Hi ladies,

Zara, (no offense please) the op's question wasn't based in ignorance (however passive aggressive you state it to be). Estrogen metabolism takes multiple pathways, gene activation (or lack thereof) plays a bigger role in all ethnicities. Improving DNA synthesis & estrogen metabolism rather than taking mass quantities of PM (or other phytoestrogens) appears to be the suitable option (in my opinion fwiw). 1-2 cup size differences in global breast sizes seem insignificant to me, so I'll mention what my scientist friend from Italy pointed out about the differences in equol (a non-steroidal estrogen) metabolism, which highlights the differences between some asian vs. western populations.

yep, maybe in men the estrogenic activity of soy is more effective than in women, but also it depends on individual genetics. You'll see in the link below, a very good article that summarize a lot of papers about phytoestrogens. After reading that, you can just say: yes, it could nbe helpful as it could be harmful... and maybe it's wise stay in the middle, not exceed:

an extract of the article: (here it is something in english about equol and its conversion)

Equol has been shown to have the strongest binding affinities and estrogenic activities (especially for ERβ) among the daidzin metabolites and has been hypothesized to be largely responsible for the estrogen-like activities of soy and its isoflavones. However, there is a great deal of variation among individuals in the metabolism of genistin and daidzin, which appears to be dependent partly on environmental factors, including other components of the diet, and partly on genetic factors.

Only 25% to 35% of the U.S. Caucasian population is capable of converting daidzein to equol, whereas people in high soy consumption areas of Asia have rates closer to 40% to 60%. There is some evidence that Hispanic or Latino women are also more likely to be equol producers. Approximately 80% to 90% of people harbor the bacteria required to produce ODMA. The frequency of equol producers in one study of vegetarians was found to be 59%, similar to the reported frequency in Japanese adults consuming soy, and much higher than for nonvegetarian adults (25%). One Japanese study found that consumption of dairy products was significantly higher in those who did not excrete equol than in those who did.
