We need to stop xenoestrogen pollution

Endocrine disruptors in the environment are becoming more abundant due to a wide variety of human-related activities over the last few decades. They affect mechanisms by which the body’s endocrine system generates and responds to hormones, by attaching to receptors in similar ways to natural hormones. Minuscule quantities of hormones can have very substantial effects on the body so even very diluted pollutants may have significant effects. A sub-class called xenoestrogens specifically attach to estrogen receptors in the body and by doing so, can generate similar effects to estrogen in both women and men, affecting not just women’s breasts and wombs but also bone growth, blood clotting, immune systems and neurological systems in both men and women. Since the body can’t easily detach them from their receptors, they can sometimes exert a longer-lived effect than estrogen, remaining in the body for long periods and in women may lead to estrogen dominance. They are also alleged to contribute to prostate and testicular cancer, obesity, infertility and diabetes. Most notably, mimicking sex hormones, they also affect puberty and sex and gender-specific development.

Xenoestrogens can arise from breakdown or release of many products in the petrochemical and plastics industries. They may be emitted from furniture, carpets, paints or plastic packaging, especially if that packaging is heated, e.g. in preparing ready-meals. Others come from women taking contraceptive pills if drinking water treatment is not effective enough. Phthalates are a major group of synthetic xenoestrogens – endocrine-disrupting estrogen-mimicking chemicals, along with BPA and PCBs. Phthalates are present in cleaning products, shampoos, cosmetics, fragrances and other personal care products as well as soft, squeezable plastics often used in packaging but some studies have also found them in foodstuffs such as dairy products and imported spices. There have been efforts to outlaw some, but others persist because of lack of easy alternatives and lack of regulation, so most people are exposed to them, in doses linked to their lifestyles. Google ‘phthalates’ or ‘xenoestrogen’ and you’ll find lots of references to alleged negative effects on intelligence, fertility, autism, asthma, diabetes, cardiovascular disease, neurological development and birth defects. It’s the gender and IQ effects I’ll look at in this blog, but obviously the other effects are also important.

‘Gender-bending’ effects have been strongly suspected since 2005, with the first papers on endocrine disrupting chemicals appearing in the early 1990s. Some fish notably change gender when exposed to phthalates while human studies have found significant feminizing effects from prenatal exposure in young boys too (try googling “human phthalates gender” if you want references).  They are also thought likely to be a strong contributor to greatly reducing sperm counts across the male population. This issue is of huge importance because of its effects on people’s lives, but its proper study is often impeded by LGBT activist groups. It is one thing to champion LGBT rights, quite another to defend pollution that may be influencing people’s gender and sexuality. SJWs should not be advocating that human sexuality and in particular the lifelong dependence on medication and surgery required to fill gender-change demands should be arbitrarily imposed on people by chemical industry pollution – such a stance insults the dignity of LGBT people. Any exposure to life-changing chemicals should be deliberate and measured. That also requires that we fully understand the effects of each kind of chemical so they also should not be resisting studies of these effects.

The evidence is there. The numbers of people saying they identify as the opposite gender or are gender fluid has skyrocketed in the years since these chemicals appeared, as has the numbers of men describing themselves as gay or bisexual. That change in self-declared sexuality has been accompanied by visible changes. An AI recently demonstrated better than 90% success at visually identifying gay and bisexual men from photos alone, indicating that it is unlikely to be just a ‘social construct’. Hormone-mimicking chemicals are the most likely candidate for an environmental factor that could account for both increasing male homosexuality and feminizing gender identity.

Gender dysphoria causes real problems for some people – misery, stress, and in those who make a full physical transition, sometimes post-op regrets and sometimes suicide. Many male-to-female transsexuals are unhappy that even after surgery and hormones, they may not look 100% feminine or may require ongoing surgery to maintain a feminine appearance. Change often falls short of their hopes, physically and psychologically. If xenoestrogen pollution is causing severe unhappiness, even if that is only for some of those whose gender has been affected, then we should fix it. Forcing acceptance and equality on others only superficially addresses part of their problems, leaving a great deal of their unhappiness behind.

Not all affected men are sufficiently affected to demand gender change. Some might gladly change if it were possible to change totally and instantly to being a natural woman without the many real-life issues and compromises offered by surgery and hormones, but choose to remain as men and somehow deal with their dysphoria as the lesser of two problems. That impacts on every individual differently. I’ve always kept my own feminine leanings to being cyber-trans (assuming a female identity online or in games) with my only real-world concession being wearing feminine glasses styles. Whether I’m more feminine or less masculine than I might have been doesn’t bother me; I am happy with who I am; but I can identify with transgender forces driving others and sympathize with all the problems that brings them, whatever their choices.

