Effect of Parathion, an Organophosphorous Compound on estrous cycle of female Rattus ratus

Abstract

20 adult female rats Rattus ratus were exposed with 5 ppm of parathion (organophosphorus compound) for 60 days and their vaginal smears were examined to observe the estrous cycle.It is very axiomatic from the results that estrous cycle has been disrupted in experimental animal treated with parathion, which has been observed by direct fall in number of estrous cycles in treated animal as compared to control.
