ORIGINAL RESEARCH-ANATOMY/PHYSIOLOGY: Genetic and Environmental Influences on self-reported G-Spots in Women: A Twin Study

To our knowledge, this is the largest study investigating the prevalence of the G-spot and the first one to explore an underlying genetic basis. A possible explanation for the lack of heritability may be that women differ in their ability to detect their own (true) G-spots. However, we postulate that the reason for the lack of genetic variation-in contrast to other anatomical and physiological traits studied-is that there is no physiological or physical basis for the G-spot.
