Key TJ, Roe L, Thorogood M, Moore JW, Clark GM, Wang DY. Testosterone, sex hormone-binding globulin, calculated free testosterone, and oestradiol in male vegans and omnivores. Br J Nutr 1990;64(1):111-9. Cambridge Journals Online - British Journal of Nutrition - Abstract - Testosterone, sex hormone-binding globulin, calculated free testosterone, and oestradiol in male vegans and omnivores
Total testosterone (T), total oestradiol (E2) and sex hormone-binding globulin (SHBG) concentrations were measured in plasma samples from fifty-one male vegans and fifty-seven omnivores of similar age. Free T concentration was estimated by calculation. In comparison with the omnivores, the vegans had 7% higher total T (P = 0.250), 23% higher SHBG (P = 0.001), 3% lower free T (P = 0.580), and 11% higher E2 (P = 0.194). In a subset of eighteen vegans and twenty-two omnivores for whom 4 d diet records were available, there were statistically significant correlations between T and polyunsaturated fatty acids (r 0.37), SHBG and fat (r 0.43 for total fat, 0.46 for saturated fatty acids and 0.33 for polyunsaturated fatty acids), and SHBG and alcohol (r-0.39). It is concluded that a vegan diet causes a substantial increase in SHBG but has little effect on total or free T or on E2.

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.

it said nothing of the sort about e2
The first study reported higher E2 for vegans but it wasn't statistically significant.

ok, I missed that, but I guess the fact that it wasn't significant is what we should emphasize
probably the fact that free T was raised would account for an equal raise in e2 one would think

inflammation from all the grains and other inflammatory foods you have in your food selections. I do not recommend vegan diets, 30-40 years ago be different stories. SHBG increases with lower protein, fats, and higher fiber intake. There are medical studies to support this.

The Association Between Plant-Based Content In Diet And Testosterone Levels
PURPOSE: To evaluate the association between the plant-based content of diet and serum testosterone levels in men from the national health and nutrition examination survey (NHANES) database.
MATERIALS AND METHODS: Data on demographics, diet, and testosterone levels was acquired from the NHANES database. Using the food frequency questionnaire, an overall plant-based diet index (PDI) and a healthful plant-based diet index (hPDI) was developed. A higher score on PDI and hPDI indicates higher consumption of plant foods.
RESULTS: A total of 191 participants were included, average age was 45 (30-60) years and average total testosterone level was 546.7 +/- 254.7 ng/dL. The mean PDI and hPDI were 50.4 +/- 6 and 50.8 +/- 7.2, respectively. On multiple linear regression analysis, BMI and age significantly contribute to testosterone levels (p < 0.05); however, neither of the diet indexes significantly predicted serum testosterone levels (PDI: p = 0.446; and hPDI: p = 0.056).
CONCLUSIONS: In a well characterized national database, the plant-based diet index is unable to predict testosterone levels. Plant-based food content in diet is not associated with serum testosterone levels.
