The interaction of highly purified pregnant mare serum gonadotropin (PMSG or eCG) has been studied in rat and equine testis homogenates. In the rat studies, unlabeled PMSG was shown to possess both high levels of intrinsic follitropin-like and lutropin-like activity when the inhibition of radioiodinated follitropin and lutropin binding by unlabeled PMSG was studied. Radioiodinated PMSG exhibite...

Biological activity of a synthetic peptide with inhibin-like activity under in vitro and in vivo conditions was compared with three highly potent synthetic lutropin-releasing hormone antagonists. Unlike the synthetic lutropin-releasing hormone antagonists, which effectively inhibited both lutropin and follitropin secretion from the pituitary, the inhibin-like peptide showed a preferential effec...
