Perinatal outcomes of elderly primiparous dichorionic twin pregnancies conceived by in vitro fertilization compared with those conceived spontaneously.

OBJECTIVE

To examine the perinatal outcomes of elderly primiparous dichorionic twin pregnancies conceived by in vitro fertilization (IVF) compared with those conceived spontaneously.

METHODS

Data were collected from primiparous women aged 35 and older with dichorionic twin pregnancy conceived by IVF (n = 64) and those conceived spontaneously (n = 87). Data included antenatal data, gestational age at delivery, obstetric complications such as preeclampsia, gestational diabetes, placental previa and placental abruption, mode of delivery, birth weight, birth weight discordance, fetal demise, Apgar score at 1 min and umbilical areterial pH.

RESULTS

The rate of elective Cesarean sections in the group conceived by IVF was significantly higher than that conceived spontaneously. There were no significant differences in other variables between the two groups.

CONCLUSIONS

The current results did not support the IVF-related risks of elderly primiparous dichorionic twin pregnancies.
