Young vs Old — Who Gets More Finasteride Side Effects?

Hi Dr. Rassman,
In your extensive experience, have you noticed if younger men have had more side effects from finasteride than older men? Thanks.

I don’t know the answer to this question. I would expect that the young man with a typical initial high testosterone level would have less side effects (of sexual nature) than older men who are more complex with erectile dysfunction (ED) problems that come with age.
