Abstract

Chrysin is a bioflavonoid found in fruits, flowers, tea, honey and wine, which has antioxidant, anti-inflammatory, antiallergic and anticarcinogenic properties. This flavone has also been considered as beneficial for reproduction due its testosterone-boosting potential. Thus, the aim of this study was to evaluate the effects of chrysin on the prostate and gonads of male and female adult gerbils. In addition, a comparative analysis of the effects of testosterone on these same organs was conducted. Ninety-day-old male and female gerbils were treated with chrysin (50 mg kg−1 day−1) or testosterone cypionate (1 mg kg−1 week−1) for 21 days. The ventral male prostate and female prostate were dissected out for morphological, morphometric–stereological and ultrastructural assays. Testes and ovaries were submitted to morphological and morphometric­­–stereological analyses. Chrysin treatment caused epithelial hyperplasia and stromal remodelling of the ventral male and female prostate. Ultrastructurally, male and female prostatic epithelial cells in the chrysin group presented marked development of the organelles involved in the biosynthetic–secretory pathway, whereas cellular toxicity was observed only in female glands. Chrysin preserved normal testicular morphology and increased the number of growing ovarian follicles. Comparatively, testosterone treatment was detrimental to the prostate and gonads, since foci of prostatic intraepithelial neoplasia and gonadal degeneration were observed in both sexes. Thus, under the experimental conditions of this study, chrysin was better tolerated than testosterone in the prostate and gonads.

Additional keywords: fertility, morphology, ovary, prostate gland, testes, testosterone.
