How is the G-spot like the Loch Ness Monster? A lot of people believe it exists, but there’s precious little scientific evidence to prove it.

Women and men alike have placed stock in the notion that a certain area within the vagina is so extra-sensitive that its stimulation can lead a woman’s experiencing orgasm.

Alas, the latest research reveals that decades of scientific research have yet to confirm that there’s any such thing as a G-spot or to reveal exactly how such a spot might work to enhance women’s sexual satisfaction.

Reporting earlier this month in the Journal of Sexual Medicine, researchers from the Yale-New Haven Hospital and the Rambam Healthcare Campus in Haifa, Israel reviewed all the legitimate scientific literature about the G-spot -- named for the German gynecologist Ernst Gräfenberg, who in 1950 first described a pleasure spot on the anterior wall of the vagina -- produced between 1950 and 2011.

They found that anecdotal evidence supporting the G-spot’s existence abounds; the majority of women believe G-spots exist, the study notes, and most previous research is based largely on such anecdotal findings. But scientific support is scant. It’s not clear that the area known as the G-spot (“a 1-2 cm area on the front wall of the vagina close to the bladder and urethra, about halfway between the pelvic bone and the cervix, which in some women was especially sensitive to direct mechanical stimulation,” as the study defines Gräfenberg’s discovery) is any more sensitive than other parts of the vagina; nor is it clear that stimulating any part of the female body other than the clitoris leads to orgasm.

The authors acknowledge that perhaps the right kind of research to pin down the G-spot’s existence just hasn’t yet been done.

Of course, just because scientists haven’t yet definitively determined that the G-spot is a real phenomenon doesn’t mean laypeople can’t keep searching, adding their own incremental, anecdotal findings to the body of knowledge.

Or, as the authors of the paper put it, “Whether the G-spot actually exists is probably less interesting than the search and desire for its existence.” Do you believe in the G-spot?
