SUMMARY :
63 genitally active female patients have been interviewed during gynaecological
consultations, about the presence and forms of their orgasms.
Hence, the contractions of the muscles of the perineum during orgasm has been
named "Vaginal Orgasmic Motor Responses" (VOMR).
A clinical study of the perineal musculature of the patients was carried out.
Whether they experience VOMR or not, all the patients know their perineal musculature
in the same proportion. But most of all, the lower the VOMR’s, the higher
the percentage of patients with a known and functional perineal musculature.
This result leads us to ponder on the respective role of the levator ani muscles
(innervated by the S3 and S4 roots of the pudental plexus), and of the obturator
internus muscle (innervated by the internal obturator nerve coming from the
lumbosacral bundle and from the first sacral root of the sacral plexus).
