Anatomic documentation of the G-spot complex role in the genesis of anterior vaginal wall ballooning

Objectives: To expand previous G-spot anatomical and histological investigations; to examine the G-spot complex anatomic role in the anterior vaginal wall ballooning bio-mechanisms; and to determine, which division of autonomic nervous system (sympathetic or parasympathetic) dominates at the time of female sudden death.

Study design: A prospective-descriptive case series anatomical study on eleven consecutive fresh humane female cadavers was conducted. Anterior vaginal wall stratum-by-stratum macro-dissections were executed in axial, coronal and sagittal plains. Upon G-spot extirpations, micro-dissections were performed. The G-spot tissues were stained with hematoxilin and eosin for histological examinations to authenticate the G-spot anatomical and histological characteristic features.

Results: The G-spot complex was identified and present in all subjects on either the distal vaginal left (more often) or on the right side from the lateral margin of the urethra; the G-spot anatomical and microscopic characteristic features have been authenticated; the G-spot complex expansion elevated anterior vaginal walls in each subject; the autonomic parasympathetic nervous system was the dominant division at the time of female subject sudden death.

Conclusion: This study advances our anatomical and histological understanding of the G-spot complex and its role in the genesis of anterior vaginal ballooning bio-mechanisms. The G-spot complex is under parasympathetic nervous system domination at the time of female sudden death.
