Results: After treatment with letrozole and metformin, 77.4% of patients showed significant response to therapy in the form of inactive and atrophic endometrium (P value < 0.001). The clinical response to treatment was observed in 18 (58.1%) women as complete relief of bleeding or decreased hemorrhage in 6 (19.4%) women.
