Persistent sexual dysfunction and depression in finasteride users for male pattern hair loss: a serious concern or red herring?

The use of finasteride for the treatment of male pattern hair loss has recently been the focus of media and internet attention for potential irreversible sexual dysfunction and severe depression. The purpose of this study was to perform a critical review of the recent studies reporting prolonged sexual dysfunction and depression with the use of finasteride for the treatment of male pattern hair loss. A literature search was performed using PubMed to review the literature pertaining to any potential adverse effects with the use of finasteride and its treatment of male pattern hair loss. The authors conclude that the reports of potential irreversible sexual dysfunction and severe depression do raise concerns about the safety of finasteride; however, these studies are wrought with significant bias. Therefore, larger, randomized, double blind, controlled trials are warranted to further ascertain the true potential risks or confirm long-term safety profile of finasteride use.
