Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women who have experienced recurrent implantation failure, defined as having transferred at least four good quality embryos across three or more cycles.
✕Probably not a fit
Patients with conditions such as thin endometrium, severe endometriosis, or those using donor oocytes or embryos may not benefit from this study.

What this trial studies
This study evaluates the effectiveness of Preimplantation Genetic Testing for Aneuploidies (PGT-A) in women experiencing recurrent implantation failure. It aims to determine if PGT-A can enhance the ongoing pregnancy rate per transferred embryo and reduce the time to pregnancy and miscarriage rates. The study involves comparing outcomes between patients receiving PGT-A and those receiving standard care. Women with a history of multiple failed embryo transfers will be recruited for this intervention.
Why it matters
Potential benefit: If successful, this approach could significantly improve pregnancy outcomes for women with recurrent implantation failure.
How similar studies have gone: Previous studies have shown promising results with PGT-A in improving pregnancy rates, suggesting this approach may be effective.
