The effect of dapsone in testosterone enanthate-induced polycystic ovary syndrome in rat.

BACKGROUND:One of the most common reasons for infertility is polycystic ovary syndrome (PCOS). PCOS is related to metabolic syndrome, weight gain, type 2 diabetes mellitus, and cardiovascular diseases. Some of the causes of PCOS are dysfunction in the hypothalamus-pituitary-ovarian axis, insulin activity as well as over-activity of sympathetic nerves and elevation in serum levels of pro-inflammatory cytokines. Dapsone, a sulfonamide antibacterial agent, has anti-inflammatory effects such as decreasing inflammatory cytokine levels like TNF-α and IL-1β. METHODS:PCOS was induced by subcutaneous injection of testosterone enanthate (1 mg/100 g) in 21 days old female rats for 35 days. Then, the MET control received metformin (300 mg/kg/day, orally) for 28 days, and to evaluate the efficacy of dapsone (DAP), the DAP group received (12.5 mg/kg, orally) for 28 days. Then, on the last day of the study, the rats were euthanized and the blood was collected to measure the serum levels of hormones, glucose, LDL, LDL/HDL and the left ovaries were dissected for histopathological assay. RESULTS:In the PCOS group, the serum levels of glucose, LDL and LDL/HDL were significantly higher than in the control group (P < 0.001). In addition, the levels of LH, FSH and testosterone changed in the PCOS group compared to the control (P < 0.001). The histopathological morphology changes of the ovary of the PCOS group were significant. Treatment with dapsone and metformin reversed the effects of testosterone in the DAP and MET groups. CONCLUSIONS:Based on the data, dapsone displayed a good antiandrogenic role via decreasing the testosterone levels in PCOS-induced rats.
