Cell therapy of poor ovarian responders using MenSCs Improvement of pregnancy rate and live birth rate in poor ovarian responders by intraovarian administration of autologous menstrual blood stem cells

چکیده مقاله

Background Despite numerous studies been accomplished to examine the effects of different stimulation protocols in infertility treatment of poor ovarian responders PORs , there is no certain recommendation for clinical handling of these women which often leads to oocyte/embryo donation Objective: In this study, effect of stem cell therapy using autologous menstrual blood mesenchymal stem cells MenSCs in fertility potential of PORs has been examined Study design:36 POR women based on Bologna criteria undergoing conventional IVF embryo transfer were included in this study The eligible women were divided into main stem cell therapy and control routine ICSI plan groups The cultured MenSCs were injected into left ovary of stem cell group while control group underwent routine ICSI plan Changes in AMH, antral follicles count AFC , oocytes and embryos number, clinical pregnancy rate and live birth rate were followed in both groups up to one year after treatment Results: Cell therapy using MenSCs was completely safe 26 7% of participants in stem cell group got naturally pregnant during 3 months after cell administration, in contrast to no natural conception in control group P=0 04 The mean AMH level did not significantly differ with that of previous cycle or control group Although mean AFC and oocytes number in stem cell group did not indicate considerable difference with those of control group, raise of these parameters in comparison with previous cycle was significant both P=0 01 Moreover, oocyte fertilization rate in stem cell group was remarkably higher than pre treatment 92% vs 76%, P=0 01 Totally, 46 7% of women in main group had clinical pregnancy which was higher than control group 12 5%, P=0 04 Meanwhile, 33 3% of pregnancies ended with live birth in stem cell group that was considerably greater than control group 33 3% vs 6 3%, P=0 05 Conclusion: This study shows safety and efficacy of cell therapy using MenSCs to restore fertility capability of POR women Therefore, considering easy access to sampling and isolation along with high propagation potential of these stem cells as autologous source, it seems that this therapeutic approach would have crucial effectiveness in POR women that tackle with infertility and inevitably should be referred to egg donation
