Serum Progesterone Levels with The Use of Four Different Types of Vaginal Progesterone in Frozen-Thawed Embryo Transfer Cycles and Related Pregnancy Outcomes [PDF]

International Journal of Fertility and Sterility, 2021
Background: Luteal phase support (LPS) is essential for hormone replacement therapy (HRT) for frozen-thawedembryo transfer (FET). However, the optimal dose and serum progesterone (P4) levels required for pregnancy arecontroversial.
