The purpose of this study is to determine the continued effects of Androxal on morning testosterone and reproductive status in men with secondary hypogonadism who have completed protocol ZA-203. Men will be allowed to choose Androxal (enclomiphene citrate) or Testim (topical testosterone) at the beginning of the study. All men on Androxal will start at 12.5 mg and will be allowed to up titrate to 25 mg if an inadequate response is exhibited at the lower dose.
