Effects of gonadal hormones on the lipid contents of the frogRana esculenta

Summary The effects of exogenous gonadal hormones on the lipid contents of the liver and ovary and also on water content in the frog,Rana esculenta, were studied. Estrogen treatment significantly enhanced, whereas testosterone treatment reduced, the lipid and cholesterol contents. Water content of the frogs increased significantly after treatment by either hormone.Acknowledgment.
