Many IVF clinics use endometrial thickness as a predictive factor for IVF outcomes, as research has shown a positive association between endometrial thickness and favorable IVF outcomes. A thickness of 6-8 mm is often used as a cut-off in for the decision of whether or not to transfer an embryo in both fresh and frozen cycles. However, prior studies investigating the relationship between a thin endometrium and IVF outcomes have overwhelmingly been performed in fresh cleavage stage embryo transfers. Given the recent trend toward the transfer of frozen blastocyst transfers, we aimed to determine whether endometrial thickness predicts live birth in both fresh and frozen blastocyst stage single embryo transfers.
