Endometriosis & Fertility: Naturopathic Support for Conception

The Severity of Your Endometriosis Doesn’t Always Predict Your Fertility

One of the most confusing things about endometriosis and fertility is that the amount of disease found doesn’t always match the difficulty a woman has getting pregnant.

You can have extensive endometriosis and conceive naturally. You can also be told your endometriosis is “minimal” or “mild” and still struggle to conceive.

Part of the confusion comes from the way endometriosis is staged. The commonly used surgical staging system describes things such as the location and extent of lesions, adhesions and ovarian involvement. It wasn’t designed to predict whether an individual woman will become pregnant.

So being told you have Stage I endometriosis doesn’t automatically mean a small fertility impact, just as Stage IV doesn’t mean natural conception is impossible.

What often matters more is what the endometriosis is affecting.

Disease involving an ovary may raise very different fertility considerations from disease affecting the relationship between the ovary and fallopian tube. Deep endometriosis elsewhere in the pelvis may create another picture again.

This is why the type and location of endometriosis can sometimes tell us more about the fertility questions we need to ask than the stage alone.

How Different Types of Endometriosis Can Affect Fertility

What that looks like in practice depends on where the endometriosis is – and what that particular area of disease may be affecting.

Superficial Endometriosis

If you’ve been told your endometriosis is superficial or “mild”, you may have also been reassured that it shouldn’t have much impact on your fertility.

And sometimes it won’t.

But when you’re still not conceiving despite apparently reassuring fertility investigations, “it’s only mild” doesn’t really explain why.

Superficial endometriosis may not have changed the position of your ovaries or fallopian tubes, but that doesn’t necessarily mean the reproductive environment around them is unchanged. The inflammatory and immune changes associated with endometriosis may still influence some of the processes involved in fertilisation and early reproduction.

So a small amount of visible disease doesn’t automatically equal a small effect on fertility – or prove that endometriosis is the reason you’re struggling. It tells us not to dismiss it simply because the disease looks mild.

Ovarian Endometriosis and Endometriomas

If you have an endometrioma – an ovarian cyst containing old blood, often called a “chocolate cyst” – you can find yourself facing a particularly difficult fertility decision.

You want to protect your eggs, so removing something that could be affecting the ovary can seem like the logical thing to do.

But it isn’t always that simple.

Endometriomas are associated with lower ovarian reserve and fewer eggs retrieved during IVF. The inflammatory and oxidative environment around an endometrioma may also affect the follicles developing nearby and potentially the competence or quality of the eggs developing within them, although the evidence around egg quality itself is mixed.

The problem is that removing the endometrioma can affect the same ovarian reserve you’re trying to protect.

During surgery, healthy ovarian tissue can inadvertently be removed or damaged alongside the cyst. This becomes particularly important if you already have a lower ovarian reserve, both ovaries are affected or you’ve previously had ovarian surgery.

So the decision becomes less about “Should I get rid of the endometrioma before trying to conceive?” and more about:

What could I gain by removing it – and what might I lose by operating on this ovary?

Your age, ovarian reserve, whether one or both ovaries are affected, previous surgery, symptoms and whether you’re trying naturally or moving towards IVF can all change that answer. For some women, surgery may make sense. For others, preserving ovarian tissue or considering egg or embryo retrieval before further ovarian surgery may be more important.

There isn’t one endometrioma rule that works for every woman. The priority is protecting the fertility options that matter in your particular situation.

Deep Endometriosis and Adhesions

If you have deep endometriosis, you may assume that a more severe-sounding diagnosis automatically means a more severe fertility problem.

Again, it isn’t necessarily that straightforward.

What can matter is whether the disease has changed the way the reproductive organs sit and move within your pelvis.

Endometriosis can cause adhesions – bands of scar-like tissue that make organs stick to each other rather than moving freely. An ovary may become stuck behind the uterus, for example, or the fallopian tube may be pulled away from its normal relationship with the ovary.

This matters when you’re trying to conceive naturally because releasing an egg isn’t the end of the story. The fallopian tube still needs to be able to collect that egg after ovulation so egg and sperm have the opportunity to meet.

That creates an important distinction if you’ve been reassured that your fallopian tubes aren’t blocked:

A clear fallopian tube and an ovary and tube positioned to work effectively together aren’t necessarily the same thing.

