The mysterious G spot - supposedly a route to female sexual satisfaction - can be located with ultrasound, claim Italian scientists.
Some women say stimulating a certain part of the vagina triggers powerful orgasms, but medicine has not been able to pin down the exact location.

Researchers told New Scientist magazine they found an area of thicker tissue among the women reporting orgasms.

But specialists warned there could be other reasons for this difference.

The existence of the G spot has remained controversial since the 1980s, when the term was coined as a way to explain why some women were able to achieve orgasm through vaginal stimulation, while others were not.

Some specialists claim that the term has led to over-anxiety among women who cannot reach satisfaction this way, and their partners.

The latest research, published in the Journal of Sexual Medicine, was carried out the Dr Emmanuele Jannini at the University of L'Aquila, and involved just 20 women.

Ultrasound was used to measure the size and shape of the tissue beyond the "front" wall of the vagina, often suggested as the location of the G spot.

In the nine women who reported being able to achieve vaginal orgasm, the tissues between the vagina and the urethra - which carries urine out of the body - were on average thicker than in the 11 women who could not reach orgasm this way.
