Summary

This study aimed to create a library of biological samples and clinical data from 250 women with unexplained infertility or low ovarian reserve. Researchers collected blood, DNA, vaginal swabs, and fluid from egg retrieval to help future studies find markers that predict pregnancy success with IVF. The study was terminated early, so the library may be incomplete.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this library could help researchers find new biomarkers to predict which women with unexplained infertility are most likely to get pregnant through IVF.
What could go wrong
This study only collected samples and did not test any treatment. It was terminated early, so the library may be incomplete and may not lead to any new discoveries.
