Using an IVF Population to Examine Gestational Age Patterns in Early Miscarriage

The lengths of gestation of 68 confirmed miscarriages from an in vitro fertilization (IVF) program were compared to expected gestational ages from the literature in order to elucidate patterns of early, undiagnosed miscarriages. The peak frequency of miscarriages in the IVF group was earlier than expected, suggesting that the rate of early miscarriage in the general population might be underestimated.
