Description:

Vitellogenin (VTG), an egg yolk precursor, is abnormally produced by male and juvenile oviparous species after exposure to estrogens. Plasma VTG in loggerhead sea turtles ( Caretta caretta ) helped us understand their reproductive maturation and investigate it as a bi omarker of contaminant exposure. The presence of VTG was screened in plasma from 404 loggerheads from the northwestern Atlantic Ocean using a freshwater turtle antibody inwestern blots. The concentra tions of VTG were semiquanti ﬁed using band intensities calibrated to results from a log- gerhead antibody enzyme ‐linked immunoassay. The detection and conce ntrations of VTG were in (from highest to lowest): nesting females, in ‐water adult females, subadult females, smaller females, unknown sex, and males. Logger- heads from this region begin vitellogenesis at ≅77 cm straight carapace length. We classi ﬁed VTG expression as ab-
