Michael S. Irwig, MD is an endocrinologist at the Medical Faculty Associates in George Washington University, he is also an Assistant Professor of Medicine in the Division of Endocrinology. Dr. Irwig recently published a study in the Journal of Sexual Medicine that dealt with Post Finasteride Syndrome (PFS), which is a relatively unknown and misunderstood phenomenon. Prior to the publication of Dr. Irwig’s study, this topic for the most part had only been discussed on various online support groups dealing with this issue.
While Dr. Irwig admits that the study has its limitations, he thought it was an important first step in understanding why a small subset of men are unable to tolerate finasteride and suffer with persistent sexual side effects, when a large percentage of men seem to do very well on the drug.
Irwig interviewed 71 men aged 21 to 46 using a diagnostic tool known as the Arizona Sexual Experience Scale (ASEX). While the study might not have been what many in medicine would consider truly scientific, the data collected was certainly compelling.
Spencer Kobren recently took the time to speak with Dr. Irwig about his findings on Post Finasteride Syndrome.
