Progesterone Supplementation for Frozen Embryo Transfer (P4R Trial)
P4R Trial Summary
This trial is a dose-response study of Endometrin, a progesterone supplement, during in vitro fertilization (IVF). The usual dose of Endometrin is 100 mg two to three times per day. The purpose of this research project is to evaluate the dose response of the Endometrin when determined based on the blood level of progesterone on the day of the FET. The hypothesis is that a woman with low progesterone levels would benefit from a higher dose of Endometrin. PIBF (Progesterone Induced Blocking Factor) levels, a protein found in the blood that could also predict
