Abstract
The circumvaginal musculature had been of interest to sex researchers and therapists dating back at least as far as Dickinson and Van de Velde. Until recently, much of the information in this area was anecdotal and theoretical. Recent advances in instrumentation and neurophysiology are beginning to make advances in a scientific understanding of this area. This paper presents a review of past and present work in this area and uses this information to make some theoretical speculations.
