Through careful dissection of an 83-year old cadaver in Poland, Ostrzenski uncovered a blue grape-like sack deep beneath five layers of vaginal tissue in the same area where women report feeling G-spot pleasure. It was about 8 millimeters (0.3 inches) long and about half as wide.
The rope-like, highly stretchable structure lay just beneath a layer of strong fascia, and appeared to be made of erectile tissue, Ostrzenski reports today in The Journal of Sexual Medicine. He believes that previously, surgeons haven't dug deeply enough to find it.
With sexual arousal, Ostrzenski suspects, surrounding tissues open up like a fist to allow the sack to emerge in some women, offering the opportunity for pleasure if stimulated in the right way. Fascia that is too relaxed or otherwise damaged from childbirth or other events could prevent the G-spot from emerging in many women.
If verified, the discovery has an endless number of possible applications, Ostrzenski said. A procedure that his website refers to as G-spotplasty, for example, could restore function in women whose fascia in the region is too loose. He is also working on a device that would more effectively target the spot.
