Soy Protein Studies

Hmm, they come up blank. My Google consultant didn't help me either, except that he showed me that getfit.com claims test levels are not lowered by soy, and t-nation claims test levels drop because of soy.
 
Aaron_F sounds right. I note that they were only published in December and under the PMID it notes "in process" -- possibly it just isn't loaded to the database yet?
 
Unfortunately, you have to pay to get online access to these letters.  Messina generally appears to be a soy advocate, so he may have been questioning the study conclusions (soy protein reduced testosterone).  I saw the original study myself, but there were others published around the same time coming to opposite conclusions.  The contradictory studies on soy continue to be a source of frustration.

These studies raise a potential issue that has prompted me to keep my soy protein intakes at a lower level.  Still, I have had good results using it in the past, so you have to wonder.
