Ja vegāniem ir augstāks testosterons, tad viņiem ir arī augstāks sekshormonus saistošais globulīns, kas varētu nozīmēt, ka viss tas ekstra testosterons ir piesaistīts un neizmantojams. Absolūtā testosterona līmenis neko nenozīmē, svarīgi ir cik ir 'brīvais testosterons':

“Mean serum insulin-like growth factor-I was 9% lower in 233 vegan men than in 226 meat-eaters and 237 vegetarians (P = 0.002). Vegans had higher testosterone levels than vegetarians and meat-eaters, but this was offset by higher sex hormone binding globulin, and there were no differences between diet groups in free testosterone, androstanediol glucuronide or luteinizing hormone.“
