G-Spot “Discovery” Doesn’t Please Everyone | Sex Health Headlines

A Florida doctor says he's found the G-spot, a highly sensitive area of the vagina that, when stimulated, brings many women to orgasm. However, some sexual medicine experts reject his claim.

Dr. Adam Ostrzenski, current Medical Director at the Institute of Gynecology in St. Petersburg, published his findings in the April 25, 2012 online edition of The Journal of Sexual Medicine. In his report, he notes that the G-spot is a specific anatomical structure in a woman's front vaginal wall.

Dr. Ostrzenski made this discovery while examining the cadaver of an 83-year-old woman at Warsaw Medical University in Poland. The woman had died 24 hours before the examination.

Dissecting the cadaver's vaginal wall layer-by-layer, he found a sac that contained a bluish structure about a centimeter long that resembled a cluster of grapes. The structure had a head, middle, and tail. The wall of the sac appeared to be erectile tissue.

"This study confirmed the anatomic existence of the G-spot, which may lead to a better understanding and improvement of female sexual function,"; Dr. Ostrzenski said in a press release.

Named for Dr. Ernst Grafenberg, the doctor who first wrote about this area in 1950, the G-spot has been controversial for decades. Some experts don't believe it exists and many women say they are unable to find it.

Dr. Ostrzenski's work has drawn criticism from others in the field.

"It's a single case study involving the dissection of the body of one woman whose sexual experiences are unknown to us," wrote Dr. Debby Herbenick in The Daily Beast. "Did she enjoy vaginal penetration? Did she find G-spot stimulation to be pleasurable or erotic or more or less likely to lead to orgasm? We don't know."

Dr. Herbenick is a research scientist at Indiana University and a sexual-health educator at the Kinsey Institute. She added, "We don't know how many women (if any) have similar structures. And we certainly don't know if the structure has anything to do with G-spot stimulation, sexual pleasure, erotic sensations, or orgasm."

Three sexual medicine specialists, Dr. Barry Komisaruk and Dr. Beverly Whipple (both of Rutgers University) and Dr. Emmanuele Jannini of the University of L'Aquila in Italy, have written a critical commentary that they expect will be published in The Journal of Sexual Medicine.

In an interview with HealthPop, a blog of CBS News, Dr. Komisaruk explained that Dr. Ostrzenski did not clearly identify the type of tissue found. "Without such information, there is no indication of what function it might serve," he said.

Dr. Ostrzenski told HealthPop that his study was designed to look at anatomy, not function. He also told the LA Times that Polish regulations did not allow him to take a tissue sample for closer analysis. However, he planned to return to Poland this spring to conduct further study.
