Popis: CONTRIBUTIONS to the knowledge of the influence of reproduction, especially that of the individual reproductive hormones upon the growth rate in the female, have not been numerous. In most of these investigations the effects of ovariectomy or of pregnancy were generally studied. Evidence that ovariectomized rats grow more rapidly than virgin controls has been presented by Stotsenburg (1913), Slonaker (1930), Freudenberger and Billeter (1935), Freudenberger and Howard (1937), Freudenberger and Hashimoto (1937–38 and 1939) Bogart et al. (1940), and Tang (1941). Pronounced differences in the rate of growth were shown to exist between pregnant and virgin female rats of the same age by Slonaker (1927), Cole and Hart (1938) and Bogart et al. (1940). The effects of pregnancy, pseudopregnancy (Hart and Cole, 1939) and ovariectomy upon growth indicate that the reproductive hormones may be directly or indirectly involved.
