Parathyroid Hormone for the Prevention of Bone Loss Induced by Estrogen Deficiency

Abstract

Analogues of gonadotropin-releasing hormone (GnRH) are often given to induce hypogonadism in women who have estrogen-dependent disorders such as endometriosis and uterine leiomyomas. Because estrogen deficiency causes bone loss, concern about premature osteoporosis has prevented long-term therapy with GnRH analogues. We conducted a study to determine whether parathyroid hormone could prevent bone loss in women receiving therapy with GnRH analogues.
