What this trial studies

The ReceptIVFity test evaluates the vaginal microbiome to predict the success rate of IVF or IVF-ICSI treatments. This prospective, non-invasive randomized controlled study aims to compare Shared Decision Making with Physician Decision in determining the likelihood of successful pregnancies. It includes an observational arm for women of non-European origin and focuses on naïve IVF patients aged 18 to 43. The study seeks to reduce unnecessary treatment cycles and improve the efficacy of IVF procedures.

Who should consider this trial

Good fit: Ideal candidates are naïve IVF or IVF-ICSI patients aged 18 to 43 who are willing to provide a vaginal swab for the ReceptIVFity test.

Not a fit: Patients currently using hormonal contraceptives or antibiotics, or those requiring emergency IVF for cancer, will not benefit from this study.

Why it matters

Potential benefit: If successful, this test could enhance the chances of achieving pregnancy for IVF patients by providing tailored treatment recommendations.

How similar studies have performed: Other studies have shown promise in using microbiome assessments to improve IVF outcomes, indicating potential success for this approach.
