Moderately elevated glucocorticoids increase mate choosiness but do not affect sexual proceptivity or preferences in female gray treefrogs by Baugh, Alexander T., Gall, Megan D., Silver, Stewart C., Bee, Mark A.

“…Glucocorticoids (GCs) are rarely studied in the context of female mate choice, despite the expression of receptors for these products in sexual, sensory and…”
