Brief Summary
The investigators are doing this research study to look at the relationship between testosterone (the main sex hormone in men) and insulin (the hormone that controls blood sugar levels) in men with Idiopathic Hypogonadotropic Hypogonadism (IHH). The investigators hypothesize that normalizing testosterone levels in men with IHH enhances insulin sensitivity, reduces visceral fat, increases lean body mass, and improves the lipid profile.
