Abstract
Summary: Oral glucose tolerance tests were performed on 50 symptomatic postmenopausal women before and after three months of hormone replacement therapy. All patients were randomly allocated to one of five groups treated with various synthetic or so‐called naturally occurring oestrogens. Therapy produced a significant deterioration of carbohydrate tolerance with sequential preparations containing 100 μg of ethinyl oestradiol or graduated doses of mestranol up to 50 μg. The conjugated equine oestrogen (1·25 mg daily) and oestrogen valerate (2 mg daily) treated groups did not show abnormal glucose tolerance. The decreased glucose tolerance may be due as much to dosage levels as to any metabolic characteristics of the various oestrogens prescribed.
