I need to know the percent of the family care physicians (also called
the primary care physicians)practice that is treating patients with
erectile dysfunction.  I know there are approximately 80,000 primary care
physicians (from one of the other Google Answer's helpful researchers
bobbie7), and now I need to know the percent of these physicians
practice devoted to treating erectile disfunction.  I would guess it
is low....in the 10 - 15%, but I do not know and I need a reference.

As an FYI - bobbie7 did tell me that 10% of Urologists time was devoted
to treating erectile dysfunction.

Thank you for your help!!
