The retardation of fetal growth in twin as compared to singleton gestations may be due to maternal and/or placental factors. The separate birthweights and related placental weights of 487 dichorial twin pairs were recorded, and the heavier placental weights of firstborns in comparison with second-borns were found to be related to the heavier birthweights of firstborns compared to second-borns. The lighter placental weights of firstborns compared to second-borns were found to be related to the lighter birthweights of firstborns compared to second-borns. Obviously, the placenta itself may may very well be the cause of the retardation of fetal growth in twin gestations.
与单胎妊娠相比，双胎妊娠中胎儿生长迟缓可能是由母体和/或胎盘因素导致的。记录了487对双绒毛膜双胎的各自出生体重及相关胎盘重量，发现与第二个出生的胎儿相比，第一个出生的胎儿胎盘重量较重，且其出生体重也较重。与第二个出生的胎儿相比，第一个出生的胎儿胎盘重量较轻，其出生体重也较轻。显然，胎盘本身很可能是双胎妊娠中胎儿生长迟缓的原因。
