To Evaluate Sperm Parameters in Men With Secondary Hypogonadism Previously Treated With Topical Testosterone
A Randomized, Open-Label, Fixed Dose, Active-Control, Multi-Center Phase IIB Study to Evaluate Fertility in Men With Secondary Hypogonadism, Comparing Androxal® to a Topical Testosterone in Men Previously Treated With Topical Testosterone.

The study was designed to determine if Androxal® would affect sperm parameters (count, concentration, volume) in men with secondary hypogonadism who have been previously treated with topical testosterone.

The study was designed to determine if Androxal® would affect sperm parameters (count, concentration, volume) in men with secondary hypogonadism who have been previously treated with topical testosterone. A maximum of twelve subjects per group were randomized to daily treatments of Androxal® or topical testosterone (Testim®) for six months. The protocol was later amended to include a treatment group who received Androxal after a 3 month wash out period.
