Foot orgasm syndrome (FOS)

Reported in a medical journal are details of a Dutch woman who complains of spontaneous orgasm (5 or 6 times per day) triggered by stimulation of her left foot. Seems her symptoms started 18 months after she was in a coma. During intensive care for septic infection it is thought partial nerve regeneration (axonotmesis) may account for the symptoms. Magnetic resonance images (MRI scans) of the woman's brain and her foot showed no abnormalities, although another test revealed some differences between the nerves of her left and right feet. Medical tests confirmed stimulating her left foot with an electric current induced a spontaneous orgasm . Apparently the foot orgasm had different attributes to a standard climax and there were no sexual feelings of desire. The condition has been called Foot Orgasm Syndrome (FOS).

Sensory supply to the pelvic area and feet lie close to each other in the brain and experts believe neural print through may have resulted in the brain misinterpreting the foot stimuli as coming from the naughty bits.

To explore matter further the lady underwent extensive tests including: magnetic resonance imaging (MRI-scan), electromyography (EMG), transcutaneous electrical nerve stimulation (TENS), and blockade of the left S1 dorsal root ganglion. Tests confirmed there was no notable neuro-pathology but TENS stimulation of her left foot elicited an instant orgasmic sensation that radiated from plantar toward the vagina. TENS applied to the left side of the vagina elicited an orgasm that radiated to the left foot. Diagnostic blockade of the left S1 dorsal root ganglion with 0.8 mL bupivacaine 0.25 mg attenuated the frequency and intensity of orgasmic sensation in the left foot with 50% and 80%, respectively. Additional therapeutic blockade of the same ganglion with 0.8 mL bupivacaine 0.50 mg combined with pulsed radiofrequency treatment resulted in a complete disappearance of the foot-induced orgasmic sensations. The woman had no further foot orgasms eight months after the procedure , although she might need to return for another anesthetic injection if her symptoms return.

Now if you have had a similar experience the authors would like to hear from you. Contact Dr Waldinger at:
