IIRC soybean products (like tofu) are said to contain small amounts compounds with estrogen-like properties. Hence males consuming significant quantities of these products may be affected by higher than normal level of circulating estrogens. I don't know how much tofu ingestion is required to produce a noticeable effect (such as gynecomastia), but I assume it would have to be a major dietary component. In Asian countries, soybean consumption is much higher than typical in the US, so perhaps more likely to be an issue there. Might be worth a literature search on the subject, but I haven't done that, so I don't know if it's been verified.

This is quackery, as shown by this meta-study: "Soybean isoflavone exposure does not have feminizing effects on men" https://www.ncbi.nlm.nih.gov/pubmed/20378106 https://www.ncbi.nlm.nih.gov/pubmed/20378106.

  Mark Messina (the study's author) is a shill for the soy industry. "M.M. regularly consults for companies that manufacture and/or sell soyfoods and/or isoflavone supplements, and he is the executive director of the Soy Nutrition Institute[0], a science-based organization that is funded in part by the soy industry and the United Soybean Board."[1] More people would trust science if more scientists were not whores.
