There will be 180 male subjects in this study. The study is composed of a Screening Period of up to 30 days during which inclusion / exclusion criteria will be reviewed, screening laboratory results will be obtained and medication washouts will be done as required. Subjects will complete the sexual function questionnaire and depression scale. A one day Baseline Period (Day 0), during which baseline assessments of acne lesion counts, physical examination and Investigator's Global Assessment Scale will be done. The Baseline Period will be followed by a 12-week randomized double-blind Treatment Period, in which subjects will be randomized into Finasteride 23.5 mg group, 33.5 mg group, or placebo group. During the Treatment Period, subjects will visit the study site Day 14, Day 28, and Day 56 for acne lesion counts and review of diaries, concomitant medications and adverse events. On Day 84 subjects will return to clinic for acne lesion counts and review of diaries, concomitant medications, adverse events and remaining study drug will be counted and collected.
