Background: Polycystic ovary syndrome (PCOS) is the most common endocrine disorders in reproductive age women. These women confer with complications of pregnancy such as gestational diabetes, pregnancy-induced hypertension, preeclampsia and neonatal complications such as small for gestational diabetes (SGA) are more prevalence in women with PCOS. The aim of this study was to evaluate the incidence of complications associated with PCOS in pregnant women.

Methods: This was an observational and prospective study which recruited 205 pregnant women with PCOS from Imam Khomeini Hospital, Ahvaz Jundishapur University of Medical Sciences (AJUMS) between 2013 and 2014. Inclusion criteria were women with PCOS and gestational age over 20 weeks. The demographic and clinical variables including mother's age, body mass index (BMI) and conditions of pregnancy including pregnancy-induced hypertension, preeclampsia, gestational diabetes and overt diabetes and neonatal complications such as preterm labor (PTL), SGA and intrauterine fetal death (IUFD) were recorded.

Results: The prevalence of hypertension disorders, preeclampsia, gestational diabetes and overt diabetes were observed in 44 (21.5%), 18 (8.8%), 29 (14%) and 22 (11%) patients, respectively. The history of familial diabetes was shown in 28 patients (13.6%). In addition, the history of pregnancy induced hypertension was reported in 25 patients (12.1%). Only 6 patients (2.9%) had history of gestational diabetes. Among neonatal complications due to PCOS, SGA with 15.3% and then PTL with 12.6% had highest prevalence. IUFD was shown only in 2 patients.

Conclusion: Pregnant women with PCOS are at the higher risk for pregnancy and neonatal complications. Specifically, these women should be evaluated for pregnancy induced hypertension during pregnancy than others.
