32 endometrial biopsies, 22 of which had used the IUD for 1-20 years or more and 10 cases with normal menstrual cycles used as controls were studied by means of histochemical methods. As compared with controls, the activities of succinic dehydrogenase, alkaline phosphatase, thiamine pyrophosphatase, glucose-6-phosphatase were more or less decreased and the amount of glycogen reduced in most of the endometrial blood vessels in IUD users. However, no significant difference between the activity of acid phosphatase and nonspecific esterases of the IUD users and control groups had been found. Results suggest that the dilatation, defect, and rupture of endometrial microvascularity in IUD-exposed users may be related to the changes of enzymes and glycogen. (author's modified)
