CASTRATION AND THE GROWTH OF MUSCLES IN THE RAT1

Abstract
Rats of the Sprague-Dawley strain were castrated at 36-40 days of age and autopsied 52, 94, 96 and 132 days later. Growth of 29 skeletal muscles and the heart and diaphragm occurred at the same rate as in normal controls and in proportion to the increase in body weight. The N (protein) content of the muscles was unaltered.
