Both the pollutantswere able to reduce the hypothalamic extract (HE) or gonadotropin releasing hormone(GnRH) induced pituitary GtH release in vitro. Short term (96h) exposure of the fish tothe pollutants had no significant effect on the gonadal function. ln addition to thedeleterious effect of pollutants on the gonadal steroidogenesis and pituitary gonadotropin release, using [4-14C] cholesterol as a tracer it was found that for 45 days expeure, HgCl2'had an adverse effect on the transport of cholesterol from circulation to ovary.展开更多
