My erections are not as hard as they used to be and I do not stay hard for
long. I attribute my erection problems to the
Propecia tablet that I take daily. As you know, Propecia is 1 mg. of finasteride. Propecia has been shown to cause side effects such as erectile problems in a small minority of users. Unfortunately, I appear to be in that small minority. Once my erection problems surfaced, I began looking for a solution.
