Abstract
OBJECTIVE: To investigate obstetric outcomes in singleton pregnancies conceived by in vitro fertilization (IVF) to nulliparous women older than 35 compared to those of their younger counterparts. METHODS: Nulliparous women 35 years and older at delivery conceived by IVF (n = 89) were compared with nulliparous women 34 years and younger at delivery conceived by IVF (n = 48). Data included antenatal data, gestational age at delivery, maternal and neonatal complications and mode of delivery. RESULTS: The incidence of pregnancy-induced hypertension in the younger group was significantly higher than that in the elderly group (13 vs. 3.4%, P = 0.043). There were no measurable differences in other obstetric outcomes such as placental abnormality, premature delivery or neonatal asphyxia between the two groups. CONCLUSION: The current results suggest that obstetric complications in pregnancies conceived IVF are attributed to mechanisms other than those depend on advanced maternal age.
