Resveratrol is a natural plant antitoxin widely found in grapes, mulberries, and other plants. Resveratrol mediates a variety of pharmacological effects, including antioxidant, immunomodulatory, anti-inflammatory, and anti-apoptotic, and plays a protective and therapeutic role in the development of several ROS-related diseases, including POI/POF.

The preliminary experiments of the investigators' group examined the gene expression in ovarian granulosa cells of POI patients and normal controls using high-throughput sequencing technology. The investigators found that the expression of NOX complex NCF1, NCF2, NCF4 and CYBB subunit genes were upregulated in ovarian granulosa cells of POI patients compared with normal controls, suggesting that the development of POI may be related to the NOX complex subunit gene and The development of POI may be related to the abnormal expression of genes and proteins of NOX complex subunits. Based on the results of previous experiments and available literature reports, investigators compared ovarian function, embryonic laboratory indices, pregnancy outcome and cellular level NOX/ROS/oxidative stress changes of POI patients in the RES-treated and non-RES-treated groups by collecting blood and ovarian granulosa cell samples to analyze the effects, mechanisms of action and specific RES application in antioxidant therapy for POI NOX subunit targets to provide a reliable scientific basis for the clinical treatment of POI by RES.
