This study was aimed to evaluate the obstetric and perinatal outcomes of women with unexplained infertility following assisted reproductive technology (ART). METHODS: From January 1999 to February 2002, a total of seventy-nine singleton pregnancies which progressed beyond 20 weeks gestation following embryo transfer in women finally diagnosed as unexplained infertility by diagnostic laparoscopy were enrolled in this study. The matched control was spontaneously conceived 172 singleton pregnancies. Retrospectively, we analyzed the obstetric outcome and compared gestational age at delivery, birth weight, Apgar score, and the incidence of perinatal mortality, preterm labor, preeclampsia, gestational diabetes mellitus, and oligohydramnios between two groups. RESULTS: The mean gestational duration of study group was shorter than control group (38.2 +/- 0.5 vs. 39.4 +/- 0.1 weeks, p=0.001). The incidence of gestational diabetes mellitus was significantly higher in the study group (7.6% vs. 1.2%, p=0.01). There was no significant difference in the mean birth weight (3088.1 +/- 86.1 g vs. 3243.8 +/- 37.2 g), the incidence of small for gestational age (10.1% vs. 11.6%), preeclampsia (3.8% vs. 2.3%), oligohydramnios (3.8% vs. 5.8%), preterm labor (7.6% vs. 5.2%), cesarean delivery (45.6% vs. 41.3%), and perinatal mortality (1.3% vs. 0.6%) between the two groups. CONCLUSION: The gestational duration of women with unexplained infertility after IVF-ET was shorter, but the incidence of preterm birth was not increased. And the incidence of gestational diabetes mellitus of study group was higher than that of spontaneously conceived pregnancies.
