John T. Matschiner, Allan K. The effect of sex hormones on vitamin K deficiency was studied in intact and castrated male and female rats. The onset of vitamin K deficiency after castration was enhanced in the female and retarded in the male. Castrated male and female rats developed vitamin K deficiency to about the same extent. Plasma prothrombin levels in castrated male and female rats fed vitamin K-deficient diet dropped after the injection of testosterone and rose or remained high after the injection of estradiol.
