The Placenta of Multiple Pregnancy

  • Kurt Benirschke
  • Shirley G. Driscoll


There is evidence that the much increased perinatal mortality of twins is largely the direct result of accidents of placentation. There are many reasons which make us believe that at least monozygous twinning should be considered a pathologic event in man. Moreover, from the detailed study of twin placentas one may deduce a variety of intrauterine circumstances which help to explain morphologic changes in the singleton placenta.
