a multi-center study in men with acquired hypogonadotropic hypogonadism to compare changes in body composition and metabolic parameters with diet and exercise in conjunction with treatment with 12.5 mg or 25 mg enclomiphene

Conditions: Acquired Hypogonadotropic Hypogonadism; Obesity

Summary: the purpose of this study is to compare the effects of 12 months of treatment with enclomiphene 12.5 mg, 25 mg, or placebo capsules on body composition and metabolic parameters in overweight men with acquired hypogonadotropic hypogonadism \[confirmed morning testosterone (t) ≤300 ng/dl\] following a 6 month diet and 15 month exercise program.

to compare the effects of 12 months of treatment with enclomiphene 12.5 mg, 25 mg, or placebo capsules on body composition and metabolic parameters in overweight men with acquired hypogonadotropic hypogonadism (confirmed morning t≤300 ng/dl) following a 6 month diet and 15 month exercise program. participants must not have been treated with testosterone products in the 6 months prior to the study and must not ever have used testosterone products for a year or longer.