Gender and sexuality are not the only things affected. Xenoestrogens are also implicated in IQ-reducing effects. IQ reduction is worrying for society if it means fewer extremely intelligent people making fewer major breakthroughs, though it is less of a personal issue. Much of the effect is thought to occur while still in the womb, though effects continue through childhood and some even into adulthood. Therefore individuals couldn’t detect an effect of being denied a potentially higher IQ and since there isn’t much of a link between IQ and happiness, you could argue that it doesn’t matter much, but on the other hand, I’d be pretty miffed if I’ve been cheated out of a few IQ points, especially when I struggle so often on the very edge of understanding something. 

Gender and IQ effects on men would have quite different socioeconomic consequences. While feminizing effects might influence spending patterns, or the numbers of men eager to join the military or numbers opposing military activity, IQ effects might mean fewer top male engineers and top male scientists.

It is not only an overall IQ reduction that would be significant. Studies have often claimed that although men and women have the same average IQ, the distribution is different and that more men lie at the extremes, though that is obviously controversial and rapidly becoming a taboo topic. But if men are being psychologically feminized by xenoestrogens, then their IQ distribution might be expected to align more closely with female IQ distributions too, the extremes brought closer to centre.  In that case, male IQ range-compression would further reduce the numbers of top male scientists and engineers on top of any reduction caused by a shift. 

The extremes are very important. As a lifelong engineer, my experience has been that a top engineer might contribute as much as many average ones. If people who might otherwise have been destined to be top scientists and engineers are being prevented from becoming so by the negative effects of pollution, that is not only a personal tragedy (albeit a phantom tragedy, never actually experienced), but also a big loss for society, which develops slower than should have been the case. Even if that society manages to import fine minds from elsewhere, their home country must lose out. This matters less as AI improves, but it still matters.

Looking for further evidence of this effect, one outcome would be that women in affected areas would be expected to account for a higher proportion of top engineers and scientists, and a higher proportion of first class degrees in Math and Physical Sciences, once immigrants are excluded. Tick. (Coming from different places and cultures, first generation immigrants are less likely to have been exposed in the womb to the same pollutants so would not be expected to suffer as much of the same effects. Second generation immigrants would include many born to mothers only recently exposed, so would also be less affected on average. 3rd generation immigrants who have fully integrated would show little difference.)

We’d also expect to see a reducing proportion of tech startups founded by men native to regions affected by xenoestrogens. Tick. In fact, 80% of Silicon Valley startups are by first or second generation immigrants. 

We’d also expect to see relatively fewer patents going to men native to regions affected by xenoestrogens. Erm, no idea.

We’d also expect technology progress to be a little slower and for innovations to arrive later than previously expected based on traditional development rates. Tick. I’m not the only one to think engineers are getting less innovative.

So, there is some evidence for this hypothesis, some hard, some colloquial. Lower inventiveness and scientific breakthrough rate is a problem for both human well-being and the economy. The problems will continue to grow until this pollution is fixed, and will persist until the (two) generations affected have retired. Some further outcomes can easily be predicted:

Unless AI proceeds well enough to make a human IQ drop irrelevant, and it might, then we should expect that having enjoyed centuries of the high inventiveness that made them the rich nations they are today, the West in particular would be set on a path to decline unless it brings in inventive people from elsewhere. To compensate for decreasing inventiveness, even in 3rd generation immigrants (1st and 2nd are largely immune), they would need to attract ongoing immigration to survive in a competitive global environment. So one consequence of this pollution is that it requires increasing immigration to maintain a prosperous economy. As AI increases its effect on making up deficiencies, this effect would drop in importance, but will still have an impact until AI exceeds the applicable intelligence levels of the top male scientists and engineers. By ‘applicable’, I’m recognizing that different aspects of intelligence might be appropriate in inventiveness and insight levels, and a simple IQ measurement might not be sufficient indicator.

