ability to have vaginal orgasms, so if women do not have one "they can still have a normal orgasm through stimulation of the clitoris," Jannini said.

In the study, the team used ultrasound to scan nine women who had experienced vaginal orgasms and 11 women who said they had not. In the first group of women, the tissue between the vagina and the urethra was found to be substantially thicker than in the other women.

Jannini, whose study appears in the Journal of Sexual Medicine, said the scans suggested that "women without any visible evidence of a G spot cannot have a vaginal orgasm".

Jannini accepts that there are limitations to his study. In particular, the small number of women he studied doesn't allow him to say what proportion of all women have G spot - although it would seem that a large number do not.
