An antibody against luteinizing hormone-releasing hormone (LHRH) as well as naloxone, an opioid antagonist, were added to the chorioallantoic membrane (CAM) of 11.5- and 14.5-day-old male chick embryos and plasma testosterone (T) concentrations were determined. This protocol was designed to demonstrate: (1) Whether LHRH is essential in the regulation of the adenohypophyseal-testicular axis in the male embryo and (2) if LHRH is operative in this unit's function, are opiatergic pathways involved… CONTINUE READING
