Polycystic ovary syndrome (PCOS) is a notoriously heterogeneous, common reproductive disorder associated with many coexisting conditions, including hyperandrogenemia, obesity, insulin resistance and other signs of metabolic dysfunction. PCOS is often diagnosed in the context of anovulatory infertility. However, more recent research disclosed an association of PCOS with increased chances for pregnancy complications, adverse perinatal outcomes and suboptimal long-term health of children born to women with PCOS. This chapter provides an overview of current literature concerning obstetrical complications in women with PCOS, especially increased risk for gestational diabetes (OR 2.7–2.9), hypertensive disorders of pregnancy (including preeclampsia, OR 1.9–4.2) and preterm birth (OR 1.5–2.2). In addition, information regarding children’s outcomes is provided, including birth weight, cardiovascular health and neurodevelopmental health. Finally, pathological pathways including biomarker data in pregnancy and placenta morphology are discussed.
