If a man is on chronic prednisone, does that decrease his fertility?

It could: Most people on long-term steroids have a significant illness and thus either the disease or the medication could affect fertility. The good thing is that checking a man's fertility potential is one of the easiest parts of the fertility examination and one of the least expensive!

Prednisone fertility: There is no evidence to indicate a negative effect of Prednisone on male fertility. In fact, Prednisone is often used to treat low sperm motility (movement) secondary to sperm antibodies (autoimmune reaction against one's own sperm).
