Maternally derived testosterone and 17 beta-estradiol in the eggs of Arctic-breeding glaucous gulls in relation to persistent organic pollutants
It is largely unknown if and how persistent organic pollutants (POPS) affect the transfer of maternal hormones to eggs. This occurs despite an increasing number of studies relating environmental conditions experienced by female birds at the time of egg formation to maternal hormonal effects. Here we...

It is largely unknown if and how persistent organic pollutants (POPS) affect the transfer of maternal hormones to eggs.
