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 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 in an effort to enhance its sensitivity
