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."

    Girls prefer to play with dolls, and boys prefer to play with toy cars, guns etc.. This is genetic, not cultural.

    Social factors could perhaps have a role, but there's no evidence for it, as far as I know.

    There is however a lot of evidence that environmental oestrogens have an effect on development, and much of this evidence is nicely summarised in the linked article.

  3. Transsexualism by BlueParrot · · Score: 5, Informative

    One theory about why transsexualism occurs has been that it is a hormone induced neurological change that occurs early in development. While science is far from concluded on weather this is the case, I can from personal experience state that it is not a fun place to be. If there's even a small chance that environmental toxins is contributing to its prevalence then this is a very serious matter and definitely justifies a careful approach on restricting the use of chemicals that can influence gender development.

    To give a slight idea of how strong an effect these things can have on a persons general wellbeing, a Dutch study found 20% of female to male transsexuals had attempted suicide prior to initiating hormone treatment. In comparison the figures following treatment with androgens were just a few percent. Now try to imagine what the effects might be when you expose an entire population to a diffuse cocktail of chemicals that interfere with gender development and you should start feeling a bit uncomfortable about the situation...

    FTFA:

    Yet gender-benders are largely exempt from new EU regulations controlling hazardous chemicals. Britain, then under Tony Blair's premiership, was largely responsible for this - restricting their inclusion in the first draft of the legislation, and then causing even what was included to be watered down.Confidential documents show that it did so after pressure from George W Bush's administration, which protested that US exports "could be impacted".

    Those are gender roles, taught by parenting. If you stick a child in a room with a bunch of girl and boy toys, without showing them which they should be playing with, they would play with all of them.

    That's the popular ideal, but it's simply not true. Social experiments and have shown that even in isolated communities, even if every attempt is made to treat boys and girls the same (so as not to condition them one way or the other), the boys will prefer playing with traditionally-male toys, and the girls will prefer playing with traditionally-female toys.

    Nature, it seems, is not always politically correct.

  6. Mixed up: Biological Gender vs. Feminization by Anonymous Coward · · Score: 4, Informative

    This article does not make sense.

    Biological gender (dictated by the presence of an Y vs. X chromosome) is irrevocably determined at the moment a spermium merges with an egg, excluding very rare cases of extra chromosomes etc. External pollution by endocrine disruptor chemicals plays no role in this.

    Exhibition of female traits in biological males is a completely different story, and there is increasing evidence that this may be linked to certain classes of chemicals.

    However, I am not aware of any studies which link these chemicals to decreased viability of Y-sperm, which could be a reason for the decline of male births. The number of biological males feminized to a degree that they pass and spend their lifes as females, and is however far too low to account for this change.

      Ah... such a simple world you live in. One baby has a Y, and it's male, and the other has an X, and it's female.

      Actually, it's the SRY (sex determining gene) on the Y chromosome that initiates... I said INITIATES sexual distinction in males. Without this gene, the germ cell line "stripe" turns into ovaries. If there is a mutation in this gene, you will get an XY female with ovaries. If this gene is present and there are no mutations in this gene, then the germ cell line "stripe" becomes testicles.

      The testicles produce androgen. Androgen drives the external development of the genitalia. If there is insufficient androgens, or insufficient response to androgens then the scrotalabial folds become labia, and the clitoris/penis precursor becomes a clitoris. If there are sufficient androgens, and response, the scrotalabial folds fuse into a scrotum, and the clitoris/penis precursor becomes a penis. The development of the external genitalia can also vary anywhere along a continuum between the two.

      Separately, the testicles produce Anti-muellerian hormones, which prevent the development of the muellerian ducts, namely, the upper vagina, cervix, uterus, and fallopian tubes. If there is insufficient AMH, or insufficient response, the fetus will develop such organs regardless of the genetic makeup of the child, regardless of the external appearance of the genitalia. YES, there are MEN with UTERUSES, if they're AMH resistant.

      Now... notice that none of this depends upon estrogen levels. That's because the mother floods the bodies of all children with estrogens. However, it's heavily dependent upon hormones that are produced in the testicles. There a number of chemicals that block androgens, and these result in birth defects, which is why you get in ads for things like Rogaine "pregnant women should never even TOUCH these pills."

      There a hojillion different ways to define "biological sex" and none of them are conclusive, and none of them are guaranteed. There are women with XY, and men with XX (and they were born that way, and assigned their sex by doctors), there are women with high androgen levels (5-alpha-reductase deficiency) and men with low androgen levels, there are women with testicles, and men with ovaries, there are women without uteruses, and men with uteruses. The only thing left to define men from women biologically, is external genitalia... and that can be surgically altered.

      So, seriously... you don't know anything... I hope this short lesson on sexual distinction in humans helps you out.

    That could very well be true. Several years ago I heard stories about how estrogen-like chemicals could theoretically leach out of plastic bottled water containers under certain conditions.

    Not any plastics, but polycarbonate is a polymer of Bisphenol A -- and Bisphenol A was investigated as a synthetic estrogen before it was used in plastics. We've know that it had serious biological effects since the 1930s, but I suppose that was just another inconvenient, profit-reducing fact.

    Polycarbonate is everywhere, not just in water bottles but metal cans (to prevent the metal from contact with food contents),refrigerator shelves, baby bottles, microwave cookware, and eating utensils. And it's used industrially in a wide variety of applications. It's even used to coat children's teeth as an anti-cavity measure.

    Exposure to Bisphenol A has been linked to breast cancer, insulin resistance, miscarriage, obesity, prostate enlargement, early onset of sexual maturation, hyperactivity, and increased aggressiveness, as well as increased risk of heart disease and diabetes.

    The chemical industry, of course, assures use that BPA can never leach from polycarbonate in appreciable amounts. There is, however, a very interesting correlation between who funds the research and what results are found.

    Ok Einstein, explain why male-to-female transsexuals that go on estrogen find they cry more, get reduced sex drive, and increased verbal ability, while the reverse is true for female-to-male transsexuals ( i.e testosterone increases libido, reduces their tendency to cry and shifts abilities from verbal to spatial orientation ).

    There's been loads of studies done on how hormones impact psychological factors ranging from the effects of birth control pills ( they use estrogens and progesterones ) to the impact of hormone replacement therapy for women entering menopause. In order to make a long story short there's is little doubt that hormones influence us in all kinds of ways.

    Seriously, between psychoactive substances like alcohol and caffeine, the impact of nutritional deficiencies such as a lack of iodine, and the impact of hormones like I mentioned above, it is very clear that biological factors have a very strong influence on our psychology. The effects may not correspond with common stereotypes and prejudice, and it certainly does not apply on an individual basis, but to claim it is just a matter of upbringing or social conditioning is demonstratively false regardless of how well it might fit with your preferred political ideology.

    Someone above wondered on the effect environmental oestrogens had on animals. In the Potomoc river (runs by Washington D.C) fish are observed to have transgender traits over and above any natural underlying statistic signal and it has been shown to be result of environmental oestrogens. So it does occur.
