Clinical Trial Summary

This study will learn more about how the body uses energy. Usually, the body uses sugars as energy first and then fats are used when the sugar stores are gone. Some people have trouble using fats as energy. This can lead to feeling tired, difficulty exercising, and storing too much fat where it does not belong (like in the muscle). It is believed that some boys and men with Klinefelter Syndrome may not be able to use fats as energy normally, and that a medication called fenofibrate could help this.
