What We Carried With Us: The Hidden Migration of DES (DiEthylStilbestrol).

There is a particular kind of inheritance that does not appear on any manifest.

It is not declared at borders. It is not wrapped in cloth or tucked into hand luggage. It does not pass through customs, and no official ever asks about it.

And yet, it travels.

When Jewish families moved across continents in the twentieth century — from Europe to America, from Britain to Israel — they carried with them the visible markers of continuity: faith, language, memory, food, ritual. These are the things we speak about when we speak about migration. These are the things we celebrate.

But some inheritances arrived unannounced.

I live in London. My life is rooted here. And yet the story I carry is not confined by geography.

I am a daughter of DES — Diethylstilbestrol — a synthetic hormone prescribed to pregnant women from the late 1930s through to the early 1970s. It was given in good faith, widely and confidently, to prevent miscarriage and support pregnancies considered at risk.

For decades, it was regarded as a success.

And then, slowly, something began to surface.

In the early 1970s, clinicians began to identify a rare form of vaginal and cervical cancer — clear cell adenocarcinoma — in young women who would not ordinarily have been at risk. The cases were unusual not only in their rarity, but in the age of the patients.

What connected them was not lifestyle, or environment, but something far earlier.

Their mothers had been prescribed DES during pregnancy.

That realisation marked a turning point. What had been considered a protective intervention was now understood to have caused harm across generations. The daughters of those pregnancies — DES daughters — were found to have increased risks not only of this rare cancer, but of structural changes to the reproductive system, fertility challenges, and complications in pregnancy.

The sons, too, were not untouched.

What made DES particularly unsettling was not only the harm itself, but its timing.

The exposure had taken place in utero — before birth, before memory, before consent.

It was, in every sense, a story that began before the person living it had even arrived.

By the time this knowledge began to circulate more widely within the medical community, it was no longer a distant or abstract concern.

For some, it had already arrived much closer to home.

My father was a gynaecologist.

He was not reading about DES as a historical curiosity or an emerging anomaly in the literature. He was reading it as a clinician trained to recognise patterns, to understand risk, to interpret what lay beneath the surface of a diagnosis.

And, inevitably, he was reading it as a father.

That combination is a complicated one.

Medical knowledge, when it is general, allows for distance. It can be discussed, debated, even set aside at the end of the day. But when it becomes specific — when it attaches itself to someone you love — it changes shape.

It becomes immediate. Personal. Impossible to unread.

I have often thought about what it must have been like to encounter those early findings not as theory, but as implication.

To understand, perhaps before many others did, that something intended to protect had instead introduced a different kind of vulnerability.

And to carry that understanding forward — not into a journal article or a conference discussion, but into the everyday act of raising a child.

From the outside, what people saw was strictness.

A level of care, of caution, that could feel — even to those very close to us — excessive. Protective to the point of constraint.

But what is strictness, when viewed through a different lens?

What if it is not control, but translation?

Not an imposition, but an attempt to manage a risk that cannot be fully removed?

Looking back, I can see that what appeared as rigidity was, in fact, a form of vigilance. A father trying to hold a line around something he could not undo. Trying to create safety in a situation where the original decision had already been made, long before either of us had any say in it.

It is a strange dynamic — to be both the child and, in some sense, the patient. To be loved not only as a daughter, but protected as a case that has already been written into.

That duality shapes a relationship.

It introduces a layer of interpretation: of actions, of boundaries, of intentions.

And it takes time — often many years — to understand what was being carried on both sides.

And then those stories travelled.

Because DES exposure is not bound by geography. It moves with families, across oceans and generations. A woman prescribed DES in London, Dublin, or New York may later see her child’s life unfold elsewhere — perhaps in Tel Aviv, Jerusalem, or Haifa.

The story crosses borders, even if the awareness does not.

Israel is a country built on movement. On return. On the gathering of people from across the world, each bringing their histories, their languages, their inherited narratives.

We are used to thinking of those inheritances in cultural or spiritual terms.

But what of the things we did not know we were carrying?

It has taken time to understand all of this.

Time to separate perception from intention. Time to recognise that what I experienced as strictness was, in many ways, an expression of knowledge — and, perhaps, of care shaped by that knowledge.

And time to find a way to articulate a story that does not sit neatly in any one category.

Because DES is not only a medical issue. It is relational. It is generational. It is, in its own quiet way, part of a much larger conversation about what we inherit and how we live with it.

That is what led me, eventually, to write.

Not as an act of accusation, and not in search of retrospective answers that may never fully come. But as a way of making visible something that so often remains unspoken — both in medicine and in families.

In recent weeks, speaking about the book at launches in Newcastle — a place layered with my own early memories — and in Elstree, I have been struck by how many people recognise elements of the story, even if they have never heard of DES itself.

Not the specifics, perhaps.

But the feeling of something having shaped a life before it properly began.
The experience of relationships that only make sense when seen through a wider lens.
The quiet realisation that what once felt restrictive may, in fact, have been protective.

Those conversations have reinforced something simple, but important.

That stories like this do not sit still.

They move.
They resonate.
They find their way into other lives.

If this story resonates, particularly for those in Israel who may recognise something of their own experience within it, I would be keen to hear from you. DES is a global history, but its effects are often lived in isolation.

My book, A Life Lived Chronically, explores these themes in greater depth and is available on Amazon. More than anything, though, it is part of an ongoing conversation — one that I am still learning from.

Not everything we carry is visible.

But sometimes, by giving it words, we allow it to be understood — not only by others, but by ourselves.
