In the study of "Combined inhibitory effects of soy isoflavones and curcumin on the production of prostate-specific antigen" by Ide H, Tokiwa S, Sakamaki K, Nishio K, Isotani S, Muto S, Hama T, Masuda H, Horie S., posted in US National Library of Medicine National Institutes of Health, researchers found that isoflavones and curcumin could modulate serum PSA levels. Curcumin presumably synergizes with isoflavones to suppress PSA production in prostate cells through the anti-androgen effects.
