The Effect of Letrozole and N-Acetylcysteine on the Expression Levels of Genes Involved in Glucose Metabolism in Patients with Polycystic Ovary Syndrome: A Clinical Trial Study

NAC can improve the quality of oocytes by increasing the expression level of genes involved in the glucose metabolism (PKM2, PFKP) of CCs, thereby potentially improving ART success rate in PCOS patients. Therefore, administering NAC along with letrozole can have a synergistic effect on increasing the expression level of genes associated with blastocyst quality in PCOS patients.
