¬¬¬Lycopene Protects Testes and Epididymal Sperm in BPA Exposed Adult Sprague-Dawley Rats
Abstract: Bisphenol A (BPA) is ubiquitous and persistent environmental contaminant. Previous studies proved that BPA disrupt hypothalamic–pituitary–gonadal axis and oxidative balance. Numerous studies have clearly been reported that oxidative stress leads to male infertility by affecting testes and spermatozoa. On the other hand, lycopene has beneficial role on testes and spermatozoa by reducing the oxidative stress. Therefore, this study was conducted to delineate the protective role of lycopene by acting against …
