For decades, the industrialized world has drifted quietly into a crisis without precedent in human history. Birth rates have fallen below replacement levels in nearly every advanced economy, and many middle-income countries are following the same path. Demographers warned about it. Economists fretted. Politicians preferred not to mention it at all.
But now the mask is off: the fertility crisis is real, and the numbers are impossible to ignore.
The numbers tell the story. In 2023, the fertility rate in the European Union stood at 1.46 children per woman. Japan, mired in demographic decline for decades, reported 1.26 in 2022. South Korea has become the global outlier, with a rate of 0.72 in 2023 — the lowest ever recorded. The United States sits somewhat higher, at 1.62 in 2023, but still well below replacement level (i.e. 2.0 live births per woman).
A century ago, the picture was very different. In 1920, the U.S. birth rate was around 3.3 children per woman; Japan’s in 1925 was 5.0; most European nations in 1920 hovered between 2.5 and 4.0. South Korea in 1960 was at 6.0.
Two centuries ago, fertility rates of 5–7 children per woman, on average, were quite common across all agrarian societies. The post-industrial world’s birth rate decline — one might even say ‘collapse — is stark, and has no historical precedent outside of cataclysmic events like war, famine, and plague.
The modern fertility crisis, however, is a different animal. Instead of the aforementioned calamities suppressing population growth, we now confront a mostly voluntary collapse: individuals in wealthy societies are simply choosing to have fewer or no children, despite unprecedented material abundance. Reversing the decline in fertility will be a daunting task. Hence the title of this week’s post: “Breaking the Wheel of Flesh: Reproductive Technology Takes Aim at the Fertility Crisis”.
The Establishment Misses the Boat – Again
The fertility crisis in industrialized societies is real, and political actors have lately begun to take notice.
In one of his more infamous cultural barbs, Vice President J.D. Vance dismissed America’s “childless cat ladies” as symbols of a decadent elite uninterested in reproduction. The sneer was crude, but it captured a deepening anxiety: entire nations seem to be losing not only the ability, but even the desire, to reproduce themselves.
That it took populist parties and populist media to force this recognition is no accident. The mainstream establishment, with its technocratic confidence, assumed that birth rates would eventually correct themselves. They didn’t.
And while some on the political left still prefer to frame declining birth rates as a sign of liberation — fewer children, more autonomy — just look at the New York Times opinion section (Jessica Grose and Michelle Goldberg stand out as notable fertility collapse rhapsodizers) – the blunt arithmetic of population collapse is finally beginning to cut through decades of ideological denial and obfuscation.
The core truth of the fertility crisis is actually quite simple: without replacement-level fertility, societies shrink, age, and weaken, both economically and militarily. Nations that spent centuries building up their populations now face the prospect of running out of people.
The Roots Run Deep
The problem is that low fertility is not the product of a single bad policy or cultural fad. It has deep, tangled roots in the modern way of life. Women’s entry into higher education and the workforce, the availability of contraception, the social expectation of smaller families, the rising costs of housing and childcare, the delay of marriage and parenthood — all of these factors have converged to suppress birth rates.
The great irony is that these changes are largely irreversible, at least on the timescale that matters.
Even if governments wanted to push women out of the workforce and back into the home — and some reactionary thinkers do suggest it — the broader culture has shifted too far into the ‘low fertility zone’ for that to succeed quickly. Norms around family formation are not like interest rates: you cannot simply reset them and expect results next quarter. It will take multiple generations to undo the changes of the past half-century.
Outliers Exist, Particularly in the U.S.
If modern societies are caught in a fertility death spiral, a few outlier communities continue to resist the overall low fertility pattern, mainly out of religious motivations.
The Amish, with an average of 6–7 children per woman, now number about 380,000 in the U.S., or roughly 0.1% of the population. Conservative Mennonite groups still average fertility rates above 4.0. Orthodox Jews make up about 9% of the U.S. Jewish population, with fertility averaging 3–4 children per woman. Certain traditionalist Catholic enclaves — Latin Mass parishes, Opus Dei communities — likewise sustain family sizes of three to five children.
Collectively, these conservative “dissenter communities”, which Greymantle has touched on in prior blog posts, may amount to less than 1% of the American population, but demographically they punch well above their weight.
