The morphological examination of the afterbirth of the Danzig quintuplets showed that it was composed of five fused placentas forming one single placenta, of extraplacental fetal membranes forming five separate fetal amniotic sacs and five umbilical cords. The structure of the placentas was very similar and no focal pathological changes were found in their texture. From a morphological point of view all separating membranes speak in favour of a quintovular pregnancy.
