Background: Polycystic ovary syndrome is a prevalent endocrine disorder and a major cause of infertility. Although lifestyle modification is emphasized in both Persian and modern medicine, the role of sleep is often overlooked. This review investigates the role of sleep in different patterns of PCOS management from both perspectives.
   Methods: The study is a narrative review. Literature from both Persian and modern sources was analyzed regarding the impact of various factors on PCOS, with a focus on the impact of sleep. Modern databases were searched with defined keywords and criteria.
   Results: Modern studies often describe sleep disorders as consequences of PCOS. However, Persian medicine considers poor sleep a potential cause of the disease, highlighting the need for personalized sleep recommendations.
   Conclusion: It is recommended that sleep, like diet and exercise, be included in the lifestyle management of PCOS. For this purpose, more clinical studies are needed to prove the connection between improving sleep and reducing disease outcomes.