Their fertility rates are reminders of what once was normal. But dissenter communities remain small minorities, demographically impressive within their own ranks yet insufficient to alter national birth rate trajectories. In the great sweep of population arithmetic, a few enclaves of high fertility simply cannot offset the collapse elsewhere.
Fear and Arithmetic
What has made the issue suddenly urgent is not simply that fertility is low, but that the political consequences of demographic decline have become visible.
In the United States and across much of Europe, European whites are on track to become minorities. This is no longer the speculative talk of fringe circles; it is a reality that census projections openly acknowledge. The anxiety this produces explains much of the energy behind populist politics, and it is only going to intensify.
And here is the uncomfortable truth: the timeline is too tight for cultural change to bail anyone out. Even if a wave of social conservatism swept the West tomorrow, persuading young couples to marry earlier and have more children, the impact would not be felt in the population numbers for decades. Meanwhile, existing demographic momentum is already pushing societies toward aging and decline.
In other words, the arithmetic is working faster than conservative cultural changes can possibly work in the opposite direction. A sudden upsurge in women who embrace the ‘trad-wife’ role – maybe a few tens of thousands here and there, will not be nearly enough to reverse the decline. Fertility crisis solutions will have to embrace a broad tool kit.
That is why Greymantle believes the conversation around societal fertility will soon move – decisively – into the realm of reproductive technology.
It is not that cultural or religious revivals will disappear. Rather, they will be overshadowed by the more immediate, scalable solutions offered by assisted reproduction. IVF, egg freezing, in vitro gametogenesis, even artificial wombs — technologies once seen as boutique options for the infertile are about to be reimagined as instruments of national survival.
And not only for conservatives. The ‘fertility wars’ will not remain one-sided. Liberals, too, will resist being “outbred” by traditionalists, especially if they believe demographic shifts are pushing national politics farther and father to the right. When fertility becomes a political battleground, both sides will look to reproductive technology to level the playing field.
That, in the end, is the pivot: the recognition that the “wheel of flesh” — the natural limits of human reproduction — is breaking. For most of history, men and women lived within the narrow constraints of biology. In the coming decades, those constraints will be challenged, bent, and in some cases discarded altogether.
The question is not whether societies will embrace these technologies, but how far they will go — and how fast.
Breaking the Wheel of Flesh
The post-industrial world has been turning to reproductive technology since the late 1970s, even since the first ‘test tube baby’ was born in 1978. What began as niche medicine for the infertile — IVF, egg freezing, surrogacy — has evolved into a billion-dollar global industry. In the decades ahead, these tools will be scaled up, normalized, and pressed into service as instruments of demographic survival.
To understand why, it is worth returning to the basic arithmetic of reproduction.
For all of human history, the bottleneck in fertility has not been determined by men, but by women’s bodies. Men can father children well into old age – and frequently have throughout history, and often with women a generation or two (or three!) younger than them.
Women, by contrast, face a brutally narrow reproductive window. Female fertility declines sharply after 35, and natural conception becomes vanishingly rare after 42. That fact, more than the recurring pressures of war, famine, or disease, has been the wheel upon which the future of every human community has precariously turned.
The wheel of flesh is, above all, the female fertility clock. That is the wheel our age is preparing to break — decisively and forever.
The First Wave: IVF
In vitro fertilization or IVF, perfected in the late twentieth century, was the first breach in nature’s monopoly. It allowed women to conceive when biology had seemingly failed.
For some, free or low-cost IVF on a mass scale might seem like a ready solution to the fertility crisis. Yet IVF has never been about increasing the number of children so much as ensuring at least one. In the 1990s and early 2000s, clinics often transferred multiple embryos, leading to twins and triplets. Today, the practice is actively discouraged.
The American Society for Reproductive Medicine now recommends elective single embryo transfer, warning that “multiple gestation is associated with increased maternal and neonatal risks.” For IVF to become a demographic tool — producing large families rather than single miracle babies — it would require heavy social pressure on IVF practitioners to roll back medical guidelines. No such movement is in sight.
IVF has a second weakness: it is still tethered to biology’s timetable: if a woman’s eggs have already deteriorated with age, then IVF merely amplifies the futility. That is why most women over age forty rely on donor eggs when they pursue IVF, not their own. Future IVF innovations may help solve this problem, but IVF by itself won’t be enough.