So having deep endometriosis doesn’t mean you won’t conceive naturally. What matters is understanding whether your disease has affected the anatomy or function needed for conception – rather than assuming your fertility from the stage of endometriosis written in your notes.

What If Endometriosis Isn’t the Only Thing Affecting Your Fertility?

When you already have an endometriosis diagnosis, it’s very easy for every fertility problem to get put into the same box.

You’re not getting pregnant because you have endometriosis. Your inflammation is because you have endometriosis. Your painful or irregular cycles are because you have endometriosis.

Sometimes that’s part of the explanation. But it can also stop us asking an important question:

What else is happening alongside your endometriosis that could matter to your fertility too?

For example, if you have signs of insulin resistance or irregular ovulation, that matters whether or not you have endometriosis. If your thyroid function isn’t optimal for pregnancy, treating the endometriosis doesn’t make that irrelevant. And if there are other patterns in your symptoms or investigations that don’t neatly fit the endometriosis diagnosis, those deserve to be understood rather than automatically being put down to endometriosis too.

The point isn’t to find a long list of hidden “root causes” and try to fix every one before you conceive.

It’s to identify the factors that are actually showing up in your history, symptoms and investigations – particularly when addressing them may be relevant to your fertility as well as your endometriosis.

Because if you’re going to spend precious preconception time changing something, there should be a good reason why that particular thing matters to you.

Endometriosis, Egg Quality and Embryo Development

If you’ve had a disappointing IVF cycle, it can be very easy to connect the dots yourself:

I have endometriosis. We didn’t get many good embryos. My endometriosis must have damaged my eggs.

But having endometriosis doesn’t automatically mean you have poor-quality eggs – and a disappointing IVF result doesn’t necessarily tell you that either.

Endometriosis is associated with inflammation and oxidative stress that may affect the environment in which follicles and eggs develop. Research has found changes in follicular fluid, mitochondrial function and the cells that support the developing egg, which may help explain why egg development can be affected in some women with endometriosis.

But that is only one part of the picture.

Your age remains one of the strongest influences on egg quality. And the number of eggs retrieved, how many are mature, how many fertilise and how embryos develop are different stages of the process. When something hasn’t gone as expected, where that drop-off occurs can give you much more useful information than simply labelling the whole cycle “poor egg quality”.

For example, repeatedly retrieving fewer eggs than expected raises different questions from retrieving a good number of mature eggs but seeing a significant drop between fertilisation and embryo development.

That distinction matters because it changes what may actually be worth addressing before you try again.

And while age is something you can’t change, the environment in which your eggs develop can potentially be influenced.

Depending on your individual picture, that may include nutrition, nutritional medicine, nutrient status, metabolic health, oxidative stress, sleep and other lifestyle factors. The aim isn’t to promise that changing these things will produce better embryos, but to identify where there may be realistic opportunities to support the environment in which your eggs are developing.

So rather than leaving a disappointing cycle thinking “my endometriosis has damaged my eggs”, you can start asking a much more useful question:

What are my results actually telling me – and which parts of that picture can I realistically influence before I try again?

It’s a very different starting point from trying to create the “perfect” egg. It’s about supporting what is genuinely modifiable without losing valuable reproductive time chasing things that may not change your outcome.

Adenomyosis Can Make Implantation More Difficult in Women With Endometriosis

If your painful periods, heavy bleeding or pelvic pain have already been explained by endometriosis, there may have been little reason to question whether adenomyosis is present too.

Yet the two conditions commonly occur together – and when you’re trying to conceive, knowing whether you have both can matter.

Adenomyosis occurs when tissue similar to the lining of the uterus is found within the muscular wall of the uterus. Because its symptoms can overlap so closely with endometriosis, it can be difficult to distinguish between the two from symptoms alone.

The important difference for fertility is that adenomyosis affects the uterus an embryo needs to implant into.

Research has associated adenomyosis with lower implantation, pregnancy and live birth rates, as well as a higher risk of miscarriage. Research looking specifically at women with both conditions also suggests that adenomyosis may make successful implantation and live birth more difficult than when endometriosis is present alone.

So if adenomyosis is part of your picture, improving egg or embryo quality may not address the whole fertility problem.

