The elusive G-spot, a holy grail of lovers, now has an anatomical location precisely described in the medical literature thanks to a Florida researcher who dissected the cadaver of an 83-year-old woman.
For centuries, women have said they've enjoyed engorgement of the upper, anterior part of the vagina during sexual arousal, but it has never been formally described in medical literature.
In the May issue of the Journal of Sexual Medicine, Dr. Adam Ostrzenski of the Institute of Gynecology in St. Petersburg, Fla., describes where he found the G-spot while dissecting the 83-year-old cadaver in Poland.
'This case study in a single cadaver adds to the growing body of literature regarding women's sexual anatomy and physiology.' — Irwin Goldstein, editor in chief of Journal of Sexual Medicine
"The anatomic existence of the G-spot was documented with potential impact on the practice and clinical research in the field of female sexual function," Ostrzenski concluded.
The dissection revealed the G-spot was on the dorsal or back perineal membrane, 16.5 millimetres from the upper part of the urethra, creating a 35-degree angle with the lateral or side border of the structure.
When the spot, which he described as "bluish grapeline compositions," was removed from a sac, it extended to 33 millimetres — suggesting it was designed to contract and expand, he said.
"The anatomic discovery of the G-spot existence may inspire a new study for establishing the anatomic presence of 'a female prostate.'"
Ostrzenski also backed calls to revise traditional approaches in textbooks to female organ anatomy coupled with new terminologies.
The G-spot in the cadaver was under five layers of connective tissue and muscle in an area that is not normally accessed during gynecological surgery. Ostrzenski acknowledged he examined only one cadaver soon after death and he was unable to take tissue samples for confirmation.
"This case study in a single cadaver adds to the growing body of literature regarding women's sexual anatomy and physiology," the journal's editor in chief, Irwin Goldstein, said in a release.
The spot was named after German gynecologist Ernst Grafenberg, who wrote a paper titled "The role of the urethra in female orgasm" in 1950.
The anatomical source of female orgasm has been debated over the centuries, with some pointing to the vaginal walls and others to the clitoris.
Sex therapists often stress the psychological aspects of female orgasm.
