Prognostic Value of Progesterone for In Vitro Fertilization (IVF) Outcome (PROG2)
This observational study attempts to investigate the potential role of serum progesterone levels on the day of hCG administration (thus, the end of the follicular phase) on the probability of pregnancy, in patients undergoing IVF with the use of GnRH antagonists and recombinant gonadotrophins.
There has been evidence, that increased serum levels of progesterone are associated with a decreased probability of pregnancy after IVF.
This study will attempt to explore the role of progesterone on the outcome of IVF, by closely monitoring its levels during the late follicular phase.
