Brief Summary:
This is a randomized, multicenter, placebo-controlled study to evaluate the effects of Seasonale, an extended-regimen oral contraceptive, on bone mineral density in adolescent females who have had their menstrual period but now have secondary amenorrhea and also have osteopenia. The duration of the study for each patient will be approximately two years.
