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.
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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| MenSCs group | Experimental | Study group, treated with autologous intra-ovarian MenSCs injection and monitored for spontaneous pregnancy for 3 months after intervention. ICSI was used in cases where the pregnancy did not occur naturally. |
|
| ICSI group | No Intervention | Control group, monitored for spontaneous pregnancy for 3 months after their last ovarian stimulation for ICSI or IVF. ICSI was used in cases where the pregnancy did not occur naturally. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Autologous Menstrual Blood Stem Cells | Biological | The menstrual blood of patients in the MenSCs treatment group was collected in sterile menstrual cups on the second day of menstruation, and directly transferred to a class B clean room for MSC isolation and culture. All cell quality control studies were performed prior to the International Conference of Harmonization Q2 (ICH Q2) guidelines. The density of the final product was 20×106 cells/ml. 150 μl of the prepared suspension was injected intravaginally into each ovary of the patient under general anaesthesia |
| Measure | Description | Time Frame |
|---|---|---|
| Spontaneous pregnancy rate | Number of participants that establish a spontaneous clinical pregnancy after stem cell injection | 3 months after stem cell injection |
| Pregnancy rate after ICSI | Number of participants that establish a clinical pregnancy after embryo transfer | 4 weeks after embryo transfer |
| Measure | Description | Time Frame |
|---|---|---|
| Hormone levels | Change from baseline in Anti-Müllerian hormone (AMH), serum follicle stimulating hormone (FSH), and antral follicle count (AFC) | 2 and 4 months after stem cell injection |
| Number of oocytes |