That doesn’t mean adenomyosis explains every unsuccessful transfer or miscarriage. But because it commonly sits alongside endometriosis, knowing whether it is present may change what deserves attention before you move forward with fertility treatment.

And that is the more useful question: not simply “How is my endometriosis affecting my fertility?” but “Do I actually have the full picture yet?”

When You Can Get Pregnant, But Keep Miscarrying

If you have endometriosis and you can get pregnant, there can be some reassurance in knowing that conception is possible.

At least I know I can get pregnant.

But when those pregnancies repeatedly don’t continue, getting pregnant may no longer be the part of your fertility picture that needs the most attention.

Research suggests women with endometriosis may have a higher risk of miscarriage, although that doesn’t mean endometriosis is necessarily the reason for your losses.

What it does mean is that it can be worth looking more closely at the parts of your endometriosis picture that may be relevant to maintaining a pregnancy.

For some women, adenomyosis may be one part of that picture, as it has been associated with a higher risk of miscarriage as well as difficulties with implantation. In other cases, there may be hormonal, uterine or entirely separate factors that warrant investigation. And sometimes the explanation may have nothing to do with endometriosis at all.

The important thing is not to let the fact that you can conceive stop the investigation when staying pregnant has become the problem.

Because after a miscarriage, the instinct is often to focus on getting pregnant again – tracking ovulation more closely, improving egg quality, changing supplements or trying another transfer.

But after repeated losses, the question has now changed from “How do I get pregnant again?” to “What could be getting in the way of this pregnancy continuing?”

That shift can change what gets investigated, what deserves attention before you try again and where your time and energy are best spent.

If You’re Having Endometriosis Surgery to Improve Fertility, What Should Happen Before It?

If you’re considering endometriosis surgery because you’re struggling to conceive, there is often a very clear plan:

Remove the endometriosis, recover from surgery, then start trying for a baby.

And depending on where your endometriosis is located, surgery may absolutely be an important part of improving your chances of natural conception – particularly if adhesions or disease are interfering with the relationship between your ovaries and fallopian tubes.

But if fertility is the reason you’re having surgery, there is another question worth asking before you get there:

Is there anything else in your endometriosis picture that could also be making it harder for you to conceive?

Because surgery can remove lesions and improve anatomy. What it doesn’t necessarily change are the wider biological patterns that may be sitting alongside your endometriosis – and some of those may matter to fertility too.

If you’ve already identified things such as irregular ovulation, insulin resistance, significant nutrient deficiencies, missed infections, thyroid dysfunction or increased oxidative stress, those factors don’t suddenly become irrelevant because your endometriosis has been surgically removed.

This is where the time before surgery can become valuable rather than simply something you have to wait through.

It can give you an opportunity to identify the most obvious modifiable factors in your picture and begin supporting the ones that may matter to both your endometriosis and your fertility – so surgery isn’t being asked to solve parts of the fertility picture it was never designed to change.

That doesn’t mean delaying a surgery you need while you spend six months trying to “fix” every possible root cause. Your age, ovarian reserve and fertility timeline still matter, and sometimes moving quickly is the right decision.

It means making the months you do have count.

If surgery is intended to give you a better chance of pregnancy, the preparation for that pregnancy doesn’t have to begin after surgery.

How Long Should You Try Naturally With Endometriosis?

Being told that women with endometriosis can conceive naturally can be reassuring.

But when another month passes without a positive pregnancy test, reassurance isn’t really what you need. You need to know how long it makes sense for you to keep trying.

Because there is a difference between being capable of conceiving naturally and having enough time for continuing to try naturally to be the best strategy.

If you’re younger, have a reassuring ovarian reserve, your fallopian tubes appear clear, ovulation is occurring and there are no significant sperm factors, giving natural conception more time may be entirely reasonable.

But the same advice may look very different if you’re in your late 30s, have a lower ovarian reserve, an endometrioma or previous ovarian surgery, you’ve already been trying for a considerable period of time, or there are additional fertility factors involved.

Endometriosis doesn’t automatically mean you need IVF. But it can mean that time deserves more consideration.

And this is where waiting for an arbitrary number of months before reassessing can sometimes be less useful than looking at what those months actually mean in the context of your fertility.

If you have time, that window can also be used intentionally – addressing the modifiable factors in your fertility picture while you continue trying naturally, rather than feeling as though you’re simply waiting to see what happens.

