- The G-spot is named after German gynecologist Ernst Grafenberg, who theorized a female erogenous zone on the anterior wall of the vagina in a paper published in 1950. The term was coined in Addiego, et al in the 1981 publication of "Female Ejaculation: A Case Study" in the Journal of Sex Research 17 (1): 13-21.
- The G-spot is supposedly located anywhere from 1 to 3 inches on the anterior wall of the female vagina, directly behind the pubis bone.
- Most evidence for the G-spot's existence is based on anecdotal observations and investigative methods conducted with only small samples of participants, as noted in "The G-Spot: A Modern Gynecologic Myth." Examinations of the area purported to be the location of the G-spot have proven inconclusive, as the area has not shown to contain a higher density of nerve endings than anywhere else in the vagina. There are theories that the G-spot is homologous to the urethral sponge, as it is located near the Skene's Glands, an area of the vagina known to cause female ejaculation. Associations with G-spot stimulation and female ejaculation have led some to hypothesize that the two are in some way connected--if not the same thing--though this is tenuous at best.
- The most famous supporters of the existence of the G-spot include the first to publish extensively on the subject--Alice Kahn Ladas, Beverly Whipple and John D. Perry in "The G Spot and Other Discoveries About Human Sexuality." The book has since been published in many languages and popularized the term "G-spot." Another supporter is Dr. Malcolm Freeman, a sex therapist and professor of gynecology at Emory University. In a Time magazine article written in 1982, he is quoted as saying "It's very clear that the spot exists. Some women have a small tissue buildup, a remnant of prostate vestige." Detractors of the existence of the G-spot are many. They include Dr. J. Jones Stewart, a Pasadena-based gynecologist, and Dr. Kermit Krantz, chairman of obstetrics and gynecology at the University of Kansas Medical Center in Kansas City. He believes the so-called G-spot has been known of for centuries and that simply giving it a name does little to prove its existence. Krantz says the lack of any anatomical basis is enough to disprove its existence.
- According to a study conducted in 2008 at the University of L'Aquila in Italy, ultrasounds revealed that women who claimed to experience vaginal orgasms possessed a region of thicker tissue in the area where the G-spot is said to exist. Those lacking this thickening of tissue claimed they have never experienced a vaginal orgasm.
