In Vitro Fertilization and Dichorionic-Diamniotic Twin Pregnancies in Nulliparous Women: A Retrospective Cohort Study Comparing Pregnancy Outcomes Between Advanced and Younger Maternal Age Groups

AMA nulliparous women with IVF DCDA twins face elevated risks of fetal growth discordance and surgical blood loss. However, risks of other maternal-fetal complications align with younger counterparts. Targeted prenatal surveillance for twin growth trajectories and intraoperative hemorrhage management may optimize outcomes in AMA populations. These findings support tailored clinical protocols for this high-risk demographic.
