Summary

This observational study looks at embryos from IVF that are not used for pregnancy to find molecular patterns related to embryo quality. Researchers hope to learn why some embryos are healthy and others are not, which could improve future fertility treatments. About 150 patients will donate their discarded embryos, and their own IVF care will not be changed.
