Oral Contraceptives Use by Young Woman Reduces Peak Bone Mass
Abstract
The purpose of the proposed studies was to determine the role that hypoandrogenemia plays in the effects of oral contraceptives (OC) on bone metabolism and peak bone mass (PBM) in young female rats. Intact, adolescent/young adult Sprague-Dawley rats were treated with: (1) placebo, (2) OC therapy, (3) OC supplemented with an androgen (methyltestosterone), or (4) anti-androgen therapy (bicalutamide) to determine the potential role that suppression of androgens plays on bone metabolism, bone architecture, and the attainment of PBM. Our specific aims were to determine: (1) If oral contraceptive steroid (OC) use leads to decreased peak bone mass in young intact female rats. Findings: OC use decreased the peak hone mass of young intact female rats. (2) If the addition of a non-aromatizable androgenic steroid to OCs prevents the detrimental effects of OC use on peak bone mass. Findings: The non-aromatizable androgenic steroid did not prevent the adverse efforts of OCs to the growing skeleton of young rats at the dose used; and (3) If the effects of OC use on peak bone mass are equivalent to the effects caused by anti-androgen use. Findings: The anti-androgen used did not mimic the adverse effect of OCs on the growing skeleton of young rats.