IVG: A New Frontier
A more radical possibility is in vitro gametogenesis (IVG), the creation of sperm and egg cells from induced pluripotent stem cells. In 2012, Dr. Mitinori Saitou at Kyoto University succeeded in producing functional eggs from mouse skin cells using induced pluripotent stem technology. “The ultimate goal is to apply this technology to humans,” Saitou said, “but that remains a distant future.”
In principle, IVG could make egg supply limitless, allowing women (or same-sex couples) to generate viable gametes at any age. In practice, IVG is still in the laboratory, demonstrated in mice but not yet in humans.
IVG’s promise is truly radical, but its implementation will be fraught with ethical and political battles, not least because it implies the biotechnological manufacturing millions of new embryos, many of which will be discarded without ever having a shot at being implanted in an adult human female.
In the United States, Dr. Eli Adashi of Brown University has described IVG as “the most profound advance in reproductive technology since IVF” — a revolution in reproductive autonomy. Yet he is quick to add that it “opens the door to profound ethical challenges,” including designer genetics, solo parenthood, and the commodification of human life itself.
Artificial Wombs: The “Brave New World” Phase
Another frontier is ectogenesis — gestation outside the human body. Research has already sustained lamb fetuses in artificial wombs for weeks. The technology is moving steadily toward viability for extremely premature human infants, and in time it may be capable of sustaining full pregnancies. For feminists, the appeal is obvious: liberation from the burdens of pregnancy itself. For governments staring down demographic decline, the appeal is even clearer: scalable gestation unconstrained by the risks and limits of human biology.
At the Children’s Hospital of Philadelphia, Dr. Alan Flake has pioneered the EXTEND system (Extra-uterine Environment for Neonatal Development), a fluid-filled biobag connected to an artificial placenta. In 2017, his team kept extremely premature lambs alive and developing for weeks.
“Our system is not designed to replace the womb,” Dr. Flake explained at the time, “but to extend normal development in a physiologic way.” The promise is enormous for neonatal medicine, but also limited: EXTEND is not full ex utero gestation, and as Flake warns, “We are still far away from clinical trials” in humans.
In Japan, Katsuhiko Hayashi of Kyushu University has taken a complementary interest, bridging his work in gametogenesis with the prospects of artificial gestation. “The artificial womb is not a dream,” he has said, “but a long journey. We must proceed carefully, step by step.” Even its advocates concede that artificial wombs are at least two decades away from human use. But two decades isn’t a long time. Within a generation, ectogenesis will be here in force, and an tempting option for millions of infertile couples and singles.
But ectogenesis carries with it the unsettling imagery of Huxley’s Brave New World — assembly-line reproduction, the end of pregnancy as a defining feature of human life, children born not of intimacy but of industrial process. Call it ‘family planning tech’. What was once fringe may soon be viewed as essential.
Images of assembly-line reproduction conjure up the early George Lucas film, ‘THX 1138’ with its mass-produced clone society living below ground in bomb shelter-like hives to wait out environmental catastrophe above, or even the soldier-clone manufacturing facility in the much later George Lucas motion picture, ‘Episode II: Attack of the Clones’ – a part of the popular ‘Star Wars’ film series.
Such images are unsettling. They speak of reproduction without intimacy and infants without parents – only industrial scientists. For religious and ethical traditionalists, this would be human reproduction in its starkest form: life reduced to laboratory surplus.
Ectogenesis matched with assembly line mass production of infant humans may well be part of a phase that post-industrial societies will pass through over the next century — but it is unlikely to be the final destination.
The Holy Grail: Ovarian Rejuvenation and Production of New Eggs
Another track aims not to liberate reproduction from the body, but to extend the body’s natural reproductive window. If IVF was the breach and IVG is now the radical experiment, then ovarian rejuvenation is the Holy Grail.
The key bottleneck has always been women’s declining fertility after 35. Break that wheel, and the fertility crisis itself begins to look soluble.
Imagine if women could produce new eggs continuously, as men produce sperm, well into their sixties and seventies – or even later in life. Suddenly, the sharp divide between male and female fertility would be erased. Women could delay childbirth without the looming fear of age-related infertility.
Couples could return to conceiving children through sex rather than laboratory intervention. Reproduction would remain human, even intimate, while no longer shackled to biology’s cruel and inexorable timetable.
