I Was Told I Have CHE And COPD In 2003.

I was told I have CHE and COPD in 2003. I have been taking my meds for 15 years. Over time however, I've noticed the my penis has been shrinking. I'm sure it's my meds. I'm 62 years. I am wondering if taking testosterone supplements would help with my erectile dysfunction or would it be unwise considering my other health issues?
