Ovarian Transposition — Moving the Ovaries Out of the Radiation Field
The ovary is one of the most radiation-sensitive organs in the body. For a premenopausal woman, pelvic radiotherapy for cervical cancer will usually stop the ovaries working permanently — an abrupt menopause in her twenties, thirties or forties, on top of a cancer diagnosis. Ovarian transposition is the operation that tries to prevent that, by lifting the ovaries out of the treatment field and pinning them safely above it. It is a small, usually keyhole procedure, it does not delay radiotherapy, and it is recommended in NCCN and ESMO guidance for exactly this situation. It also has real limits, and this page is as clear about those as about the benefits.
- Hormones are the main prize — avoiding an abrupt surgical-style menopause at a young age
- Usually keyhole, often at the same sitting as other planned pelvic surgery — no separate recovery
- It protects against radiation, not chemotherapy — and it does nothing for the uterus
- Protection is real but not absolute — scattered dose still reaches the ovaries, so some women lose function anyway

What the Operation Actually Does
Radiotherapy for cervical cancer is aimed at the pelvis, and the ovaries sit squarely inside that target area. They are also unusually vulnerable: the doses used to treat cervical cancer are far above what an ovary can survive. Left where they are, they stop working, and the menopause that follows is immediate rather than gradual.
Ovarian transposition, sometimes called oophoropexy, moves them out of the way. Working laparoscopically in most cases, the surgeon separates each ovary from the uterus while keeping its own blood vessels intact, lifts it upwards and outwards, and fixes it high on the side wall of the abdomen, above the pelvic brim and clear of the planned field. Small surgical clips are left to mark exactly where each ovary now sits, so that the radiotherapy planning team can see them on the planning scan and shape the treatment around them. It is a short procedure and it is very often done at the same sitting as surgery that was happening anyway, such as a staging laparoscopy or lymph node assessment.
Nothing about the cancer treatment is compromised to make this possible. The radiation field is designed to treat the disease; transposition simply removes the ovaries from it. Where transposition is being considered, it belongs in the same conversation as egg and embryo freezing before treatment, because the two protect different things and are frequently done together. The wider treatment picture is on the cervical cancer overview.
What It Protects — and What It Does Not
Being precise about this saves a lot of later disappointment. Transposition solves one specific problem well and leaves several others untouched.
Your Own Hormones
The main purpose. Keeping the ovaries producing oestrogen avoids an immediate menopause and everything that comes with it — hot flushes, sleep disruption, vaginal dryness, mood change, and the longer-term effects on bone strength and heart health that matter enormously when menopause arrives decades early.
Egg Supply, Sometimes
Where ovarian function is preserved, eggs are preserved with it. This keeps assisted conception with your own eggs on the table for the future, and eggs can be collected from transposed ovaries through the abdomen rather than the vagina if that is ever needed.
The Uterus
This is the limit that matters most. Pelvic radiation damages the uterus itself — its blood supply and its ability to stretch — so carrying a pregnancy afterwards is generally not possible even when the ovaries are saved. Transposition preserves hormones and eggs, not the ability to be pregnant.
Against Chemotherapy
Cervical cancer radiotherapy is usually given with chemotherapy alongside it, and chemotherapy travels in the bloodstream. Moving the ovaries physically does nothing about that. It reduces the radiation hit; it does not make the ovaries immune to everything.
Against Scattered Dose
Even a well-transposed ovary receives some scattered radiation, and the internal component of cervical cancer treatment adds a little more. That is why a proportion of women lose ovarian function despite a technically perfect operation. Protection is meaningful, not guaranteed.
Before, Never After
Once radiotherapy has been delivered, the damage is done and moving the ovaries achieves nothing. The decision has to be made while the treatment plan is still being drawn up, which is precisely why it needs raising at the first oncology appointment.
Younger Women, Mostly
The younger you are, the more ovarian reserve there is to save and the more years of hormone function are at stake. Suitability also depends on the extent of your disease, on whether the ovaries can safely be spared given your tumour type, and on what other surgery is planned.
When It Is Not Advised
Some tumour types and some patterns of spread make preserving the ovaries inadvisable, and the oncological decision always comes first. Your tumour board weighs that before transposition is offered — it is never a purely surgical or purely personal choice.
Read that list as two separate questions: what happens to your hormones, and what happens to your ability to carry a pregnancy. They have different answers.

How It Fits Into Your Treatment Timetable
The operation itself is the short part. What makes it work is the sequencing — surgeons and radiation oncologists agreeing on where the ovaries need to end up before anybody picks up an instrument.
| Stage | What happens | Why it matters |
|---|---|---|
| At diagnosis | You tell the team your age matters to you and ask about ovarian function | Nothing can be arranged once radiotherapy has started — this is a first-week conversation |
| Tumour board | Surgery, radiation and medical oncology decide whether sparing the ovaries is oncologically safe for your tumour | The cancer decision comes first; transposition is only offered when it does not compromise treatment |
| Planning | The radiation oncologist defines where the treatment field will sit, so the surgeon knows how far the ovaries must travel | Too little movement leaves the ovary in the field; the clips make the new position visible on the planning scan |
| The operation | Usually laparoscopic, often combined with other planned pelvic surgery, done under general anaesthetic | Combining it avoids a second anaesthetic and a second recovery, and avoids delaying treatment |
| Recovery | Keyhole recovery is quick — usually a day or two in hospital, and no delay to the radiotherapy start date | Fertility and hormone preservation should never cost you time on the cancer clock |
| Afterwards | Ovarian function is monitored by symptoms and hormone tests; cysts at the new site are a known finding | If function is lost anyway, hormone replacement is discussed early rather than years later |

