We aimed to retrospectively analyze the efficacy and safety of autologous bone marrow mesenchymal stem cells (BM-MSCs) as adjuvant therapy for intrauterine adhesion (IUA) and endometrial repair. All patients had menstrual cramps and significantly increased menstrual flow during three rounds of perfusions with MSC compared to before treatment. However, this effect was reversed and there was no significant difference between the menstrual flow one year after treatment vs before treatment. The IUA scores after three rounds of treatment as well as one and two years after treatments were significantly lower compared to before surgery. No IUA recurrence was observed during the 2-year follow-up. Endometrial thickness had significantly increased during treatment. During the two-year follow-up period, one patient conceived naturally. One patient was successfully implanted after invitro fertilization and embryo transfer. Intrauterine perfusion of autologous BM-MSCs, assisted by adhesiolysis, was effective in preventing postoperative IUA recurrence and partially improved the reproductive prognosis.
