“…3). In general, estrogens and particularly estradiol-17/3 have been found to be the most effective steroids in vivo (Redshaw et a1., 1969;Sundararaj and Nath, 1981;van Bohemen et al, 1982), although a weak effect -. -).…”

“…However, their liver is capable of synthesizing and secreting vitellogenin into the blood in response to exogenous estrogen stimulation (6,(17)(18)(19)(20)(21)(22)(23)(24)(25). The response is not as rapid or as strong as in females that are exposed to the same concentrations of estrogen (18).…”

Many environmental pollutants have estrogenic activity in animals. Xenobiotic estrogens include many pesticides and industrial chemicals that bioaccumulate. The impact of these common pollutants on the reproductive success of wildlife may be considerable, particularly in threatened or endangered species. This research examined the use of plasma vitellogenin in males as a biomarker for estrogenic xenobiotics in reptiles and amphibians. Adult male turtles (Trachemys scripta) and frogs (Xenopus laevis) were given ip injections of estradiol-1 7f (E2), diethylstilbestrol (DES), or o,p'DDT (1-chloro-2-[2,2,2-trichloro-1-(4-chlorophenyl)ethyllbenzene) daily for 7 days, and plasma was collected on day 14. The estrogenic activity of each compound was determined by measuring the induction of plasma vitellogenin. Vitellogenin was identified by precipitation, electrophoresis, Western blot, and enzyme-linked immunosorbant assay (ELISA). In both species, estradiol and DES treatments induced the most vitellogenin, whereas DDT treatments induced smaller amounts of vitellogenin in a dose-dependent fashion. These data indicate that induction of plasma vitellogenin in males may be a useful biomarker of xenobiotic estrogen activity in wild populations of reptiles and amphibians. -Environ Health Perspect 103 (Suppl 4):19-25 (1995)

“…Previously, E 2 treatment did not affect the GSI in goldfish (de Vlaming et al, 1977), stinging catfish Heteropneustes fossilis (Sundararaj and Nath, 1981), brook trout (Stegeman et a1 , 1982) , or the cypri ni d fi sh Mi rogrex terrae-sanctae (Varon et al, 1980). E 2 treatment elevated plasma vitellogenin in hypophysectomized winter flounder, but pituitary extracts were requi red to el evate the GSI and stimul ate i ncorporati on of yolk proteins into the ovaries .…”
