Background: Polycystic Ovary Syndrome (PCOS) is a common gynecological, endocrine, and metabolic disorder of unknown etiology. It is a complex endocrine illness that is marked by reduced development of follicles, hyperandrogenemia, insulin resistivity, infertility, increased luteinizing hormone, obesity, and augmented cystic ovaries. Objective: This review aimed to assess the efficacy of herbal and bioactive components of medicinal plants for mitigating PCOS. Materials and Methods: To conduct this review, keywords like “herbal treatment”, “ayurvedic treatment”, “bioactive components of medicinal plants”, “polycystic ovary syndrome”, and “PCOS” were used to search for various articles in search engines such as Google Scholar, PubMed/MEDLINE, Web of Science, Scopus, Elsevier from 1992 to 2023. Results: More than 28 relevant studies were found and were briefly described in this review. According to the evidence, medicinal plant extracts containing phytoestrogens and these herbal treatments in animal models of PCOS were used to decrease hyperandrogenism, restoration of abnormalities in serum sex steroid profile, ratio of LH: FSH, steroidogenic enzymes, cardiovascular parameters, insulin resistance, ovary weight, lipid profile, and estrous cycles. Conclusion: The results of this review revealed the variability and efficacy of phytoestrogen activity and herbal treatments associated with PCOS disorder which can be partly effective. These findings may represent an opportunity to investigate and discover new bioactive components of medicinal plants which may help future studies on the etiology, pathophysiology and treatment of PCOS disorder.
