What the Body Actually Does, and What It Does Not

There is a claim in wide circulation, in wellness writing and in the marketing of a number of services, and it runs roughly like this: a woman who does not have regular orgasms accumulates something — congestion, stagnation, unreleased energy — and that accumulation produces fibroids, hormonal disturbance, gynaecological disease and eventually a general decline in health and function.

It is worth being direct. There is no good evidence for any of it.

Uterine fibroids are benign tumours that respond to oestrogen and progesterone. Their known risk factors are age, family history, ancestry, body composition, early onset of menstruation and never having given birth. Orgasm frequency is not among them. No mechanism has been proposed by which absent orgasm would produce them, and none of the major clinical guidance on fibroids mentions anything of the kind.

The same goes for the broader version. Sexual abstinence does not create a hormonal deficit that the body then carries. There is no store that fills. A woman who has not had sex in five years is not, by that fact, accumulating a pathology.

This essay exists because the claim is worth examining rather than merely denying — it is very old, it keeps coming back, and understanding why tells you something considerably more useful than the claim itself.

This is not a new wellness invention. It is one of the oldest ideas in Western medicine, and its history is not a happy one.

For something like two millennia, European medicine held that a great many of women’s ailments originated in the uterus and in insufficient sexual activity. The organ was imagined as restless, capable of causing disturbance throughout the body, and sexual deprivation was understood as a cause of illness. The word for the resulting diagnosis is built from the Greek for womb.

That framework had a long career. It was used to explain symptoms nobody could otherwise account for, to convert dissatisfaction and distress into a medical condition located in the reproductive organs, and to justify treatments ranging from the useless to the appalling. It survived into the twentieth century and was finally retired from psychiatric classification within living memory.

The important thing about this history is what the framework was for. It was not a discovery about women’s bodies. It was an explanatory device that allowed physicians to place a woman’s unhappiness in her anatomy, where it could be treated, rather than in her circumstances, where it could not.

The modern version is gentler and better intentioned and has the same shape. Unreleased desire accumulates and makes you ill. It locates the problem in the reproductive system, proposes an intervention, and — this is the part that should make anyone suspicious — the intervention is generally something the person making the claim is selling.

Set the folklore aside, because the real physiology is more interesting and does not need exaggerating.

Sexual arousal is a change in autonomic state. Blood flow to the genital tissue increases, lubrication follows from that vascular change, and the nervous system shifts from its ordinary vigilant setting. Orgasm itself is a neuromuscular event: rhythmic contraction of the pelvic floor musculature, a sympathetic surge, and then a pronounced parasympathetic swing afterwards — which is the physiological reason for the specific quality of the calm that follows.

A neurochemical cascade accompanies it, including oxytocin, prolactin and endogenous opioids. These are real and measurable, and they are also short-acting. They explain what the hour afterwards feels like. They do not constitute a nutrient that a person becomes deficient in.

That distinction is the whole matter. An event with real physiological effects is not the same as a requirement whose absence produces disease. Laughing produces measurable changes too. Nobody claims that insufficient laughter causes tumours.

Several effects are reasonably well established, and they are worth having accurately because the exaggerated version crowds them out.

Sleep. The post-orgasm neurochemistry plausibly assists sleep onset, and people report this consistently. It is a real and modest effect on a real and common problem.

Pain threshold. There is a body of research finding that genital stimulation raises pain threshold measurably. This is among the more robust findings in the area and it is specific — a change in pain perception, not a cure for any condition causing pain.

Acute stress response. The parasympathetic swing afterwards is a genuine physiological downshift, in the same family as other things that produce one.

Pelvic floor. Orgasm involves pelvic floor contraction, and pelvic floor condition matters for continence and for sexual function. This is an area where use and condition are genuinely related, and it is also an area where the useful intervention is targeted exercise and, where indicated, specialist physiotherapy.

Notice the size of these. They are real, modest, mostly short-acting benefits to sleep, comfort and mood. That is a fair description and it is not nothing. It is simply not a disease model.

There is a single area where something close to the folk claim has genuine clinical standing, and it deserves to be stated carefully because it is the part most women are never told.

