Study Summary

The purpose of this study is to determine whether young women with functional hypothalamic amenorrhea (premenopausal HypoE) is associated with risk factors for pre-clinical cardiovascular disease (CVD). For this study, the investigators will measuring vascular function and inflammatory markers on: * young women with functional hypothalamic amenorrhea (\>3 months of no menstrual cycle due to low estrogen) * young women with regular menstrual cycles not on hormone therapy. * recently menopausal women (\<3 years from final menstrual period) not on hormone therapy. Premenopausal HypoE participants (women with functional hypothalamic amenorrhea) will be randomized to use either an estrogen patch or a placebo patch (no active medicine) for 12 weeks, followed by estrogen or placebo patch plus progesterone or placebo pills for 2 additional weeks. The investigators are looking to see if estrogen improves vascular and inflammation.

Primary Outcome

Change in PAT measured as reactive hyperemia index (RHI) from baseline to week 12 on treatment or placebo. Reactive hyperemia index (RHI) is the post-to-pre occlusion PAT signal ratio in the occluded arm, relative to the same ratio in the control arm, corrected for baseline vascular tone of the occluded arm calculated by taking the ratio of the pulse amplitude during the hyperemic phase (after a period of blood flow occlusion) to the baseline pulse amplitude. The values below \<1.67 are abnormal
