I too have become impotent because of the use of prednisone
. When I was put on 40mg a day
for over a month, alternating after ten days
to 40/20, 20/10, etc. the effects were devastating.
Not only did I lose my ability to achieve an erection, but I lost all feeling. The prednisone makes me urinate every hour. Sugar was checked at 87, and it is OK. Then came the cramps.
