TL;DR: Results confirm the potential for inhibition of gonadotropin secretion by an effect of corticosterone on the hypothalamohypophyseal axis, but the physiological significance and mechanism of Corticosterone's antigonadotropic effect remain to be established.

TL;DR: In the adrenal gland of a migratory subspecies of the white-crowned sparrow, Zonotrichia leucophrys gambelii as mentioned in this paper, the relative fractional volume of cortical tissue (FCV) and the relative density of sudanophilic material (SI) in the cortical cells correlate with conspicuous annual changes in the microanatomy of the gland.
