FSH, LH, lipid and adipokines in Polycystic Ovary Syndrome: Clinical biochemistry insights for diagnosis and management.

Polycystic Ovary Syndrome (PCOS) is a common endocrine syndrome characterized by hormonal imbalances, metabolic disturbances, and clinical symptoms. The pathophysiology of this syndrome involves disruptions in hormonal signaling, particularly changes in levels of luteinizing hormone (LH), and follicle-stimulating hormone (FSH) which can lead to anovulation and infertility. Additionally, insulin resistance and dysfunctional adipose tissue are other complicating factors of this condition. Biochemical markers such as FSH, LH, lipid profiles, and adipokines (like leptin and adiponectin) are crucial for diagnosing PCOS and assessing its severity. In PCOS patients, elevated LH levels relative to FSH are typically observed, and lipid abnormalities increase the risk of cardiovascular diseases. Diagnosing this syndrome usually requires comprehensive biochemical tests to confirm hyperandrogenism and insulin resistance. Management strategies include lifestyle modifications and pharmacological interventions aimed at correcting hormonal imbalances and dyslipidemia. Monitoring treatment outcomes through biochemical markers is essential for evaluating therapeutic efficacy. This review article examines the roles of FSH and LH hormones, lipids, and adipokines in the diagnosis and management of PCOS, emphasizing the importance of clinical biochemistry in improving diagnostic and treatment methods for this disorder. Furthermore, research into identifying emerging biomarkers for early diagnosis and new therapeutic targets is suggested.
