Genetic receptors found that seem to impact the way finasteride works on different people
“Long-term adverse symptoms of men who used oral finasteride against androgenic alopecia have been recently described as post-finasteride syndrome (PFS).” These men report that the sexual side effect after taking finasteride seem to hold for them for long periods of time. The frequency of this finding shows that it is not common as most men who develop the negative sexual side effects of finasteride, return to normal after stopping the medication. The following article recently appeared in the Journal of Sexual Medicine and is worth reading. What it suggests is that there may be differences in the genetic make-up of patients who experience PFS as compared to most others.

Does this mean that you do in fact now endorse the view that finasteride can cause side effects in *some* men? Even if this is rare, and most who get side effects do fully recover, this is certainly worth acknowledging outright than slipping into a couple of blog posts after nearly a decade of arguing otherwise.
