Brief Summary

Approximately 4 to 5 million men in the U.S. are testosterone-deficient. Enclomiphene (trans-clomiphene) citrate (Androxal) was evaluated to determine if Androxal increased serum testosterone levels in men with secondary hypogonadism. Subjects were randomly assigned to 1 of 4 treatments groups. Appropriate amounts of medications were dispensed at each visit. Subjects took their medications orally or by rubbing it onto the skin (depending on the treatment assignment) once daily for up to 6 months. Treatment visits occurred at approximately 4-week intervals for Months 1, 2, and 3 and then at 6-week intervals for Months 4, 5, and 6.

5 g applied topically daily. The subject was to return to the clinic every 2 weeks for the first 2 months to monitor serum testosterone levels. If testosterone concentration remained below the normal level, the dose of AndroGel® could have been increased to 10 g and then to 15 g according to the guidance provided in the product package insert.
