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?
I thought that this link from that page was interesting too...not that I'm trying to support steroids or anything, but still... Effects (none) of androgenic hormones and coronary artery disease http://www.ncbi.nlm.nih.gov/pubmed....sDrugs1 ...being a heart patient, it's nice to know...just in case...
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.
