Abstract

 Polycystic ovary syndrome (PCOS) is a common and complex endocrine disorder affecting women of reproductive age. It is associated with several reproductive and metabolic abnormalities, including irregular menstruation, hyperandrogenism, insulin resistance, obesity, and impaired ovulation. In recent years, oxidative stress has also been recognized as an important factor in the development and progression of PCOS. An imbalance between the production of reactive oxygen species (ROS) and the body's antioxidant defense system can lead to cellular damage, mitochondrial dysfunction, inflammation, and impaired ovarian function.

Natural antioxidants derived from plants, foods, and other biological sources have attracted considerable interest as supportive approaches for managing PCOS. Compounds such as curcumin, resveratrol, quercetin, epigallocatechin gallate (EGCG), N-acetylcysteine, coenzyme Q10 (CoQ10), melatonin, and vitamins C and E have been investigated for their potential to reduce oxidative stress and improve metabolic and reproductive abnormalities. These compounds may act through several mechanisms, including the reduction of ROS, enhancement of antioxidant defenses, improvement of mitochondrial function, regulation of insulin signaling, and modulation of ovarian steroidogenesis.

Among these compounds, kaempferol and CoQ10 are of particular interest because they target different but closely related mechanisms involved in PCOS. Kaempferol, a naturally occurring flavonoid, has antioxidant and anti-inflammatory properties and may influence insulin signaling and ovarian steroidogenesis. CoQ10, on the other hand, plays an important role in mitochondrial energy production and also functions as a lipid-soluble antioxidant. Experimental and clinical findings suggest that these compounds may support ovarian function, improve metabolic parameters, and contribute to better reproductive outcomes.

This review summarizes the role of oxidative stress in PCOS and discusses the potential therapeutic benefits of natural antioxidant-based strategies, with particular emphasis on kaempferol and CoQ10. Their possible mechanisms of action, therapeutic potential, and future applications are also discussed. Although the available evidence is encouraging, further well-designed clinical studies are necessary to establish appropriate doses, bioavailability, safety, and long-term effectiveness. Combining antioxidant-based approaches with lifestyle modification and established PCOS treatments may provide a more comprehensive strategy for managing the disorder.
