Optimizing luteal support in frozen embryo transfer cycles

Optimizing luteal support in frozen embryo transfer cycles
There is a paucity of high-quality literature on luteal support in frozen embryo transfer cycles, and there is no consensus regarding the optimal formulation, route, dosage, or duration of progesterone. A Cochrane review in 2010 (1) concluded that “there is insufficient evidence to recommend any one particular protocol.” A more recent meta-analysis (2) drew similar conclusions. Optimizing frozen embryo transfer cycles is of utmost importance, as the number of assisted reproductive technology (ART) cycles performed for banking embryos and oocytes has increased more than 10-fold over the past 10 years (3).
