Interest in the sexual function of the female prostate was taken up by Earnst Grafenberg in 1950, who wrote of the "large quantities of a clear, transparent fluid [that] are expelled not from the vulva, but out of the urethra in gushes". -- Grafenberg, Earnst, The Role of the Urethra in Female Orgasm, International Journal of Sexology, Vol III, no 3, p.145-148, February 1950 via http://www.fiawol.demon.co.uk/FAC/femejac.htm [Aug 2004]

The Gräfenberg spot, or G-spot, is a small area in women behind the pubic bone surrounding the urethra and accessible through the anterior wall of the vagina. It is putatively an erogenous zone that when stimulated leads to high levels of sexual arousal and powerful orgasms.

Skene's gland and other approaches

Skene's gland, urethral sponge

Links between G-spot sensitivity and female ejaculation have led to the idea that non-urine female ejaculate might originate from the female paraurethral glands, or Skene's gland: in a study by Tepper et al., tissue from 18 patients was examined and 15 showed prostate-specific antigens. More recent studies have backed up this finding, leading some to call the Skene's glands the female prostate. Consequently, it has been argued that the G-spot is a system of glands and ducts located within the anterior (front) wall of the vagina, about one centimeter from the surface and one third to one-half the way in from the vaginal opening. A similar approach has linked the G-spot with the urethral sponge.

Many researchers have found the connection between the Skene's gland and the G-spot to be weak.

Researchers at the University of L'Aquila have found, using ultrasonography, that women who experience vaginal orgasm are statistically more likely to have thicker tissue in the anterior vaginal wall. In addition, PDE5 activity has been linked to the area of the G-spot and the presence of Skene's glands: in women without Skene's glands, concentrations of PDE5 are much lower.

Researchers state that these findings make it possible for women to have a rapid test to confirm whether or not they have a G spot.