After menopause, falling oestrogen produces real changes in genital and urinary tissue: thinning, reduced elasticity, reduced natural lubrication, altered tissue environment, and in many women discomfort, pain during sex and urinary symptoms. This is a recognised clinical entity with a name, it is common, it is progressive if unaddressed, and it is substantially treatable.

And here the use-and-condition relationship is real. Regular sexual activity and arousal maintain blood flow to the tissue, and this is associated with better outcomes. Clinical guidance on menopausal genital health does discuss continued sexual activity as one factor among several.

Two cautions attach, and they matter. First, this is about tissue health in a specific hormonal context; it is not a general theory of disease and does not extend backwards to fibroids or to anything else. Second, and more practically: the primary treatments are medical — local oestrogen therapy, moisturisers and lubricants, and in some cases other prescribed options — and they work well. A woman experiencing pain or dryness should see a doctor, not resolve to have more sex. Pain during sex is a symptom, and treating a symptom by doing more of the painful thing is bad advice.

What is genuinely true here is narrower and still worth knowing: a woman who expects to want a sexual life in her sixties and seventies has reason to attend to genital health in her forties and fifties, and the medical route is the effective one.

The usual account assumes a direction — absent desire producing dysfunction — and the evidence points strongly the other way, which is both more accurate and more useful.

Reduced desire and reduced arousal are reliably produced by depression, anxiety, chronic stress, exhaustion, pain, relationship distress, and a long list of medications, of which the widely prescribed antidepressants are the most frequently encountered. Perimenopause changes things. Thyroid disorder changes things. Anaemia, which is not rare in menstruating women, produces the fatigue that makes everything else unavailable.

So a substantial drop in desire is far more often a downstream signal than an upstream cause. It is the body reporting that something else is going on.

This yields the single most practically useful sentence in this essay, and it is not the one anybody in this industry has an incentive to write: a real, sustained change in desire is worth taking to a doctor. Not to a workshop, not to a practitioner, and not to a service. There is a list of ordinary, treatable, frequently missed conditions that present this way, and a woman who spends two years pursuing a spiritual or relational explanation for something a blood test would have identified has been badly served.

The disease model gets this exactly backwards, and the reversal has a cost. It tells a woman her low desire is causing her problems, when her low desire is usually telling her about them.

Here is the argument that should persuade anybody inclined to keep using the health claim on the grounds that it is motivating.

The disease model is strategically bad even setting truth aside, for two reasons.

The first is falsifiability. A claim that absent orgasm causes fibroids can be checked, and it fails. Attaching a real case to a false one means the real case goes down with it. A reader who discovers the fibroid claim is nonsense has every reason to discard everything that arrived alongside it, including the parts that were true.

The second is worse and less obvious. If the reason to attend to your erotic life is that neglect makes you ill, then a woman who is not ill has no reason to attend to it. The overwhelming majority of women with absent or minimal sexual lives are in perfectly ordinary health. Under the disease model, they are fine. The model licenses exactly the neglect it was invented to argue against.

Drop the disease and the case improves immediately, because it stops being contingent on a symptom. The reason to have a sexual life you do not resent is that it is one of the ordinary components of a life, like friendship, like being outdoors, like work you do not hate. Nobody demands that friendship justify itself by preventing tumours.

Which brings us to the part that was right all along, and which has been waiting under all of this.

The desire to be desired is a real human want and does not require medical justification. Neither does wanting to be touched, wanting to feel like a person rather than a function, or wanting to recognise yourself in a mirror as somebody with an interior life rather than a schedule.

These things have a cost when absent, and the cost is not pathology. It is narrower and more specific: a person can gradually stop experiencing herself as a body at all. She becomes something that transports competence between obligations. She stops noticing temperature, hunger, tiredness and pleasure at the resolution she once did, because noticing is not useful and the signals are inconvenient.

That is a real thing and it happens to a great many people, and it is not an illness. It is a habit of attention, learned under conditions that rewarded it, and it can be unlearned under conditions that do not.

And the desire to be desired specifically — not accommodated, not tolerated, but wanted by somebody who could have chosen otherwise — is the most persistently under-served want this Library has documented, in every market, in every country it has looked at. It needs no medical framing. It is simply one of the things human beings want, and a life arranged so that it never happens is a diminished life in the ordinary sense, without anybody having to be sick.

