Genistein Blunted Detrimental Effects of Polycystic Ovary Syndrome on the Ovarian Tissue of Rats by Improving Follicular Development and Gonadotropin Secretion
OBJECTIVE: Polycystic ovary syndrome (PCOS) is a common cause of female infertility worldwide. It has been shown that genistein, a natural isoflavone, may influence follicular competence via the production of gonadotropins in women with PCOS. The current study aims to evaluate the effects of geniste...

Sumario: | OBJECTIVE: Polycystic ovary syndrome (PCOS) is a common cause of female infertility worldwide. It has been shown that genistein, a natural isoflavone, may influence follicular competence via the production of gonadotropins in women with PCOS. The current study aims to evaluate the effects of genistein on the ovarian tissue of rats with PCOS. METHODS: Thirty female Wistar rats were randomly divided into the following four groups: Control; PCOS (rats received 2 mg/kbW estradiol valerate); Genistein (rats given 1 mg/kg BW of genistein for 14 days); and Genistein + PCOS. All animals were slaughtered under anesthesia and blood samples were collected for biochemical analysis. Follicular morphology was analyzed based on histologic examination. RESULTS: Histologic examination exhibited enhanced follicular atresia at various stages in the rats with PCOS compared to controls (p<0.001). Induction of PCOS caused significant reduction in gonadotropin levels and steroid hormone levels consistent with insulin resistance (p<0.01). Data showed that 14-day administration of genistein might improve follicular morphology in rats with PCOS (p<0.001). Genistein treatment increased the production of gonadotropins and steroid hormones and alleviated insulin resistance in Rats with PCOS (p<0.001). CONCLUSIONS: This study indicated that genistein treatment exerted a beneficial effect on the ovarian tissue of rats with PCOS by improving follicular growth and hormone balance. |
