Medically conceived twins have an increased risk of preterm birth

Compared with naturally conceived twins, twins resulting from subfertility treatment have a slightly decreased gestational age at birth and an increased risk of preterm birth. Verstraelen and colleagues (p 1173) carried out a population based cohort study of more than 4300 twin pairs and found an odds ratio of 1.6 (95% CI 1.4 to 1.8) for preterm birth after artificial induction of ovulation. The risk is however limited to mild preterm birth, which is mainly due to dizygotic twinning after subfertility treatment.
