Clinical Efficacy and Pregnancy Outcomes of Doxycycline Combined With Medroxyprogesterone Acetate Therapy for Chronic Endometritis(CE) in Patients With Recurrent Reproductive Failure(RRF): A Prospective Randomized Controlled Trial
A Prospective Randomized Controlled Trial, the goal of this clinical trial is to evaluate the efficacy and safety of doxycycline alone versus doxycycline plus medroxyprogesterone acetate (MPA) in women with chronic endometritis (CE), and to assess subsequent reproductive outcomes.

Participants will be followed for reproductive outcomes, including pregnancy , ongoing pregnancy, spontaneous miscarriage, and live birth.
• women aged 20-45 years;
• plans to conceive within 12 months;
• chronic endometritis(CE) confirmed by endometrial CD138 immunohistochemistry (IHC);
• a diagnosis of recurrent reproductive failure(RRF);
• willingness to undergo hysteroscopy and endometrial biopsy;
