The debate has raged for some time as to whether or not the fabled G-spot exists.

But one scientist has concluded that the much-talked-about area believed to be the point of origin for the female "vaginal" orgasm does exist but only in some women, according to a small study published in the Journal of Sexual Medicine.

Emmanuele Jannini of the University of L'Aquila in Italy used an ultrasound to scan the area of the vagina where the G-spot, also called the Gräfenberg spot after Ernest Gräfenberg, the man who discovered it, is located.

Jannini determined that the tissue on the front vaginal wall located behind the urethra was noticeably thicker in the women who reported having vaginal orgasms. The thicker tissue, the study concluded, demonstrates the presence of a G-spot.

"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," French news agency AFP quoted Jannini as saying. "Women without any visible evidence of a G-spot cannot have a vaginal orgasm.''
