Is Soy Milk Harmful to Men?

It is known that soy contains a plant type of estrogen (phytoestrogen...which has the chemical name isoflavin), but is it powerful enough to change a man's reproductive make-up?

NO

A study was conducted that involved giving men 40mg of soy isovlavins for 2 consecutive months. There was no change in their level of serum sex hormones or testicle volume. Soy does not effeminize men. Testosterone levels change with the consumption of given foods (meat-eaters have a higher amount of testosterone than vegans/vegetarians). Meat-eaters are also more prone to having higher cholesterol than vegans/vegetarians. Vegetarians and vegans are within the normal range of testosterone levels and using an unhealthy standard is not the way to measure testosterone levels.

Soy milk has also been found to reduce some of the estrogen producing hormones in women, which fights against breast cancer!

So all in all, it is safe to consume soy for both men and women.
