Influence of estrogens on calcitonin secretion.

In this study we investigated the calcitonin (CT) pattern both in basal conditions and after calcium infusion before and one month after oophorectomy in 17 premenopausal women. In addition, 13 oophorectomized women were randomly allocated to two groups, one given hormone replacement treatment and the other untreated, and CT response to hypercalcemia was reevaluated one year later. CT response to calcium infusion was significant only before oophorectomy and one year after estrogen-progestogen treatment, whereas there was no response one month after oophorectomy or after one year without hormone replacement therapy. Our data indicate that both estrogen secretion and replacement treatment may be important factors in CT response.
