Abstract
Testosterone propionate and purified growth hormone maintained glycogen levels above that of the controls in several skeletal muscles of fasted, hypophysectomized female rats. Testosterone increased the glycogen level of these muscles in intact female rats as well. When combined injns. of testosterone as growth hormone were administered to hypophysectomized female rats, the amt. of glycogen deposited could be accounted for by the sum of the effects achieved with the hormones when given separately. A possible seasonal difference in basic glycogen levels was observed in some muscles of fasted, hypophysectomized female rats.
