A total of 116 cases of multiple pregnancy has been observed in a 5-year period. MZ twin pregnancies appear to be significantly increased in the maternal age group 31-35. Also significant is the higher frequency of abnormal cycles in MZ twin pregnancies. Family incidence of twins is more significant in mothers of DZ as compared to MZ twins.
