Summary

This study is collecting cervical mucus from 476 women undergoing IVF or frozen embryo transfer. Researchers will analyze the proteins in the mucus to find markers that indicate when the uterus is most receptive to an embryo. By comparing samples from women who become pregnant with those who do not, they hope to develop a test that helps doctors choose the optimal time for embryo transfer.
