Synergism between the Anterior Pituitary Lobe and Chorionic Gonadotropin

Synergism between the Anterior Pituitary Lobe and Chorionic Gonadotropin 

During Eslrus of Mature Females or Hypophysectomized Mature Females Primed with FSH. Here the ovary reacts fully to all gonadot opic hormones including chorionic gonadotropin. 

The gonadotropic effect of chorionic gonadotropin in the organism is based upon the cooperation of a gonadotropic factor furnished by the treated animal s own hypophysis. Without it, only a partial reaction takes place, characterized by 

The cooperatmg factor of the anterior pituitary lobe, the so-called synergist, is presumably the FSH, which is lacking in chorionic gonadotropin. 

On the other hand, pregnant mare blood gonadotropin contains mostly LH, and pituitary gonadotropin contains FSH and LH in varying proportions depending on the species.
