Abstract
There is no doubt that the complexity of human twinning cannot be understood without knowledge of placentation and that placental examination is vital to this endeavor. Examination of the placenta contributes to the determination and confirmation of zygosity as well as an understanding of abnormal events. With the advent of assisted reproductive technology, twins and higher multiple gestations are becoming more common. Since multiple gestations represent a disproportionate portion of complications with higher rates of prematurity, perinatal morbidity, perinatal mortality, and malformations than singletons, placental examination has become especially important.
