OBJECTIVE: To investigate the potential mechanism of electroacupuncture (EA) in alleviating premature ovarian insufficiency (POI) and to provide a theoretical basis for EA treatment of POI. METHODS: For this purpose, a POI mice model was developed by injecting 12 mg/kg busulfan and 120 mg/kg cyclophosphamide intraperitoneally to induce POI. It was then proceeded by EA intervention at Guanyuan (CV4) acupoint on the second day following modeling. Similarly, apoptosis in ovarian granulosa cells was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling staining, while enzyme-linked immunosorbent assay was employed for measuring serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E RESULTS: Analysis of serum levels of various hormones indicated that serum FSH and LH were reduced in EA compared to the POI group, while E CONCLUSIONS: EA at the Guanyuan (CV4) acupoint protected the granulosa cell by inhibiting cell apoptosis and promoting mitophagy, which was mediated by the Hippo-YAP/TAZ pathway.
