In Vivo Exposure to Bisphenol-A Altered the Reproductive Functionality in Male Coturnix Coturnix Japonica

Abstract

Bisphenol-A, is one of the most characterized endocrine disruptors on the reproductive functions in humans and animals. We have previously reported in vitro and in vivo effects of bisphenol-A on functional role of sperm in chicken. Here, the effects of 1 and 5 mg/kg bisphenol-A daily administered by gavage for 3 wk to adult male Japanese quails on reproductive functionality was investigated. Cloacal index and foam frequency were greatly reduced at high dose. Sperm quality attributes were affected at both doses. Sperm quality attributes were affected at both doses. Alkaline phosphatase showed most significant reduction among seminal enzymes. Dose dependent response (P < 0.01) of bisphenol-A was noticed with modulating testosterone concentrations at low and high doses. Disturbances regarding fertility and hatchability traits were prominent in high and low dose groups. The current study confirms the compromising actions of bisphenol-A on reproductive success in male Japanese quails at lower doses that are considered to be safe (50 mg/kg BW/d) under in vivo exposure module. These results indicate higher sensitivity of quails to bisphenol-A toxicity and explores the possibility of using quail subjects as an accurate toxic indicators.
