Blood levels of this molecule and its 11-keto derivative are elevated in stoplight parrotfish duringthe initial- to terminal-phase transition.

Injecting passerines with this molecule triggers acatecholamine-driven signaling cascade that induces singing out of season and increases vulnerabilityto cuckoldry by shifting effort from parental investment to extrapair copulations. This moleculeinduces the transformation of the mesonephric duct and undergoes 5 alpha reduction to its dihydroform, which shrinks (*) hair follicles. With its precursor DHEA, this molecule is produced in Leydig cellsexposed to LH. This molecule binds to AR in Sertoli cells, where it allows post-meiotic germ cells todetach when mature, completing spermatogenesis. For 10 points, name this foremost androgen, ahormone that regulates male sexual characteristics and is mimicked by anabolic steroids.
