Clinical trials: Frozen Embryos
Progesterone Supplementation
Optimal Length of Progesterone Supplementation Before the Transfer of Cryopreserved (Frozen)-Thawed Day 3 Embryos in an Artificial Cycle With Exogenous Estrogen and Progesterone
Cryopreserved-thawed embryos are often replaced in an artificial cycle, in which the endometrium is prepared by exogenous estrogen and progesterone with or without the use of GnRH agonist downregulation.
