Effects on growth and body composition of androgen deprivation by castration or autoimmunization to LH-releasing hormone in the male rat under conditions of controlled food intake

摘要: The effects of endogenous gonadal hormones on the regulation body composition and energy retention have been investigated under conditions controlled food intake. Male female rats were fed same amount from weaning to 82 days age. carcases males contained more protein, less lipid yielded ash than females, but they had total in their as females. In a second experiment, male sham-operated or castrated at 19 then equal amounts weaning. At 40 days, intact did not differ carcase content nor composition. protein retained rats. By 131 difference was larger lipid, gave age with similar intake, differences between females considerably males. third 1 day post partum experiment days. Both sham-castrated grew well operated direction greater magnitude later age.(ABSTRACT TRUNCATED AT 250 WORDS)
