For men breast enlargement seems to be a matter of increasing estrogens, increasing the conversion of testosterone to estrogen and minimizing the conversion of testosterone to DHT. Additionally you could increase hormones in general, you would just want to make sure you increase the conversion of the hormones to estrogen, and block conversion to dht.

Ok, now where talking!

AROMATASE BOOSTERS
Foods such as tofu, soybeans, soy protein isolate, sunflower oil, soybean oil, corn oil and alcohol boost aromatase and should be avoided if you are taking aromatase inhibitors advices FoodForBreastCancer.com. Avoid these foods if you are a bodybuilder taking anabolic steroids or if you suffer from gynecomastia. Aromatase converts excess testosterone from steroid use into estrogens.