The Risks, and the Things Worth Knowing Beforehand
Transposition is a low-risk operation as pelvic surgery goes, particularly when it is added to a procedure that was happening anyway. It is not without risk, and there are a few consequences that surprise women afterwards if nobody mentioned them.
Cysts at the new site
Ovarian cysts developing at the transposed position are the commonest thing that happens afterwards. Most cause no trouble and are simply watched on a scan. A minority cause pain or need draining. They can also be alarming on a routine scan if the person reporting it has not been told your ovaries were moved — which is one good reason to carry that detail in your own records.
Loss of function despite everything
Some women go through the operation and still enter the menopause. Scattered radiation dose, chemotherapy given alongside, and age all contribute. This is not a failure of the surgery or a mistake by anyone; it is the honest limit of what moving an organ a few centimetres can achieve. If it happens, the conversation turns to hormone replacement and bone protection — covered on early menopause after cervical cancer treatment.
Surgical risks and rare complications
The usual risks of a laparoscopic procedure apply: anaesthetic risk, bleeding, infection, injury to nearby structures. Specific to this operation, the blood supply to a moved ovary can occasionally be compromised, and an ovary can shift back downwards over time. Chronic discomfort at the new site is uncommon but reported. Your surgeon will quantify these for your own case.
Egg collection later is done differently
Standard egg retrieval goes through the vagina, and a transposed ovary is no longer reachable that way. If assisted conception is used in future, eggs are collected through the abdominal wall instead. It is entirely doable, but the fertility unit needs to know in advance rather than discovering it on the day.
The sentence to hold on to: transposition is about hormones. If your goal is a future pregnancy that you carry yourself, transposition alone will not deliver it after pelvic radiation, and the conversation you need is a wider one — freezing eggs or embryos beforehand, and what the law permits afterwards. Ask for both conversations in the same appointment, before your radiation start date is fixed.

What is ovarian transposition and when does it need to be done?
It is an operation that moves the ovaries out of the area that pelvic radiotherapy will treat. Each ovary is separated from the uterus with its own blood supply kept intact, lifted upwards and outwards, and fixed above the pelvic brim, clear of the treatment field. Small surgical clips mark the new position so the radiotherapy planning team can see and avoid them. It is usually done laparoscopically, and very often at the same sitting as other planned pelvic surgery. Crucially, it has to happen before radiotherapy begins — once radiation has been delivered, moving the ovaries achieves nothing.
Does moving the ovaries guarantee I will not go into early menopause?
No, and anyone who tells you otherwise is overselling it. Transposition meaningfully reduces the radiation dose the ovaries receive, and many women keep their ovarian function because of it. But scattered radiation still reaches them, the internal component of cervical cancer treatment adds a little more, and chemotherapy given alongside radiotherapy affects the ovaries through the bloodstream regardless of where they sit. Younger women tend to do better, because they start with more ovarian reserve. If function is lost anyway, that is not a surgical failure — and the conversation then turns to hormone replacement and bone protection, which should start early rather than years later.
Can I still carry a pregnancy after ovarian transposition?
Generally not, if you have had pelvic radiotherapy, and this is the single most important thing to be clear about. Transposition protects the ovaries — your hormones and potentially your eggs — but it does nothing for the uterus, and pelvic radiation damages the uterus itself, reducing its blood supply and its ability to stretch. So a woman may keep normal ovarian function and still be unable to carry a pregnancy. Where the uterus cannot carry, stored or retrieved eggs can only lead to a baby through a legally permitted surrogacy arrangement in India. If carrying a pregnancy yourself is your goal, that is a different conversation and it needs to happen before treatment is planned.
What are the risks and side effects of the operation itself?
As pelvic surgery goes it is low risk, especially when added to a procedure that was already planned. The usual laparoscopic risks apply — anaesthetic risk, bleeding, infection, and injury to nearby structures. Specific to this operation, ovarian cysts at the new site are the commonest finding afterwards, and most need nothing more than a scan to keep an eye on them. Less commonly, the blood supply to a moved ovary is compromised, the ovary migrates back downwards over time, or there is persistent discomfort at the new site. Recovery is usually a day or two in hospital, and it should not delay your radiotherapy start date.
Will the ovaries be put back where they were afterwards?
Usually not. Once radiotherapy is complete the ovaries are generally left in their new position, because a second operation carries its own risks for no clear benefit — an ovary works just as well higher up as it does in the pelvis. The practical consequence is worth knowing in advance: if you later need eggs collected for assisted conception, the standard route through the vagina is no longer possible, so collection is done through the abdominal wall instead. Tell any fertility unit, and any radiologist scanning your pelvis, that your ovaries have been transposed — it changes what they expect to see.
