Polycystic Ovary Syndrome: Endocrine and Metabolic Pathophysiology with Clinical Management Implications
Overview
This paper examines Polycystic Ovary Syndrome (PCOS) as a complex reproductive and endocrine disorder affecting women of reproductive age. It discusses the pathophysiology of PCOS including hormonal imbalances, insulin resistance, and ovulatory dysfunction, while analyzing its systemic implications for metabolic health and cardiovascular risk. The paper emphasizes the multidisciplinary approach required for managing this condition through lifestyle modifications and pharmacological interventions.

Module 6 Discussion Post: Polycystic Ovary Syndrome (PCOS)
One disorder of the reproductive system that I found particularly interesting is Polycystic Ovary Syndrome (PCOS). PCOS affects the female reproductive system, especially the ovaries, and is one of the most common causes of infertility in women of reproductive age (Teede et al., 2018). It is characterized by hormonal imbalance involving increased androgens, disrupted luteinizing hormone (LH) and follicle-stimulating hormone (FSH) ratios, and irregular ovulation.
PCOS typically manifests as irregular or absent menstrual cycles, excess facial or body hair (hirsutism), acne, weight gain, and difficulty conceiving. On a physiological level, the ovaries often contain multiple immature follicles that fail to develop properly, leading to a “polycystic” appearance on ultrasound (Azziz et al., 2016). Insulin resistance is also commonly involved, which further increases androgen production and worsens symptoms.
This disorder affects multiple body systems beyond reproduction, including metabolic health. Women with PCOS have a higher risk of type 2 diabetes, cardiovascular disease, and endometrial hyperplasia due to prolonged unopposed estrogen exposure. Treatment typically includes lifestyle changes such as diet and exercise, insulin-sensitizing drugs like metformin, and hormonal contraceptives to regulate menstrual cycles and reduce androgen levels. An interesting fact is that PCOS is not only a reproductive disorder but also a complex endocrine and metabolic condition, making its management multidisciplinary.
