title: Effect of contraceptive steroids on arginine-stimulated glucagon and insulin secretion in women. III. Medroxyprogesterone acetate.
abstract: The effect of medroxyprogesterone acetate (MPA) on basal circulating lipids, arginine-stimulated glucagon and insulin secretion, and glucose tolerance was studied in normal women. After 5 days of oral MPA treatment (10 mg/day), there was a small but significant decline in basal circulating triglycerides. No changes were observed in fasting plasma concentrations of cholesterol, free fatty acids, glucagon, insulin, or glucose; in the plasma glucagon, insulin, or glucose responses during L-arginine infusion; or in the plasma insulin or glucose responses during oral glucose tolerance tests. There was no correlation of any of these parameters with the observed decline in fasting plasma triglyceride concentrations. These results confirm previous reports of no consistent changes in lipid or glucose homeostasis in women using derivatives of 17alpha-acetoxyprogesterone derivatives for contraceptive purposes, and suggest that MPA may be a suitable alternative for those women who develop hyperlipemia or glucose intolerance when they use contraceptive agents which contain derivatives of ethinyl estradiol and nortestosterone.
