The effect of subclinical hypothyroidism on hormonal and metabolic profiles and ovarian morphology in patients with polycystic ovary syndrome: a cross-sectional study.
Gynecological Endocrinology 2024 December
OBJECTIVES: Polycystic ovary syndrome (PCOS) and subclinical hypothyroidism (SCH) are prevalent gynecological conditions. However, the interrelationship between the two remains elusive. This study aims to elucidate the association between these conditions and determine the potential impact of SCH on the physiological and metabolic characteristics of patients with PCOS.
METHODS: This cross-sectional study enrolled 133 patients with PCOS from our Hospital. Participants were categorized into two groups: those with PCOS + SCH ( n = 58) and those with PCOS ( n = 75). Serum hormonal levels, metabolic markers, ovarian volume, and follicle count were compared between the groups.
RESULTS: There was a significant difference in BMI between the two groups, with a higher prevalence of obesity in the PCOS + SCH group ( p = .014). Compared to the PCOS group, patients with PCOS + SCH had significantly higher levels of TSH ( p < .001), triglycerides ( p = .025), and HOMA-IR ( p < .001), while LH levels were significantly lower ( p = .048). However, multivariate linear regression analysis revealed that TSH, triglycerides, LH, and HOMA-IR were not determinants for the occurrence of SCH in patients with PCOS. Additionally, there was a notable reduction in follicle count in the left ovary for the PCOS + SCH group compared to the PCOS group ( p = .003), and the overall follicle diameter of the PCOS + SCH group was also smaller ( p = .010).
CONCLUSION: SCH may exert effects on the physiological and metabolic profiles of patients with PCOS. Further investigation into the relationship between these disorders is warranted to delineate their clinical implications.
