The Gräfenberg Spot, often called the G-Spot, is defined as a bean-shaped area of the vagina. Some women report that it is an erogenous zone which, when stimulated, can lead to strong sexual arousal, powerful orgasms and female ejaculation. The G-Spot is typically described as being located one to three inches (2.5 to 7.6 cm) 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.
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 intercourse. It is also hypothesized that the G-Spot is an extension of the clitoris and that this is the cause of vaginal orgasms.
Sexologists and other researchers are concerned that women may consider themselves to be dysfunctional if they do not experience the G-Spot, and emphasize that it is normal not to experience it. Some women have undergone a plastic surgery procedure called G-Spot amplification (see below) in an effort to enhance its sensitivity.
