To assess the effect of advanced maternal age on the obstetrics and neonatal outcome of twin pregnancies.

A retrospective study of 716 dichorionic–diamniotic twin pregnancies delivered at our institute. The study population was divided into two groups: women aged 35–39 years (group A, n = 142) and women aged ≥ 40 years (Group B, n = 48). The control group consisted of women younger than 35 years (group C, n = 516).
