Increased vaginal blood flow induced by implant electrical stimulation of sacral anterior roots in the conscious woman: a case study.
The sacral anterior nerve roots were stimulated in a conscious female paraplegic by means of an intradural implanted Finetech/Brindley stimulator activated by inductive radio signals. Changes in vaginal blood flow were monitored by a photoplethysmograph. Stimulating S2 and S3 (but not S4) caused significant increases in vaginal pulse amplitude indicating genital vasodilation and increased blood flow.
