ClinConnect Summary

This clinical trial is exploring a new treatment for women who have a thin endometrial lining, which can affect fertility. The study is specifically looking at whether specially engineered stem cell exosomes, derived from umbilical cords, can help increase the thickness of the endometrium compared to traditional stem cell exosomes and a common treatment called platelet-rich plasma (PRP). By injecting these treatments directly into the endometrium, the researchers hope to see if one method is more effective than the others in improving endometrial thickness and increasing the chances of pregnancy.

To participate in this trial, women aged 20-40 who have had previous treatments for intrauterine adhesions and have a history of challenges with fertility may be eligible. Participants will receive one of the three treatments—mechanically engineered exosomes, conventional exosomes, or PRP—and will be monitored for changes in their endometrial health. It’s important for potential participants to be in good overall health and willing to follow the study's guidelines. If you think you might qualify and are interested in joining, you'll need to talk to your doctor about the details and get informed consent.
