Not Applicable

Recruiting

• Conditions: Infertility and Miscarriage

• Registration Number: NCT07039097
• Lead Sponsor: The Third Xiangya Hospital of Central South University

Brief Summary

The study aims to compare the effects of transcervical resection of septa (TCRS) and expectant management on the natural pregnancy outcomes of patients with septate uterus without recurrent abortion, also covering the treatment of other infertility factors in infertile patients who aim at natural conception. The research attempts to answer whether TCRS can improve the live birth rate, pregnancy rate and pregnancy outcomes for septate uterus patients planning natural pregnancy, so as to provide evidence-based medical evidence for the selection of clinical treatment methods for such patients.
