POTENTIAL ESTROGENIC EFFECTS OF BISPHENOL-A IN MALE RATS AND BENEFICIAL ADMINISTRATION OF SOME ANTIOXIDANTS

Bisphenol-A is a chemical compound which is used primarily as a monomer in the manufacture of numerous chemical products. The objective of this study was to evaluate potential harmful effects of bisphenol-A on reproductive system of male rats and was designed to clarify the ability of zinc or selenium to improve this perturbation in the reproductive function of rats.As a result of bisphenol-A treatment, number of sperms, testis total protein, glutathione and glutathione peroxidase were decreased significantly. This effect was concomitant with a significant decrease in serum testosterone level. On the other hand, bisphenol-A caused a significant elevation in the abnormality of sperm (sperm malformed head or tail or head and tail) and testis total lipid. However, a significant increment was obtained in serum FSH, LH, PRL, E2 and progesterone levels when compared with their corresponding normal control rats.Moreover, the administration of zinc or selenium to treated rats with bisphenol-A rats led to a remarkable amelioration in all previous parameters
