day of frozen-thawed embryo transfer (FET) to a hormonally prepared endometrium …

We read with interest the recent publication “Do serum progesterone levels on day of
embryo transfer influence pregnancy outcome in artificial frozen-thaw cycles?” by Volovsky …

A retrospective cohort study was performed to examine whether, in artificial endometrial
preparation for frozen embryo transfer (FET) cycles, progesterone (P) levels the day prior to …
