IMPORTANCE The prevalence of oocyte donation for in vitro fertilization (IVF) has increased in the United States, but little information is available regarding maternal or infant outcomes to improve counseling and clinical decision making. OBJECTIVES To quantify trends in donor oocyte cycles in the United States and to determine predictors of a good perinatal outcome among IVF cycles using fr...

BACKGROUND Conflicting results have been published about the determinants of pregnancy after oocyte donation (OD). We used the OD model to determine predictive factors of pregnancy in the recipient after frozen-thawed embryo transfer (FTET) in a specific series where all the embryos were cryopreserved without any prior selection for fresh transfer. METHODS We report a retrospective study in a...
