Beliefs and counseling practices among dermatologists regarding sexual and other adverse effects of finasteride

Despite multiple randomized controlled trials and meta-analyses documenting an increased rate of adverse sexual events in men treated with finasteride for either androgenic alopecia or benign prostatic hypertrophy, 29% of dermatologists thought that this was unlikely and 20% were uncertain. Fewer than a quarter believed that finasteride could cause depression or lower sperm counts.
