androgen receptors adrenal androgens life history tradeoffs muscle anabolism and catabolism
摘要:
Androgens have benefits, such as promoting muscle growth, but also significant costs, including suppression of immune function. In many species

摘要:
a positive correlation between yolk precursors in mothers and androgen levels in eggs. Using rockhopper penguins (Eudyptes chrysocome), which produce a two-egg clutch