Another interesting aspect of AI/gender interaction is that AI is currently being criticised from some directions for having bias, because it uses massive existing datasets for its training. These datasets contain actual data rather than ideological spin, so ‘insights’ are therefore not always politically correct. Nevertheless, they but could be genuinely affected by actual biases in data collection. While there may well be actual biases in such training datasets, it is not easy to determine what they are without having access to a correct dataset to compare with. That introduces a great deal of subjectivity, because ‘correct’ is a very politically sensitive term. There would be no agreement on what the correct rules would be for dataset collection or processing. Pressure groups will always demand favour for their favorite groups and any results that suggest that any group is better or worse than any other will always meet with objections from activists, who will demand changes in the rules until their own notion of ‘equality’ results. If AI is to be trained to be politically correct rather than to reflect the ‘real world’, that will inevitably reduce any correlation between AI’s world models and actual reality, and reduce its effective general intelligence. I’d be very much against sabotaging AI by brainwashing it to conform to current politically correct fashions, but then I don’t control AI companies. PC distortion of AI may result from any pressure group or prejudice – race, gender, sexuality, age, religion, political leaning and so on. Now that the IT industry seems to have already caved in to PC demands, the future for AI will be inevitably sub-optimal.

A combination of feminization, decreasing heterosexuality and fast-reducing sperm counts would result in reducing reproductive rate among xenoestrogen exposed communities, again with 1st and 2nd generation immigrants immune. That correlates well with observations, albeit there are other possible explanations. With increasing immigration, relatively higher reproductive rates among recent immigrants, and reducing reproduction rates among native (3rd generation or more) populations, high ethnic replacement of native populations will occur. Racial mix will become very different very quickly, with groups resident longest being displaced most. Allowing xenoestrogens to remain is therefore a sort of racial suicide, reverse ethnic cleansing. I make no value judgement here on changing racial mix, I’m just predicting it.

With less testosterone and more men resisting military activities, exposed communities will also become more militarily vulnerable and consequently less influential.

Now increasingly acknowledged, this pollution is starting to be tackled. A few of these chemicals have been banned and more are likely to follow. If successful, effects will start to disappear, and new babies will no longer be affected. But even that will  create another problem, with two generations of people with significantly different characteristics from those before and after them. These two generations will have substantially more transgender people, more feminine men, and fewer macho men than those following. Their descendants may have all the usual inter-generational conflicts but with a few others added.

LGBTQ issues are topical and ubiquitous. Certainly we must aim for a society that treats everyone with equality and dignity as far as possible, but we should also aim for one where people’s very nature isn’t dictated by pollution.



Future sex, gender and design

This is a presentation I made for the Eindhoven Design Academy. It is mostly self-explanatory

Pubic fashion and the Internet-of-genitalia

Not for the easily offended, or my parents, who do read my blog sometimes, but hopefully not this one. This is another extract from my forthcoming book on future fashion. No sector is immune to futurology.

The pubic area may not be talked about much in fashion articles, but it is suited to fashion as any other. Pubic hairstyles (including bald) vary from person to person and over time, but they certainly do get fashion consideration. Vajazzling, decorating the female pubic area with stick-on glitter, has also had its limelight as a fashion thing, Beautifying and styling the pubic area is here to stay for as long as casual sex remains common. If an area gets attention, people will want to make it look sexier or more interesting or enticing, so it is just another platform for personal expression, as much as choice of underwear.

Updating stick-on glitter to LEDs or lasers could make a whole light show down there. This could of course tap into data from sensors that pick up on sexual activity and arousal level. That would allow a direct feedback route on performance. Whoever is pleasuring her could see the results echoed in a visual response in local LEDs or flashing glitter or laser beams. That would be fun, but it could use audio too. Since the pubic region is fairly flat and firm, it also presents a potential surface for flat speakers to generate sound effects or music during sex, again linked to arousal sensor feedback. Of course, speakers are another form of vibration device too so they might also take an active role in stimulation.

Hair management already uses lasers to kill hair follicles, but some women regret having their pubic areas completely depilated, and are now having hair implanted back. As hair styles come and go, what is needed is a better trimming and shaving system. I am surprised the shaver industry has not already picked up on this possibility, (if it has I am not aware of it) but a design could be rendered much better if the shaver can access a local positioning system. If a person sticks on a few tiny transmitters, reflectors or transponders in specific places near the trimming zone, the shaver head would know its exact position and orientation and would be able to trim that specific area precisely as dictated by the chosen pattern. Automated precision hair styles would be feasible without taking too much time. Another cheap and easy way of doing this would be to spray a marker pattern through a stencil and have the shaver trim the areas marked.

