Abstract

To examine the effect of estrogens on circulating levels of calcium-regulating hormones, total serum calcium, ionized calcium, inorganic phosphate, immunoreactive parathyroid hormone, calcitonin, 1,25-dihydroxyvitamin D, and estradiol (E 2) levels were assayed on menstrual cycle days 3 and 13 in 12 healthy young women. Despite a 3-fold increase in serum E 2 levels by midcycle, no differences in the other factors were observed. Furthermore, i.v. infusion of calcium (3 mg/kg over a 10 min period) produced similar changes in the serum levels of immunoreactive parathyroid hormone and calcitonin on days 3 and 13 in 8 women. The authors' findings suggest that in normal menstruating women, endogenous increases in E 2 neither directly nor indirectly stimulate 1,25-dihydroxyvitamin D production, nor do they affect circulating levels of the hormones known to influence calcium homeostasis in man.
