The latest news is a case study in the journal Nutrition. The subject is a 19-year-old heterosexual man who become vegan, began consuming a lot of soy,  and, soon after, experienced loss of libido and erectile dysfunction.   Prior to adopting veganism, he had an active sex life with no reported problems. Lab assessment revealed low levels of free and total testosterone with increased levels of DHEA.   During the year prior to this workup, the young man's diet had packed a whopping punch of soy isoflavones, averaging 360 mg per day, from soy milk, soy crisps, tofu, soy sauce, soy nuts and edamame.   This level of soy consumption is far above average, yet increasingly common these days as people quit meat and dairy products for soy substitutes.   Prior to becoming vegan, the man had been on a Standard American Diet (SAD).  After discontinuing his vegan diet and eliminating soy foods altogether, he noticed a gradual improvement in  sexual function over the course of a year and his lab tests revealed  gradual normalization of testosterone and DHEA levels.
