while castration results in greater endocytosis by principal cells ( moore and bedford , '79 ) , many of their early structural changes following androgen withdrawal ( disappearance of vesicles from the cell apex , reduction in rough endoplasmic reticulum , a drop in the volume of the golgi cisternae and increase in lysosome content ) seem indicative of inhibition of a secretory function .
