5. The method of claim 1 , wherein the acupoint comprises at least one of acupoints BL52, BL23, and GV4.
6. The method of claim 1 , wherein the T 3 value is at least 10 minutes and less than 60 minutes, and wherein the T 4 value is at least 1440 minutes.
7. The method of claim 1 , further comprising:
receiving, by the electroacupuncture device from a device external to the electroacupuncture device, a control command that sets the T 3 value and the T 4 value to appropriate values configured to treat the erectile dysfunction condition;
wherein the generating of the stimulation sessions is performed in accordance with the control command.
8. The method of claim 7 , wherein the receiving of the control command comprises detecting, with an electromagnetic field sensor included in the electroacupuncture device, a magnetic field generated by the device external to the electroacupuncture device.
9. The method of claim 1 , wherein the annular electrode is located on the first surface of the housing.
10. The method of claim 1 , wherein the annular electrode comprises a ring electrode located around a perimeter edge of the housing.
11. The method of claim 1 , wherein:
the electrode array further comprises a plurality of electrodes located on a lead that is attached to the electroacupuncture device; and
the applying of the stimulation sessions to the target tissue location by way of the electrode array further comprises applying the stimulation sessions to the target tissue location by way of the plurality of electrodes located on the lead.
