McGonigal's Worm

In Short

This story explores the psychological and societal ripples of a world without a future. When every chordate on Earth—from fish to man—suddenly loses the ability to conceive, civilization enters a long, strange twilight. As humanity confronts its inevitable end, it oscillates between nihilistic indulgence, bureaucratic preservation of knowledge, and a frantic, scientific quest for a biological miracle. It is a work of quiet, speculative dread that lingers on the absurdity of human institutions when they are stripped of the necessity to plan for the next generation.

The Story

The crisis begins silently. A worldwide, instantaneous loss of reproductive capability among all chordates goes unnoticed for days, until laboratory disruptions and medical failures reveal the truth. Within a week, the scientific community is reeling, though the public greets the news with skepticism. Once the reality sets in, the world changes. The focus of human existence shifts from growth and legacy to the morbid fascination of the "world sweepstakes," where citizens place enormous bets on which pregnant woman, anywhere on Earth, will be the final mother to give birth.

Years pass. The "last" child is born after a record-breaking pregnancy, and global society begins the slow, melancholic process of closing schools and abandoning the construction of homes meant for future families. International institutes form to study the cause—cosmic rays? A hostile alien influence?—but every lead ends in a blind alley. When a "possibility test" identifies one fertile man and one fertile woman among the billions of survivors, the world breathes a collective sigh of relief, assuming salvation is at hand.

The two individuals, Musha ibn Scmuel and Cecilia Clutt, are brought together, but the attempt to force them into a union of necessity ends in disaster. Musha, upon seeing his intended partner, suffers a breakdown and vanishes into the sea, effectively ending the last natural hope for human reproduction. Humanity retreats into various "last ditch" efforts, including a desperate attempt to educate insects or cephalopods to carry on the torch of civilization.

Attention eventually turns to a strange, resilient creature called McGonigal’s Worm, the only chordate left capable of reproduction. A massive research institute is established to study the worm, staffing it with the world's remaining young women. Georgina Hickle, a cynical worker who finds the worms disgusting, begins to display odd physical symptoms. Her condition, dubbed "Hickle's Disease," spreads to other women in the lab, causing panic among the modern, scientific staff. A disgraced, "old fogy" psychiatrist realizes the truth: the phenomenon is not a disease, but the natural return of life. The cosmic radiation that caused the infertility has simply passed, and the species is, once again, fertile. The story concludes with humanity emerging from its long shadow, though the myth that the worms themselves caused the miracle persists among the superstitious.

How It Unfolds

The silent catastrophe The narrative opens with the sudden, global cessation of fertility, a biological "lifeline" cut without warning. It takes days for scientists to realize that the pattern of failed experiments and sterile animals is not a series of accidents, but a universal event.

The sweepstakes of the end As the truth permeates society, the focus turns to the morbidly competitive betting on the world’s final birth. Governments and international bodies struggle to manage the decline, while the "last child" is born amidst international legal squabbles over the exact duration of gestation.

The failed salvation Researchers identify two fertile humans, but the forced pairing fails spectacularly when the male candidate chooses death over the state-mandated union. This rejection forces the world to confront the reality that humanity cannot be saved through simple administrative coercion.

The worm and the miracle Desperate to find a successor species, scientists focus their attention on McGonigal's Worm, the only fertile chordate remaining. The unexpected symptoms appearing in the laboratory staff, initially treated as a medical mystery, reveal that the period of cosmic interference has finally ended.

The People

Musha ibn Scmuel is an unthrifty, plain man from the fringes of society, acting as an unwilling participant in the world’s attempt to force his fertility. His violent, visceral reaction to his assigned partner suggests a profound, unarticulated rejection of a future managed by cold, state-driven logic.

Cecilia Clutt is a wealthy, snooty, and fiercely independent woman who refuses to be used as a vessel for the state. She views the survival of the species as secondary to the preservation of human dignity, arguing that if humanity must end, it should do so with grace rather than through coercion.

Georgina Hickle serves as the unwitting catalyst for the end of the crisis. Her initial disdain for the worm project highlights the gap between the sterile, desperate planning of the institutes and the irrational, biological reality of life itself.

In Its Own Voice

"The facts are incontrovertible. There has been a loss of the power to conceive in sea squirt, lancelet, hag fish, skate, sea cat, fish, frog, alligator, snake, turtle, seal, porpoise, mouse, bat, bird, hog, horse, monkey, and man."

The Director of the Palingenesia Institute summarizes the exhaustive, grim scope of the crisis.

"The point is not whether sterility could have been caused by cosmic forces. Of course it could have been. It could have been caused in twenty ways. The miracle is that fertility had ever been possible."

Hegner reflects on the precarious nature of existence once the biological shield that protected humanity has seemingly failed.

"If it is our time to disappear, then let us disappear with dignity. What you suggest is without it. It would leave us a little less than human."

Cecilia Clutt rejects the government's attempts to treat her as a mere resource rather than a person.

What It's Really About

At its heart, this is a meditation on the arrogance of human planning in the face of vast, indifferent cosmic forces. The book argues that fertility and life are not merely mechanical processes that can be controlled by institutes or "possibility searchers," but are fragile, miraculous states of being. It questions the meaning of civilization when it is untethered from the future, highlighting how quickly moral and social structures decay when the concept of legacy is removed. The story suggests that humanity’s obsession with controlling its survival often blinds it to the fact that the universe operates on scales and rhythms—like the passing of cosmic radiation—that are beyond human intervention or understanding.

Why Read It Today

Readers who enjoy speculative fiction that prioritizes philosophical inquiry over high-octane action will find much to admire here. The tone is dry, sardonic, and remarkably calm, which makes the underlying horror of a dying world feel all the more unsettling. The prose is clean and precise, favoring intellectual puzzles over emotional melodrama.

However, prospective readers should be prepared for the mid-century sensibilities that permeate the text; the gender dynamics and the portrayal of the "last woman" are very much products of a different era, which may feel jarring or regressive to a modern audience. Furthermore, the plot moves with a detached, observational quality that acts more like a chronicle of historical events than a character-driven drama. What stays with the reader is the image of a world that didn't end with a bang, but with a quiet, polite resignation—and the lingering, ironic realization that humanity survived not through its scientific ingenuity or its "last ditch" institutes, but by simply waiting for the universe to change its mind. It is a cynical, yet oddly hopeful, look at our species' persistence.
