In modern society, endometrial cancer (EC) and atypical hyperplasia is the most frequent desease which can affect the fertility of young patients. For young patients, there is a growing need to treat tumors and fertility sparing. Advaced studies have confirmed thatfertility preservation therapy has better tumor and pregnancy outcomes in specific patients with early gynecological tumors. Clinically, evidence-based guidelines are urgently needed to guide the screening and treatment of women who are suitable for fertility preservation. Fertility-sparing treatment predominantly involves the use of oral progestins and levonorgestrel-releasing intrauterine devices, which have been shown to be feasible and safe in women with early stage EC and minimal or no myometrial invasion. However, data on the efficacy and safety of conservative management strategies are primarily based on retrospective studies.The present study aims to compared the therapeutic effect of Medroxyprogesterone acetate (MPA) and Levonorgestrel-releasing intrauterine system (LNG-IUS) in early-stage endometrioid carcinoma and atypical hyperplasia patients
