Is soy bad for you?
Soy has remained a hot topic of debate in the health food industry. This species of legume, which is native to East Asia, is used to make everything from cereal and milk to burgers and baby formula.

When these products are consumed they can be toxic to the nervous system, which in turn can negatively impact fertility. It’s not just women who have to have to be concerned about their soy intake. One study found that men who consumed more than two portions of soy a day had an average of 41 million less sperm per milliliter of semen.

Do monkeys have estrogen?
Again I would like to mention here that both rats and monkeys produce much higher levels of equol (an estrogen like substance which is much stronger than soy isoflavones) in their intestines than humans in general. The equol is produced through fermentation of isoflavones by bacteria which reside in the intestine. It’s hard to compare humans directly with rats or monkeys especially when it comes to estrogenic effects. Studies investigating the effects of phytoestrogens on the fertility of different animal species have been very inconsistent. This indicates that soy has very species specific effects on fertility and highlights the need for more studies on humans before we can draw definitive conclusions.
