The rate of early intrauterine growth in twin gestation
Abstract:
With the use of specimens obtained by induced abortion, the relationships between crown-rump length on the one hand and body weight and menstrual age on the other were investigated in 43 twin fetuses with menstrual ages between 8 1/2 and 21 weeks. This study indicates that the body weight of twins in comparison with length is the same as that of singletons, an indication of the fact that they are not growth retarded. On the other hand, the average crown-rump length when compared with menstrual age is somewhat less than that of singleton fetuses. The possible implications of these findings are discussed in the light of prevailing concepts concerning the growth of twins.