The phrase is not a medical term and does not correspond to any physiological process, so it is worth saying what it can honestly describe, because the thing underneath is real.

What people generally mean is an interruption. A deliberate period in which the body is not being used as an instrument — not carrying, not performing, not producing, not available — and in which sensation is permitted to be the point rather than a distraction from the point.

That is a real experience with real effects on how a person feels, and it does not require any claim about hormones. A day in which nothing is demanded of you changes your state. So does sleep, a long walk, a hot spring, and an afternoon in which somebody pays attention to you without wanting anything. These are ordinary goods and they work for ordinary reasons.

What the phrase should not be permitted to smuggle in is the idea that this is a clinical intervention with clinical effects. It is not, and it does not need to be. “This will make you feel more like yourself for a while” is both true and sufficient. “This will rebalance your hormones” is neither.

On the woman who is functioning well, there is something particular worth saying about that profile.

Competence is a trap with an unusual shape. A woman who is good at managing things accumulates things to manage, and the better she is, the more arrives. Nothing in that process contains a stopping condition, and nothing about it looks like a problem from outside, because the output is excellent.

What tends to go first in that pattern is not health and not performance. It is interiority — the part of her that has preferences unrelated to outcomes. She keeps functioning, and the functioning is real and is not a mask. She is simply operating with one of the systems switched off, and because that system produces nothing measurable, nobody notices, including her.

The characteristic report, when something briefly switches it back on, is disproportionate: an intensity of response that surprises her and that she frequently finds embarrassing. It is not disproportionate. It is proportionate to the length of the interval, and the interval is usually much longer than she had realised.

None of that is a medical event and it does not need to be described as one. It is a person discovering that a part of her life has been unattended, which is an ordinary thing to discover and a reasonable thing to do something about.

This essay is not medical advice and cannot substitute for it. Anyone with pain, bleeding, a mass, urinary symptoms, a sustained change in desire, or any gynaecological concern should see a doctor, and nothing here is a reason to delay that.

The account of fibroid risk factors — age, family history, ancestry, body composition, early menarche, nulliparity — reflects the established clinical picture. The negative claim, that absent orgasm is not a known risk factor and that no mechanism has been proposed, is a statement about the absence of evidence, which is by nature harder to demonstrate than a positive finding. The defensible version is that no recognised clinical guidance identifies such a link and no plausible mechanism has been advanced.

The physiology of the response cycle and its neurochemistry is standard and is summarised here in outline. Individual variation is very large and the description should not be read as a specification of how any particular body ought to work.

The evidence on sleep is largely self-reported and modest. The pain-threshold research is among the more robust findings in this field and is nonetheless a laboratory measure of threshold rather than a claim about clinical pain conditions.

Genitourinary syndrome of menopause is a recognised clinical entity and the relationship between continued sexual activity and tissue outcomes is discussed in menopause guidance. The essay states deliberately that the primary treatments are medical, and that pain during sex is a symptom requiring assessment rather than persistence.

The historical account of the uterine explanation of women’s illness is a compressed summary of a very long and much-studied history, and specialists would add substantial nuance about how the framework varied across periods.

The claim that the disease model is self-defeating is an argument rather than a finding. The essay offers it as reasoning, and a reader is free to weigh it.

And the descriptions of diminished interiority and of the high-functioning pattern are characterisations offered because readers recognise them, not measured psychological findings.

This house sells attention, so it has an obvious incentive to tell you that the absence of attention is making you ill. The preceding several thousand words are the reason it will not.

What is on offer is not a treatment, a correction, a rebalancing or a reset in any clinical sense. Nothing described here addresses fibroids, hormones, depression, perimenopause or anything else with a name. If you have one of those, the person you need has a medical qualification, and this Library is not a substitute for finding them.

What is on offer is narrower and does not pretend otherwise. Language, first — a way to describe what you want that does not require you to be unwell in order to be entitled to it, which is most of what this essay has been doing.

And an evening in which somebody is paying attention, the terms set in advance and by you, where saying what you want is the activity rather than the risk, and where nothing is inferred from your silence.

That will not fix anything, because nothing is broken. It is a few hours of being a person with an interior rather than a set of functions — which was always sufficient reason on its own, and never needed a disease to make it respectable.
