Effects of human chorionic gonadotropin (hCG) on pituitary prolactin (PRL) in the lizard, Uromastix hardwickii.
A consideration of the data indicates that 45 IU human chorionic gonadotropin (hCG) treated lizard pituitaries, extracted after 30 and 60 minutes gave a mean crop-sac diametric response of 2.15 cm and 2.13 cm respectively in pigeons. The role of hCG in accelerating the synthesis of pigeon's milk is extra ordinary, and it seems that hCG exhibits this effect via lizard pituitary lactotrophs.
