Normalization of Morning Testosterone Levels in Men With Secondary Hypogonadism

The Purpose of the study is to determine the effects of Androxal on morning testosterone and reproductive status in men with secondary hypogonadism(confirmed morning Testosterone less than 250 ng/dL), compared to changes with placebo, or Testim (topical testosterone). The effects of Testim versus placebo on reproductive status will also be examined. Study subjects must not be currently using a topical testosterone.

This study is a phase IIb, 4 arm study with three month active dosing period. Three of the four treatment groups will be randomized to either Androxal or placebo in a double-blind fashion, and the fourth treatment group will receive open-label Testim. The doses of Androxal in the blinded portion of the study will be 12.5 mg and 25 mg, in capsule form.
