How Much Dutasteride Could Make Me Sterile?

I take dutasteride (generic avodart), I think its 0.5mg or 1.0 mg…either way its one pill. Will this potentially cause sterility or would I need a much higher dose?

I doubt that doses of 0.5mg or 1mg would have any certainty with regard to sterility. The information on this complication is presently not very plentiful.
