The difference between these two types of aboion is of fundamental impoance. The lack of development of fetal structures defines a subset of aboions of genetic origin. In contrast, the early interruption of fetal life is a complex phenomenon with multiple etiologies. Therefore, the couples with blighted ova do not require extensive work up, whereas patients who have aboed cytogenetically normal fetuses need an extensive search for non genetic factors responsible for the pregnancy loss.
