Electroacupuncture for Diminished Ovarian Reserve

For BL33, insert the needle to the third posterior sacral foramina to a depth of 80-100mm. For ST25, EX-CA1 and RN4, the needle will be inserted vertically and quickly through the skin, and then slowly and vertically penetrate through the layer of fatty tissue, up into the muscles of the abdominal wall (until the moment of resistance is sensed on the tip of the needle and the participant feels a sting). The electric stimulator will be put on the BL33 and EX-CA1 with a continuous wave, 20 Hz, 1.0-4.0 mA.

HRT, dehydroepiandrosterone (DHEA) and herb decoction could be used for this group. Time frame of treatment is not fixed. Herb decoction will be given to participants based on the principle of syndrome differentiation (a diagnosing method in Traditional Chinese Medicine).
