The “G-Spot” Is Not a Structure Evident on Macroscopic Anatomic Dissection of the Vaginal Wall

摘要

Abstract Background Controversy exists in the literature regarding the presence or absence of an anatomic “G-spot.” However, few studies have examined the detailed topographic or histologic anatomy of the putative G-spot location. Aim To determine the anatomy of the anterior vaginal wall and present detailed, systematic, accessible findings from female cadaveric dissections to provide anatomic clarity with respect to this location. Methods Systematic anatomic dissections were performed on 13 female cadavers (32–97 years old, 8 fixed and 5 fresh) to characterize the gross anatomy of the anterior vaginal wall. Digital photography was used to document dissections. Dissection preserved the anterior vaginal wall, urethra, and clitoris. In 9 cadavers, the vaginal epithelial layer was reflected to expose the underlying urethral wall and associated tissues. In 4 cadavers, the vaginal wall was left intact before preservation. Once photographed, 8 specimens were transversely sectioned for macroscopic inspection and histologic examination. Outcomes The presence or absence of a macroscopic anatomic structure at detailed cadaveric pelvis dissection that corresponds to the previously described G-spot and gross anatomic description of the anterior vaginal wall. Results Deep to the lining epithelium of the anterior vaginal wall is the urethra. There is no macroscopic structure other than the urethra and vaginal wall lining in the location of the putative G-spot. Specifically, there is no apparent erectile or “spongy” tissue in the anterior vaginal wall, except where the urethra abuts the clitoris distally. Clinical Implications The absence of an anatomic structure corresponding to the putative G-spot helps clarify the controversy on this subject. Strengths and Limitations Limitations to this study include limited access to specimens immediately after death and potential for observational bias. In addition, age, medical history, and cause of death are not publishable for privacy reasons. However, it is one of the most thorough and complete anatomic evaluations documenting the anatomic detail of the anterior vaginal wall. Conclusion The G-spot, in its current description, is not identified as a discrete anatomic entity at macroscopic dissection of the urethra or vaginal wall. Further insights could be provided by histologic study. Hoag N, Keast JR, O'Connell HE. The “G-Spot” Is Not a Structure Evident on Macroscopic Anatomic Dissection of the Vaginal Wall.
