Effects of Soy and other foods on Serum Testosterone Levels: an Analysis

Purpose
The purpose of this report is to provide an introduction to androgens and their biological effects in humans, and an analysis of the current peer-reviewed scientific literature concerning the effects of soy and other foods on serum testosterone levels, with the specific intent to ascertain whether the long-standing myth that soy products lower testosterone levels in men is in any way valid, and if so, to what extent. Furthermore, if there is a scientifically and clinically shown relationship between ingestion of soy products and augmentation in serum testosterone levels, this research will attempt to ascertain whether or not this effect is significant enough to warrant changes in diet. Additionally, this report will examine a few of the other ways to naturally augment testosterone levels by modifying ecological factors such as diet and sleep.
