Evaluating a biomarker's ability to predict embryo implantation success

Study to Detect the Predictive Capacity of a Composite Biological Marker in the Success of Embryonic Implantation in Fertilization Treatments in Vitro (IVF): Seedchrony Pilot.

Not applicable Interventional Manina Medtech · NCT06259084

This study is testing if measuring a specific marker in the uterine fluid can help predict whether frozen embryos will successfully implant in women undergoing IVF.

What this trial studies

This clinical investigation aims to assess whether the concentration of a specific intrauterine biomarker in the uterine fluid can predict the success of embryo transfer during In Vitro Fertilization (IVF). The study will recruit 80 volunteers undergoing frozen embryo transfer cycles with high-quality blastocysts. Using an investigational device, the biomarker levels will be measured the day before and on the day of embryo transfer, while also collecting various clinical variables related to the IVF cycle. The primary focus is to establish a relationship between the biomarker concentration and the outcome of the embryo transfer.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 37 undergoing their first IVF cycle with high-quality frozen blastocysts.

Not a fit: Patients with severe male factor infertility or certain uterine pathologies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly improve the success rates of embryo transfers in IVF, leading to higher pregnancy rates.

How similar studies have performed: While this approach is exploratory, similar studies evaluating biomarkers in IVF have shown promise, though this specific method is novel.
