Preparing and Timing of the Endometrium in Modified Natural Cycle Frozen-thawed Embryo Transfers
The increasing use of FET emphasizes the importance of preparing and timing the endometrium in FET cycles, however there is no consensus on luteal phase progesterone supplementation in mNC-FET and the optimal day of blastocyst…