Naturally, such shaver technology would also be useful for other areas such as the head or chest (for men anyway, I don’t expect female chest hair to be a significant fashion trend any time soon), or to replace waxing anywhere on the body with precision patterns and trims.

Many people are unhappy with their actual genitalia. Re-scuplting, trimming, tightening, or changing size is becoming common. Gender re-assignment surgery is also growing, but gender-change and gender-play fashion needs a whole section for itself, and I’ve written about it before anyway(my most popular post ever in fact) :

Not in the pubic area, but somewhat related  to this topic nonetheless, here is a quick consideration of smart breast implants:

[Smart breast implants

Smart breast implants are one of my best inventions – the only one for which I have ever received a prize. The idea was that if a woman is determined to expand her breasts by putting stuff into them, why not put electronics in? In fact, electronics can be made using silicone, one of the main breast implant materials. It won’t work as fast as silicon-based IT but it will do fine for things like MP3 players (MP4 now of course). A range of smartphone-style functions could be added as well as music playing. For example, navigation could link location and maps to vibrating nipples to indicate left or right. I suggested using nipples as control knobs for my MP3 implants, and that is perfectly feasible. Detectors in the implant could easily detect torsion and interpret the tweaks. Implants would be able to monitor some biological functions more precisely than wristbands. Heartbeat and breathing could be audio recorded far better for example.

Shape changing breast implants

I often cite polymer gel muscles in fashion, because they are so useful. Contracting when a voltage is applied across them, but made of electro-active polymer so they feel organic, they are ideal for many purposes in and on the body for extra strength of for changing shapes or orientation. Breast implants could contain strands of such gel, arranged so that the shape of the implant can be altered. They could be adjusted to change breast shape, improve lift or cleavage, and relaxed when no-one is looking.

Pectoral implants already give some men the appearance of being more muscular and fit. Adding actual strength using polymer gel muscles rather than simple padding would be a lot better.


Shape change materials could also be used in bras of course, allowing control to be varied by an app. A single bra could work for general and sports use for example. Similarly, hydraulic bras could give extra lift or control by inflating tubes with compressed air. Staying with inflation, of course the bra as a whole could be inflated to give the illusion of larger size.

Bras can incorporate energy harvesting for use while running. A suitable material could be plastic capacitors, which make electricity directly as they flex.

Nipple-tapes could be coupled to vibrators for a slightly more immersive sexual experience, and remote controlled for more kinky play.]

Now, back to the pubic area.

Rather along the same lines as smart breast implants, if someone is going to the lengths of having genital surgery and particularly if implants are involved, then electronic implants could be a useful consideration. Some devices use electrical stimulation, applying particular patterns of voltages and currents to create, magnify and sustain arousal. Devices could be implanted to do exactly this. They could be access restricted to the wearer, controlled by a dominant or even networked for remote control, by any chosen individual or group. MEMS or sensors could also be implanted to create vibration or to measure arousal.

Sensors can easily detect moisture levels, skin resistance, blood flow, blood oxygen levels, heart rate, breathing and so on. These together can indicate a great deal about arousal state and that can be fed back into stimulation system to maximise pleasure. Stimulation devices could provide direct stimulation or work along with external devices such as vibrators, controlling their behavior according to location and sensor feedback. Vibrators shouldn’t need control knobs that distract their users, but should automatically adjust their behavior according to the region they are stimulating and the user’s  arousal profile, changing stimulation throughout the session according to programs and recorded routines stored in the cloud. Shared toys could use fingerprint recognition or implanted RFID chips, but I think that would usually be considered to be going too far. 

An important fashion consideration is that visual appearance can mostly be decoupled from function. Electronics can be shrunk to vanishingly small size and fit in the tiniest of sensors or actuators. Genital and pubic electronics can therefore be visually appealing at the same time as providing a full suite of functionality.

Shape change materials such as electro-active polymers can also be implanted. These could also be used to generate vibration by varying applied voltage patterns appropriately. Shape changing implants could be used to vary tightness during penetration, or to make features more appealing during foreplay.

As with the pubic area as a whole, genitals could also incorporate visual feedback using color change, LEDS or even music or other sound effects according to arousal state. Sound is better generated by pubic speakers though as surfaces are more cooperative to engineering.

Clearly, with a number of feedback and bio-sign monitoring sensors, MEMS, speaker systems, illumination, decoration and visual effects systems, the whole pubic and genital region is a potentially large electronics ecosystem, and we will need a whole branch of IoT technology, which could be termed ‘Internet of genitalia’.
