Insects representing 5 different orders contain androgen and estrogen-like substances as determined by radioimmunoassay. Estradiol and estriol have been identified by gas chromatography-mass spectrometry. The presence of these steroids in insects suggests that the vertebrate sex hormones have an ancient evolutionary history.
