The G‐spot: an observational MRI pilot study

Abstract

Objectives To identify a G-spot complex (GSC) in vivo in MRI examinations at 1.5 Tesla field strength.Design Observational study.Setting Single centre.Population Twenty-one consecutive patients (January-March 2014).Methods Imaging analysis of routine imaging protocols for usual medical indications with and without concomitant opacification of the vaginal cavity with inert ultrasound gel. The gel distends the otherwise collapsed vaginal walls, allowing for an improved discrimination of anatomic features. The macroscopic and histological results recently derived from the dissections of fresh cadavers by Ostrzenski et al. were translated into imaging characteristics to be expected in the respective MRI sequences (e.g. T1-and T2-weighted) in search of an in vivo correlate of the GSC. Age, menopause status, medical indication and diagnosis were co-variables.Main outcome measures To analyse primarily whether MRI imaging is able to depict a distinct morphological entity in vivo matching the GSC, based on anatomical descriptions published recently. The elaboration of an appropriate MRI-imaging protocol was a secondary aim.Results A total of 21 studies were obtained. A GSC was identified within the anterior vaginal wall in 13/21 patients (62%). In all, 10/ 21 (48%) had vaginal gel opacification. We identified a GSC in 10/ 10 patients (100%) with opacification in all three planes of the T2 images. This was only true for 3/11 cases (27%) without opacification.Conclusions There is evidence for an in vivo morphological correlate to the postmortem anatomical findings of a GSC described by Ostrzenski et al.; its visibility in MRI imaging can be significantly improved with vaginal opacification by ultrasound gel.

G‐Spot Anatomy and its Clinical Significance: A Systematic Review

“…The same group overlooked data in the existing literature such as the histological description of a nerve ganglion, which was considered the histological landmark distinguishing the G‐spot from the vaginal and urethral walls (Ostrzenski et al, ). Additionally, they omitted information from the in vivo MRI study that revealed the G‐spot anatomical structure in 100% of cases when vaginal contrast was used (Maratos et al, ).…”

“…The structural existence of the G‐spot was verified by postmortem anatomical studies, MRI investigation in vivo, and G‐spot histology (Ostrzenski et al, ; Ostrzenski, ; Maratos et al, ). Thabet () conducted an intraoperative anatomical study, and Hoag et al () performed a postmortem investigation.…”

Re: The G‐spot: an observational MRI pilot study

“…stated ‘According to the description of Ostrzenski et al. The G‐spot was a neurovascular complex embedded within a fibroadipose tissue bed, in the anterior vaginal wall… To identify a G‐spot complex (GSC) in vivo in MRI examinations… MRI imaging data on the presumed anatomical location of the G‐spot is currently insufficient at best.’…”

“…The G‐spot is an erotically sensitive spot, its stimulation causes intense orgasms, therefore it is incomprehensible to study women, in vivo, without their sexual history and with no evidence of the so‐called ‘G‐spot’ orgasms, the conclusions of Maratos et al. concerning the ‘identification of G‐spot by MRI in 13/21 patients,’ have no scientific basis.…”

“…Maratos et al . stated ‘MRI helped to demonstrate that the distal vagina and urethra are clearly related, forming a midline core to the clitoris… the concept of the clitourethrovaginal complex.’…”
