Integrative Approaches to Ovulation Induction in Polycystic Ovary Syndrome: A Narrative Review of Conventional and Complementary Therapies
Abstract
Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility, with ovulation induction remaining the first-line treatment approach. Although letrozole has emerged as the most effective monotherapy, treatment resistance, side effects, and patient preferences have led to increasing interest in adjunctive or alternative approaches. This narrative review summarizes the current evidence for ovulation induction in patients with PCOS, including conventional pharmacologic agents, such as clomiphene citrate, letrozole, gonadotropins, and insulin-sensitizing agents, as well as complementary therapies, such as acupuncture and Chinese herbal medicine. We also examine emerging adjuvants, such as vitamin D, omega-3 fatty acids, sildenafil, and antioxidants that may enhance clinical pregnancy rates or improve endometrial receptivity. While robust evidence supports the use of letrozole as a first-line agent, complementary and integrative therapies may offer additional benefits, particularly in treatment-resistant or preference-driven contexts. Further high-quality studies are needed to clarify the role of combined therapeutic strategies in optimizing fertility outcomes for women with PCOS.
