Ok,iam not really sure how wiki works but i think everyone can edit a post or article there,all it takes is an account.That doesn't make PFS more valid or invalid.Irving's reseach is full of holes and inconsistencies,no scientific criteria were used to back up his theories,it was just guys claiming that finasteride caused them side effects but without providing any other detail or taking into account other important factors individually.Having said that,i would not take this study seriously,at least not more than i did before added in wiki.
