Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Diabetes has recently been referred to as "the epidemic of the 21st century". The reason why women with type 1 diabetes have a 2-3 fold greater risk of cardiovascular disease (CVD) compared to men with type 1 diabetes is unknown.The purpose of this study is to investigate whether or not estrogen contributes to vascular dysfunction in premenopausal women with diabetes.
