This Abstract describes a method to restore and/or improve the libido, the sex drive, in males and females, without introducing any external unnatural drugs. The process utilizes a TENS/EMS (Transcutaneous Electrical Nerve Stimulation/Electronic Muscle Stimulation) machine to naturally generate the increased production by the human body's nerve fiber's neurotransmitters. Neurotransmitters that help the Libido include Serotonin, beta-Endorphin, Cortisol, Adrenocorticotropic hormone (ACTH), gamma-Aminobutyric acid (GABA), and Dehydroepiandrosterone (DHEA). This leads to the production of higher levels of estrogen, testosterone, or progesterone. The method requires a TENS/EMS power source, two electrodes, wiring, and optionally two additional electrodes. TENS/EMS units have no side effects other than possible skin irritation (where the electrodes are placed on the skin； if the machine is left on too long). Using a TENS/EMS unit for three-to-four times a day, for 20 minutes per session, can help restore and/or strengthen the Libido. Over the course of less than two years it is possible to restore the libido. From a nonexistent sex drive, men and women can restore their ability to reach a culmination again, without drugs.
