Glycogen and Phosphorylase in Bovine and Rat Corpora Lute a, and the Effect of Luteinizing Hormone

Abstract
The presence of glycogen and phosphorylase has been demonstrated in corpora lutea from rat (superovulated rat ovaries) and cow. In vivo administration of LH to pseudopregnant rats caused a significant increase in the activity of the luteal phosphorylase, and a slightly significant loss of total glycogen. The results are discussed in relation to the Haynes-Berthet theory of the activation of steroidogenesis by pituitary tropic hormones. (Endocrinology76: 390, 1965)
