Viewers ask their craziest science questions, then it's up to Gus Sorola and Chris Demarais to match wits with evolutionary biologist Sally Le Page in search of an answer. No science theory is too dumb, but someone on this panel probably is. (It's Chris.)

The G-spot, also called the Gräfenberg spot (for German gynecologist Ernst Gräfenberg), is characterized as an erogenous area of the vagina that, when stimulated, may lead to strong sexual arousal, powerful orgasms and potential female ejaculation. It is typically reported to be located 5–8 cm (2–3 in) up the front (anterior) vaginal wall between the vaginal opening and the urethra and is a sensitive area that may be part of the female prostate. The existence of the G-spot has not been proven, nor has the source of female ejaculation. Although the G-spot has been studied since the 1940s, disagreement persists over its existence as a distinct structure, definition and location. A 2009 British study concluded that its existence is unproven and subjective, based on questionnaires and personal experience. Other studies, using ultrasound, have found physiological evidence of the G-spot in women who report having orgasms during vaginal intercourse. It is also hypothesized that the G-spot is an extension of the clitoris and that this is the cause of orgasms experienced vaginally. Sexologists and other researchers are concerned that women may consider themselves to be dysfunctional if they do not experience G-spot stimulation, and emphasize that this is not abnormal.

The release of fluids had been seen by medical practitioners as beneficial to health. Within this context, various methods were used over the centuries to release “female seed” (via vaginal lubrication or female ejaculation) as a treatment for suffocation ex semine retento (suffocation of the womb), female hysteria or green sickness. Methods included a midwife rubbing the walls of the vagina or insertion of the penis or penis-shaped objects into the vagina. In the book History of V, Catherine Blackledge lists old terms for what she believes refer to the female prostate (the Skene's gland), including the little stream, the black pearl and palace of yin in China, the skin of the earthworm in Japan, and saspanda nadi in the India sex manual Ananga Ranga. The 17th-century Dutch physician Regnier de Graaf described female ejaculation and referred to an erogenous zone in the vagina that he linked as homologous with the male prostate; this zone was later reported by the German gynecologist Ernst Gräfenberg. Coinage of the term G-spot has been credited to Addiego et al. in 1981, named after Gräfenberg, and to Alice Kahn Ladas and Beverly Whipple et al. in 1982. Gräfenberg's 1940s research, however, was dedicated to urethral stimulation; Gräfenberg stated, “An erotic zone always could be demonstrated on the anterior wall of the vagina along the course of the urethra”. The concept of the G-spot entered popular culture with the 1982 publication of The G Spot and Other Recent Discoveries About Human Sexuality by Ladas, Whipple and Perry, but it was criticized immediately by gynecologists: some of them denied its existence as the absence of arousal made it less likely to observe, and autopsy studies did not report it.
