Effect of castration on the appearance of diabetes in NOD mouse.


To examine the influence of sex hormones on the appearance of overt diabetes in NOD mice, oophorectomy and orchiectomy were performed. Castrated males showed a high incidence of diabetes. The time course of onset was similar to that of the intact females. On the other hand, castrated females showed a intact-male pattern of onset with a low incidence. Clinical determinations demonstrated a close similarity between spontaneous and castration-induced diabetes. These data suggest that sex hormones modulate the expression of overt diabetes in NOD mouse, i. e. androgens have at least a suppressive effect.
