Summary
10 papers analyzed
Some studies suggest that women with PCOS have a significantly increased risk of pregnancy complications such as hypertension, pre-eclampsia, gestational diabetes, and preterm birth, while other studies indicate that when age and weight differences are negligible, PCOS is not associated with a higher risk of pregnancy complications.

Pregnancy Outcomes in Women with Polycystic Ovary Syndrome (PCOS)
Increased Risk of Pregnancy Complications in PCOS
Women with polycystic ovary syndrome (PCOS) face a significantly higher risk of various pregnancy complications compared to women without PCOS. Studies have consistently shown that PCOS is associated with a higher incidence of gestational diabetes mellitus (GDM), pregnancy-induced hypertension (PIH), preeclampsia, and preterm birth . Specifically, women with PCOS have a 3-4 times higher risk of developing pregnancy-induced hypertension and preeclampsia, a 3-fold increased risk of gestational diabetes, and a 2-fold higher chance of premature delivery .
Neonatal Complications and Long-term Child Health
The complications extend beyond pregnancy, affecting neonatal outcomes as well. Babies born to mothers with PCOS are more likely to be admitted to neonatal intensive care units (NICU) and have a higher perinatal mortality rate . Additionally, there is evidence suggesting that offspring of women with PCOS may have an increased risk of future metabolic and reproductive dysfunctions . This highlights the importance of monitoring and managing pregnancies in women with PCOS to mitigate these risks.
Role of Obesity and Insulin Resistance
Obesity and insulin resistance, common features of PCOS, are significant contributors to the increased risk of pregnancy complications. These factors exacerbate the likelihood of developing GDM, PIH, and preeclampsia . The metabolic abnormalities associated with PCOS, such as hyperandrogenism and insulin resistance, are believed to play a pivotal role in these adverse outcomes .
Impact of Lifestyle Interventions
Lifestyle interventions, including cognitive behavioral therapy, healthy diet, and exercise, have shown promise in reducing some of the pregnancy complications associated with PCOS. A study comparing a three-component lifestyle intervention to usual care found lower rates of gestational diabetes, hypertensive disorders, and preterm birth in the intervention group, although the differences were not statistically significant. This suggests that lifestyle modifications may help improve pregnancy outcomes in women with PCOS.
Placental Dysfunction and Developmental Programming
Emerging research indicates that placental dysfunction may be a key factor in the adverse pregnancy outcomes observed in women with PCOS. Gestational androgen excess and insulin resistance, hallmarks of PCOS, may contribute to placental dysfunction, leading to higher rates of maternal-fetal complications. This placental compromise could also play a role in the developmental programming of long-term health risks for the offspring.
Conclusion
Women with PCOS are at a heightened risk of various pregnancy and neonatal complications, primarily due to underlying metabolic and hormonal imbalances. Effective management strategies, including lifestyle interventions and close monitoring, are essential to mitigate these risks. Further research is needed to fully understand the mechanisms behind these complications and to develop targeted interventions to improve outcomes for both mothers and their children.
