Polycystic ovary syndrome is a prevalent, complex endocrine and metabolic disorder primarily affecting individuals with ovaries, representing a major area of clinical and mechanistic investigation in reproductive science and endocrinology. Research into this syndrome focuses on understanding its heterogeneous pathophysiology, which typically involves androgen excess, ovulatory dysfunction, and polycystic ovarian morphology, alongside associated metabolic derangements such as insulin resistance, due to its significant implications for fertility, cardiovascular health, and diabetes risk, necessitating ongoing study of its etiology, diagnosis, and management.
