Certain health foods can potentially cause erectile dysfunction by lowering male hormones or increasing estrogen levels in men. Licorice root consumption has been shown to lower testosterone levels, while soy isoflavones from tofu and soy milk can also decrease testosterone and improve oxidative stress markers. Supplements containing androstenedione can increase estrogen levels in men and the risk of erectile dysfunction.
