A device and method for male impotence correction and female anorgasmy. An electronic stimulator with at least one pulse generator is implanted inside the body. At least one electrode is installed in the epidural space in the sacrum section of the spinal column and a conductor running under the user's skin electrically connects the electrode to the pulse generator. The stimulator is programmable and may be controlled from outside the body. Upon command initiated by the user or the user's lover the stimulator produces very short low-voltage electrical pulses in the sacrum section that are picked up by the nerves leading to the sex organs of the user, which stimulates arousal in the user's reproductive systems. The pulses are similar to the pulses generated by heart pacemakers. In other preferred embodiments the stimulator includes one or two drug chambers and a tube extending from each chamber to a nerve for producing stimulation of a sex organ. The present invention works on both males and females. In a preferred embodiment, the programmable electronic stimulator is implanted under the skin in the patient's back. Stimulation of the nerves coming out from the parasympathetic part of the spinal cord causes dilatation of the penile arteries in the male and in the clitoris arteries of the female, which results in an erection in the male and pre-orgasmic sensation in the female. In female, the stimulation of the sacral part of the spinal cord increases sexual desire and escalation to the level of orgasm. A preferred embodiment provides for emission stimulation. Emission is stimulated by electrical excitation of the sacral part of the spinal cord by increasing the voltage of the previous impulses. The device may be preprogrammed to set in motion the emission and ejaculation process at a predetermined time interval after the start of the erection process.
