Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include women with primary infertility who are undergoing assisted reproduction treatment and have an altered endometrial immune profile.
✕Probably not a fit
Patients with uterine pathologies, active endometrial inflammation, or certain autoimmune conditions may not benefit from this treatment.

What this trial studies
This study investigates the effects of intrauterine administration of autologous peripheral blood mononuclear cells (PBMC) on the populations of endometrial cells in women experiencing infertility. The research aims to understand how these immune cells can alter the endometrial environment, potentially enhancing embryo implantation success during assisted reproduction treatments. By focusing on the immune profile of the endometrium, the study seeks to provide insights into improving IVF outcomes through cellular composition changes. Participants will receive PBMC treatment to evaluate its impact on their endometrial health.
Why it matters
Potential benefit: If successful, this approach could significantly improve IVF success rates for women with specific infertility issues related to endometrial health.
How similar studies have gone: Previous studies have reported positive outcomes with similar approaches, suggesting potential for success in this novel application.
