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.
