Soy Infant Formula and Transgenderism: Is there a link?

An estimated 25% of North American babies receive infant formula made from processed soybeans. Parents use soy formula in the belief that is it healthier than formula based on cows' milk. Soy promotional material claims that soy provides complete protein that is less allergenic than cows' milk protein. When soy infant formula first became commercially available, manufacturers even promised that soy formula was "better than breast milk."

Parents have a right to know how these extravagant claims compare to scientific findings related to soy infant formula...

The most serious problem with soy formula is the presence of phytoestrogens or isoflavones. While many claims have been made about the health benefits of these estrogen-like compounds, animal studies indicate that they are powerful endocrine disrupters that alter growth patterns and cause sterility. Toxicologists estimate that an infant exclusively fed soy formula receives the estrogenic equivalent of at least five birth control pills per day. By contrast, almost no phytoestrogens have been detected in dairy-based infant formula or in human milk, even when the mother consumes soy products. A recent study found that babies fed soy-based formula had 13,000 to 22,0000 times more isoflavones in their blood than babies fed milk-based formula. Scientists have known for years that isoflavones in soy products can depress thyroid function, causing autoimmune thyroid disease and even cancer of the thyroid. But what are the effects of soy products on the hormonal development of the infant, both male and female?

Male infants undergo a "testosterone surge" during the first few months of life, when testosterone levels may be as high as those of an adult male. During this period, the infant is programed to express male characteristics after puberty, not only in the development of his sexual organs and other masculine physical traits, but also in setting patterns in the brain characteristic of male behavior. In monkeys, deficiency of male hormones impairs learning and the ability to perform visual discrimination tasks-such as would be required for reading-and retards the development of spatial perception, which is normally more acute in men than in women.

It goes without saying that future patterns of sexual orientation may also be influenced by the early hormonal environment. Pediatricians are noticing greater numbers of boys whose physical maturation is delayed, or does not occur at all, including lack of development of the sexual organs. Learning disabilities, especially in male children, have reached epidemic proportions. Soy infant feeding-which floods the bloodstream with female hormones that could inhibit the effects of male hormones-cannot be ignored as a possible cause for these tragic developments....
