    Soy Milk Increases Estrogen Production?

    Can drinking Soy Milk increase the estrogen in a man's body? Does it increase water weight? I try and stay away from as much dairy as I can because of the water retention and "puffy" look; hence the reason I have substituted Skim milk with SILK.

    ANY COMMENTS ARE APPRECIATED!

    No definitely it does not.


    The ties between soy and estrogen are basically BS.

    Soy is an important protein just like the other proteins.

    as I understand it would take such a ridiculous amount of it to increase estrogen it is negligible

    many studies have shown no connection between soy consumption and estrogen levels in men

    things on paper often don't translate into real world effects becuase the human body is a very intricate machine

    Soy protein powder reduces endogenous testosterone by 19%.

    You wouldnt give a shit if you were on cycle though.

    Clinical and biological activity of soy protein powder supplementation in healthy male volunteers.

    Goodin S, Shen F, Shih WJ, Dave N, Kane MP, Medina P, Lambert GH, Aisner J, Gallo M, DiPaola RS.

    Department of Medicine, University of Medicine and Dentistry of New Jersey/Robert Wood Johnson Medical School, New Brunswick, NJ 08***-2681, USA. goodin@umdnj.edu

    PURPOSE: To determine if a commonly used soy protein supplement exhibits biological activity in vivo and in vitro, we evaluated an over-the-counter soy protein powder supplement using blood from healthy male volunteers and in an estrogen receptor in vitro assay. SUBJECTS AND METHODS: We recruited healthy male volunteers 18 years of age or older that were in good health. Treatment consisted of consuming two scoops (56 g) of pure soy protein powder (Puritan's Pride, Oakdale, NY) daily for 28 days. Serum testosterone and luteinizing hormone (LH) levels were collected on days -7, 0, 14, and 28 of therapy, and day 42. A reporter estrogen receptor (ER) assay was used to determine the effect on ER-beta and ER-alpha in vitro. RESULTS: Twelve subjects were enrolled with a mean age of 32.25 years (range 25 to 47). Serum testosterone decreased 19%(+/-22%) during the 4-week use of soy protein powder (P = 0.021) and increased within 2 weeks after we discontinued soy protein powder. Serum LH concentrations decreased during the 4-week use of soy protein powder then increased within 2 weeks after we stopped the soy protein powder, but the changes did not reach statistical significance (P = 0.20). Soy protein powder was found to induce agonist activity to ER-beta using a reporter estrogen receptor assay in yeast. CONCLUSION: Soy protein powder decreases serum testosterone levels in healthy men and acts as an ER-beta agonist; the significance of this biological effect with respect to cancer prevention needs further study.

    Above study is meaningless and it says so right in the abstract (bold). A sample size of 12 will never produce meaningful results.

    We've argued back and forth on this on this board and other boards... I don't think we'll ever come to an agreement.

    For each study that says that soy lowers test, you'll find one that says it has no effect.

    re: the above study, the sample size was too small... and the protein administered wasn't standardized.

    i.e. No mention of the isoflavone/pytoestrogen content per 56gr etc.
