Environmental Chemicals Are Feminizing Boys

pickens writes "Denmark has unveiled official research showing that two-year-old children are at risk from a bewildering array of gender-bending chemicals in such everyday items as waterproof clothes, rubber boots, bed linen, food, sunscreen lotion, and moisturizing cream. A picture is emerging of ubiquitous chemical contamination driving down sperm counts and feminizing male children all over the developed world. Research at Rotterdam's Erasmus University found that boys whose mothers were exposed to PCBs and dioxins were more likely to play with dolls and tea sets and dress up in female clothes. 'The amounts that two-year-olds absorb from the [preservatives] parabens propylparaben and butylparaben can constitute a risk for oestrogen-like disruptions of the endocrine system,' says the report. The contamination may also offer a clue to a mysterious shift in the sex of babies. Normally 106 boys are born for every 100 girls: it is thought to be nature's way of making up for the fact that men were more likely to be killed hunting or in conflict. But the proportion of females is rising. 'Both the public and wildlife are inadequately protected from harm, as regulation is based on looking at exposure to each substance in isolation, and yet it is now proven beyond doubt that hormone disrupting chemicals can act together to cause effects even when each by itself would not,' says Gwynne Lyons, director of Chem Trust."

    So you're saying humans evolved to play with things that didn't exist when we became humans?

    No, toys evolved to fit gender preferences.

    The toy preference is also observed in apes: female chimps prefer dolls, male chimps prefer cars.

    In short, yes.

    Denmark has _no_ rednecks/chavs/illiterate underclass. Quite frankly it's amazing, and is mostly a result of huge investment in education after the second world war.

    It's a perfectly ridiculous thought. Many of the listed 'masculine' qualities aren't masculine, and almost all of the 'feminine' qualities aren't feminine either. And this idea some people (seemingly including the OP) have that the world would be all sunshine and happiness and everyone would shit rainbows if we put women in charge is just delusional.

    These reports come out every few years (re: DDT, et al.), and while they're not strictly incorrect, they tend to look at a very incomplete picture of what is going on. To be perfectly blunt, there's sexism going on in that these reports focus on just the environmental impact of chemicals on boys, and don't consider the larger picture of chemical impact on children in general.

    Anyhow, if you take a look at the steroidgenesis diagram, you'll notice that testosterone is a precursor of oestrogen by way of aromatase:

    http://en.wikipedia.org/wiki/File:Steroidogenesis.svg
    http://en.wikipedia.org/wiki/Aromatase

    Now, for those people who remember their organic chemistry and stoichiometry, rates of conversion reactions are increased with catalysts, and decreased with modulators. So, while aromatase will increase the rate at which testosterone converts into estrogen, an aromatase inhibitor will decrease conversion of testosterone.

    And it turns out that Aromatase Inhibitors are naturally occurring:

    So, simply put... what about the environmental chemicals that are masculinizing girls? Is it really just a matter of plastics feminizing boys? Or does it go both ways? Is it a matter of environmental toxicity in general?

    Lastly, I'd also bring up the question whether feminization of boys is primarily caused by environmental chemicals, or if it's driven be completely different factors, such as 1) a cultural response to civil rights access for women, 2) decreased opportunities for war caused by nuclear detante, or 3) need for peaceful co-existance due to worldwide population increases a

    Also, child rearing isn't a particularly female position beyond infancy. Girls simply got stuck with it because they gave birth so its their responsibility. And the idea that violence and aggression is a manly thing. Or that it is something we should hope to aspire to is complete BS.

    It's not just that the woman gave birth. One partner has to gather food / earn money / etc. Historically speaking, the man was more capable of doing this job because of his physical makeup. So the other job of caring for children fell to the female. Not to mention that, again historically speaking, the amount of time she was not caring for one infant or another was usually pretty small.

    You could also argue there are other gender differences that make women more effective at caring for children that aren't just the result of socialization. I don't have a link handy, but I recall reading some research about how women (as a group) are better able to discern emotions by looking at the faces of other people. Stuff like that.

    I'm not mentioning these to defend the idea that men should have no part in child-rearing. Not at all. But I think you oversimplify the reasons why this task has traditionally fallen to women.

    Depends on which neck of the woods you live in.

    Living in ultraliberal Massachusetts, a lot of time and energy goes into figuring out how to get the most education out a buck. Recently my local school system implemented "flexible tracking", in which kids are frequently tested and reassigned to different tracks on a subject by subject basis throughout the course of the day. If you tested ahead on a specific math skill you might be grouped with students needing drill on that subject in one period, then grouped with other students doing a challenge project in reading in the next. After the next test, you might be ahead of the average in the next math skill to be covered.

    We were doing education reform years before most of the rest of the country. The promotion of education was written into our constitution by John Adams. As a result, our state rankings in things like literacy, math and science are consistently either first in the country or for practical purposes statistically tied with first. We have a relatively high per capita spending on students, but not anywhere near the highest. We have a relatively low student to teacher ratio, but not anywhere near the lowest. We also have a lot of poor urban school districts with all the problems they bring.

    What we have is a lot of people who *care* about education, who think it's worth doing something about. It's easy to lose track of that, but when I travel to other parts of the country with lousy rankings, what I find is that people would like to bellyache about how bad the schools are, how incompetent the teachers are or how useless the administration is, but don't actually plan to *do* anything about these things. Politicians rail against the schools, and promise to institute "tough" standards (as if "tough" were a substitute for "intelligent"), but they don't have a plan to do anything with the data they get from the testing other than to close as many public schools as they can. Now I'm not against private education or charter schools, but the theme seems consistent. People don't can't be bothered to pay attention to the details. They don't want to be burdened thinking about it.

    If you want an explanation for the "failures of our school system", I'll give it to you: times have changed, and the schools haven't kept up. We aren't competing with a war ravaged Europe and a world full of ignorant, impoverished countries. We're competing with modern Europe; with an India that has a middle class as large as our entire population; with China whose government has consciously played our relationship in a mercantilist zero-sum game, using favorable exchange rates and low wages to achieve economic power over us. Now tell me what we need to do to education to bring back the glory days of the 1950s, and you'll have redefined education reform for this century.

    As for the "hollowing out" of our culture, I don't see it, although when I took my kids to the opera the other night, nobody was dressed in white tie. What we've had is not a "hollowing out" of our culture, but twin processes of democratizing high culture and the growth of commercial, popular culture. People spend a lot more time being entertained then they did in the 1930s or even the 1960s.
