Abstract

Methods of treating premature ejaculation include arranging one or more electrodes to face dorsal penile nerves (DPNs) of a patient with premature ejaculation, and applying an electro stimulation having a frequency and a current by which seminal fluid expulsion is not induced in the patient by the one or more electrodes during a time period from before the start of sexual intercourse to ejaculation. The electro stimulation reversibly extends an intravaginal ejaculatory latency time (IELT) of the patient. Methods of controlling a premature ejaculation treatment device are also provided.

Claims

1. A method of treating premature ejaculation, comprising:

arranging one or more electrodes to face dorsal penile nerves (DPNs) of a patient with premature ejaculation; and

applying an electro stimulation having a frequency and a current by which seminal fluid expulsion is not immediately induced in the patient by the one or more electrodes during a time period from before the start of sexual intercourse to ejaculation;

wherein;

applying the electro stimulation comprises applying the electro stimulation for a period of time that does not exceed 60 minutes per day; and

the electro stimulation reversibly extends an intravaginal ejaculatory latency time (IELT) of the patient.

2. The method according to claim 1, wherein the frequency of the electro stimulation is 100-5,000 Hz.

3. The method according to claim 1, wherein arranging one or more electrodes comprises implanting one or more electrodes surgically under skin at a proximal portion of the penis of the patient in contact with DPNs.

4. The method according to claim 1, wherein arranging one or more electrodes comprises arranging one or more electrodes to face less than all DPNs of the patient.
