erectile dysfunction
"My MD first put me on a testosterone gel for lack of desire, difficulty in maintaining and erection, etc. with minimal benefit.  Then, he replaced this with Cialis 5mg taken daily.  WOW!  At 70, I am having sex like 40 again which is 2 or 3 times a week and really good.  I'm not sure if it is all physical or partly that my confidence and expectations have been restored.  "
