Objective: To assess the status of thyroid disorders in polycystic ovarian syndrome (PCOS). Methods: This prospective hospital-based case-control study involved most outpatients in the age group of 13–45 years who visited the Obstetrics, Gynecology, and infertility clinic at Baghdad Teaching Hospital with complaints of hirsutism and/or oligomenorrhea or infertility. This study included 70 patients, including 50 with PCOS (PCOS group) and 20 without (control group). Results: The PCOS group exhibited significantly higher mean thyroid stimulating hormone level (3.9 vs. 3.1 µIU/L), luteinizing hormone level (15.2 vs. 4.7 mIU/mL), and body mass index (28.6 vs. 24.9 kg/m2; all, p<0.001) and a non-significantly higher follicle-stimulating hormone level (9.2 vs. 5.2 mIU/L) than the control group. Conclusion: Our results demonstrate a higher prevalence of euthyroidism among women with PCOS.
