The Grafenberg spot, better known as the G-spot, is an area within the anterior (or front) wall of the vagina, about 1 centimeter from the skin’s surface and one third to one half the distance from the vaginal opening to the back of the vagina. It consists of a system of glands (Skene’s glands) and ducts that surround the urethra. This area is believed to be the female counterpart to the male prostate gland, developed from the same embryonic tissue.
The G-spot has generated considerable interest because of reports that some women experience sexual arousal, orgasm, and an ejaculation of fluid when stimulated there (Darling et al., 1990), although many women do not have such an area of increased sensation. We will discuss the role of the G-spot in female sexual response more fully in Chapter 6.
