Conclusion
impaired uterine hemodynamics, endometrial cell therapies
Overall, the study demonstrates the potential of the autologous PRP and autologous minimally manipulated endometrial cell therapies for impaired uterine hemodynamics and chronic endometrial insufficiency, as indicated by higher rates of Doppler visualization of the uterine spiral arteries and, above all, the enhanced endometrial receptivity with improved outcomes in ART programs for patients with a history of implantation failure.
