Abstract

Antioxidants can be used as adjuvant treatment of polycystic ovary syndrome (PCOS). Melatonin (MT) is one of the antioxidant that is used nowadays. Objective: In this study, the effect of MT on the histological changes of ovary in the experimental model of polycystic ovary syndrome is investigated. Methods: In this study 30 immature female NMRI mice were divided into 5 groups including: (1) control group received distilled water, (2) received a dose of 10. mg/kg MT for 5. days, (3) received Dehydroepiandrostenedione (DHEA) at a dose of 6. mg/kg for 20. days to induce PCOS, (4) after induction of PCOS received MT at a dose of 10. mg/kg for 5. days, and (5) received 6. mg/kg DHEA and 10. mg/kg MT for 20. days simultaneously. Results: The evaluation of ovarian tissue characteristics such as the granulosa layer, theca, number and diameter of cysts and follicles was performed. PCOS caused a significant reduction in the number of antral follicles and corpus luteum and an increase in the number of primordial, primary, pre-antral and cystic follicles in comparison with the control group (P. <. 0.05). Moreover, MT resulted in a significant increase in the granulosa layer thickness in group 4 (P. <. 0.001), and group 5 (P = 0.001) and a significant reduction in the thickness of theca layer between groups 4 and 5 compared with group 3 (P. <. 0.001). Conclusion: These findings indicate that MT have a protective effects on polycystic ovary damages induced by DHEA, although the mechanism is unclear. It is likely that this is happening by reducing oxidative damage. © 2017.
