Abstract
THIS paper embodies the continuation of our studies on en dome trial glycogen, based primarily on the application of the methods of Petersen and Rose using anthrone (1). A previous paper by Sabin and Latour (2) described the application of this reagent with definite color reaction as a qualitative test for detection of secretory-phase endometrium. A second paper by Payne and Latour (3) described the application of the photoelectric quantitative measurements of this color reaction to the estimation of glycogen levels in normal endometrium during the cyclic changes, as well as in the abnormal endometrium. The main purpose of this paper is to report the continuation of the application of the quantitative measurements in cyclic normal endometrium, in order to validate the physiologic curve presented by Payne and Latour (3), which was based on a relatively small number of patients. The second purpose is to stimulate interest and discussions on the possible purpose of glycogen in the endometrium and to determine its relationship to implantation.