It is this prospect that makes ovarian rejuvenation uniquely powerful. Unlike IVG or artificial wombs, ovarian rejuvenation would not industrialize human reproduction. It would simply bring to women something men have always had – an extended period of reproductive viability.
Dr. Jonathan Tilly at Northeastern University made waves in 2004 with his controversial claim that ovaries may contain stem cells capable of generating new eggs. More recently, Dr. Zaher Merhi, a fertility specialist in New York, has experimented with injecting platelet-rich plasma into the ovaries. “It’s too early to say whether this truly reverses ovarian aging,” Merhi says, “but the preliminary data is promising.”
Biotech startups have taken notice. Firms like Gameto and Oviva Therapeutics are working to delay menopause, framing it not only as a fertility issue but as a “reproductive moonshot” for women’s health and the longevity of their reproductive phase. If successful, their work would redefine the timeline of human fertility.
In doing so, it could carry broad cultural appeal. Liberals will embrace it as reproductive equality, the end of the biological asymmetry between sexes. Conservatives will prefer it because it avoids the mass embryo wastage of industrial IVF and IVG. Both sides will see in it a path out of demographic collapse without surrendering reproduction entirely to machines.
The Fertility Wars Are Here
Make no mistake: the coming decades will see fertility wars every bit as heated as the culture wars of the past several decades. Conservatives already fear being outbred, and liberals will not sit idly by if they believe demographics are tilting politics to the right. Both sides will grasp at technology to level the playing field.
In the short term, this will mean an explosion of IVF, egg freezing, donor gametes, and surrogacy. In the medium term, it may mean experimental ventures into IVG and artificial wombs. But the long-term resolution — the true breaking of the wheel of flesh — will lie in technologies that make women’s fertility continuous, sustainable, and equal to men’s.
That is the pivot now before us: whether the future of reproduction will be assembly-line and industrial, or whether ovarian rejuvenation will restore something closer to the sexual and emotional intimacy of the past, but with a greatly extended individual timeline.
The Female Body Is the Bottleneck
If the fertility crisis is a machinery of interlocking wheels, then the wheel that most resists turning is the biological constraint of women’s fertility. For most of human history, this narrow window defined the pace of population growth. Men could, in principle, father children late into life, but women faced the hard deadline of their mid-30s, after which fertility dropped steeply, and by their early 40s, pregnancy became unlikely. This asymmetry was the bottleneck through which every civilization had to pass.
The choice of many post-modern people to delay active reproduction (as opposed to recreational sex) intersects fatally with the female biological clock. A woman who delays children until her late 30s is not simply waiting — she is closing the door on the possibility of multiple births and shortening her generational contribution to human continuity. That brutal arithmetic has always been there, but modern lifestyles and values have made it the decisive factor.
Conclusion: Breaking the Bottleneck Will Necessitate Radical Choices
This raises two unsettling implications.
First, no amount of subsidized childcare, tax incentives, or family-friendly policy can undo the biological fact that human reproduction requires women to act within a shrinking window. States can bribe parents, but they cannot extend fertility.
Second, breaking this bottleneck — if it is to be broken — will require interventions far more radical than the policy imagination currently allows. We are speaking here not about cultural nudges, but about biotechnology: extending women’s fertility beyond menopause, perfecting artificial wombs, or decoupling reproduction from the female body altogether.
For some, such ideas inspire hope. For others, they look like a nightmare – a dystopia – a world wherein the human family is coldly and clinically redesigned in the laboratory.
Demographic fissures are reflected in politics. While Vance’s “childless cat ladies” jibe has become shorthand for right-wing anxiety about low fertility, U.S. conservatives have also embraced “restorative reproductive medicine” — a fringe alternative to IVF that emphasizes “natural” methods of fertility enhancement. It offers little scientific promise, but politically it serves as a pro-natalist stance that sidesteps the moral controversies surrounding assisted reproduction.
But whichever way one leans, the logic is inescapable: if the fertility crisis is the decisive problem of the twenty-first century, and if women’s biological limits are its deepest root, then technology will either be used to shatter that limit — or civilization will contract within it.
This is the frontier that no government wants to name aloud. And yet, without confronting it, the talk of “solving” the fertility crisis remains a polite fiction.
Until next time, we remain –