If time is more limited, spending many months trying to perfect every aspect of your health before considering fertility treatment may cost you something that nutrition and supplements can’t give back.

Continuing to try naturally should feel like an active decision – not simply the default because nobody has given you a reason to reassess it. And that decision still needs to make sense for the fertility window you actually have.

Does Having Endometriosis Mean IVF Is Your Next Step?

When endometriosis is part of the reason you’re struggling to conceive, IVF can start to feel inevitable.

And for some women, moving directly to conventional IVF will make sense. But your endometriosis diagnosis alone doesn’t tell you how much fertility intervention you need.

The better starting point is understanding what is actually getting in the way of pregnancy in your particular case – and which treatment is most likely to help you get around it.

IUI and Endometriosis

If you have minimal or mild endometriosis, your fallopian tubes appear clear and there aren’t other significant fertility barriers, IUI with ovarian stimulation may still be an option.

And if you’re someone who would prefer to try something less invasive before IVF, that can feel like an appealing next step.

But gentler only works in your favour if it still makes sense for the fertility problem you’re trying to solve.

If several rounds of IUI are unlikely to overcome that problem, you may simply be trading less intervention now for more lost time later.

What About “IVF Lite”?

If you’re already worried about putting your body through IVF – particularly if hormonal changes tend to flare your endometriosis symptoms – there may be a middle ground worth knowing about.

“IVF Lite” generally refers to IVF using milder ovarian stimulation and lower doses of fertility medication than conventional IVF. For some women with endometriosis, that can mean less exposure to the high-oestrogen environment of ovarian stimulation and potentially fewer medication-related side effects.

But using less medication isn’t automatically better.

A milder protocol may also mean retrieving fewer eggs, so the decision becomes whether reducing the treatment burden still gives you a realistic chance of achieving what you need from that cycle.

Maybe you want to minimise medication because you know how strongly your body responds to hormonal changes. But you also don’t want to look back after several cycles and wonder whether choosing the gentler route cost you time you didn’t really have.

That’s the balance you’re trying to find – not automatically choosing the least intervention possible, or the most aggressive treatment simply because you have endometriosis, but finding the right amount of intervention for the fertility picture – and the body – you actually have.

Preparing for IVF When You Have Endometriosis

Once you’ve decided IVF is the right next step, it’s very easy for the focus to narrow.

How many follicles are growing? How many eggs were retrieved? How many fertilised? How many embryos made it to Day 5?

Those numbers matter. But you still have to get your body through the treatment that produces them.

And when you have endometriosis, that can deserve some thought before your first injection.

When IVF Hormones Flare Your Endometriosis Symptoms

If you already know that your pain, bloating, migraines or other symptoms tend to worsen with hormonal changes, you may be worried about what ovarian stimulation will feel like.

IVF medications stimulate multiple follicles to develop at once, which can raise oestrogen considerably above the levels you would usually experience during a natural cycle.

That doesn’t mean IVF will make your endometriosis permanently worse. But it does mean that some women may notice a temporary increase in symptoms during or after treatment.

Rather than waiting until you’re halfway through a cycle and struggling, your previous response to hormonal changes can give you useful clues beforehand.

Which symptoms tend to appear first? What has helped you manage them previously? Are there symptoms your fertility specialist needs to know about? And what might make the stimulation and recovery period easier for you?

Because “the IVF worked” and “I coped well with the IVF” are two different outcomes – and both matter when you’re the person going through it.

IVF Can Bypass Some Endometriosis-Related Fertility Barriers – Not All of Them

IVF can bypass some of the problems endometriosis creates. For example, fertilisation happens outside your body, so egg and sperm no longer depend on the fallopian tube being able to bring them together.

But that doesn’t mean everything we’ve discussed up to this point stops mattering once IVF begins.

The useful distinction is knowing what IVF is solving for you – and what it isn’t.

If there are parts of your fertility picture that IVF will bypass, you may not need to spend valuable time trying to change them first. If there are factors that remain relevant to egg development, implantation or how you tolerate treatment, those may deserve attention alongside it.

Preparing for IVF with endometriosis isn’t about finding more things to “fix” before you’re allowed to start.

It’s about going into treatment knowing where your effort is actually worth putting – and where IVF is already doing the work for you.
