Abstract
Potential broad clinical uses of GnRH analogs in gynecological applications raise several issues regarding the safety of these peptide hormones in women. These analogs have widespread applicability in a variety of disorders such as leiomyomata uteri, polycystic ovarian disease, prior to laser ablation for dysfunctional uterine bleeding, and infertility [1–10]. Included in these indications is the treatment of endometriosis [2], a ubiquitous disease in reproductive-aged women. GnRH analogs decrease ovarian steroidogenesis through selective hypophysectomy with reduced gonadotropin release; and thus diminish estradiol levels. The GnRH induced hypoestrogenic state raises concerns about effects on bone mass, especially in women with endometriosis, a disease which is associated with decreased bone [11], as well as in the treatment of fibroids in perimenopausal women, who may already have altered bone turnover. This potential side effect of GnRH analog therapy is important, since estrogen appears to be a critical factor in the regulation of bone turnover. Consequently, bone density response during GnRH analog use must be carefully assessed in all women, and particularly in the perimenopausal population.
