I'm new here too and was recently diagnosed with 4th stage COPD and put on O2 therapy. I'm 74 and have suffered with COPD my entire life, most of it with out knowing what it was. No Dr. ever mentioned it to me.
After doing my own research and discovering the many associated effects of the disease I'd like to know how many other men with COPD have also experienced chronic ED which has also been a problem for me.
