Phase 3
Completed
Conditions
Poor Ovarian Response
Infertility, Female
Interventions
Biological: Autologous Menstrual Blood Stem Cells
Registration Number
NCT05703308
Lead Sponsor
Avicenna Research Institute
Brief Summary

In this controlled trial, poor ovarian responder women will be treated with transplantation of autologous menstrual blood stem cells. The investigators will attempt to assess the safety and efficacy of this procedure for the treatment of infertility in POR patients compared to control group.

Detailed Description

With economic development, procreation delays have resulted in more women seeking medical help for infertility treatment. Because the quality and quantity of oocytes are affected by physiological age, despite advances in assisted reproductive technology (ART), managing infertility in women with poor ovarian response (POR) remains a daily challenge for physicians.

Adult mesenchymal stromal cell (MSC) therapy has gained particular interest in recent years because it may provide a supportive microenvironment for oocyte development from quiescent primordial follicles. Human MSC transplantation has been shown in preclinical studies to host ovaries and restore their function and structure premature ovarian failure (POF) animal models.

Because of their encouraging characteristics such as ease of access, high availability, monthly repeatability of sampling, less ethical considerations, lack of tumor-causing potential, protected property, and significant trans-differentiation capacity, endometrial-derived stromal cells have been considered in a wide range of studies since 2007. Menstrual blood-derived stromal cells (MenSCs), on the other hand, are derived from endometrial tissue and can be collected in a non-invasive manner, making them especially useful in the treatment of reproductive disorders. The investigators attempted to assess the safety and efficacy of intraovarian injection of MenSCs for the treatment of infertility in POR patients based on this evidence.

The results of this clinical trial's phases I and II indicated that Men-MSCs could be considered as a potential treatment to restore the fertility capability of POR women. Based on these findings, the investigators have designed a Phase III controlled trial of autologous MenSC therapy for patients with POR.
