Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
