For the millions of women living with endometriosis, navigating the path to pregnancy can already feel like an uphill battle. When you add the lingering anxiety that the condition might be affecting the quality of your eggs, it’s enough to make anyone want to pull the covers over their head.
But what does the research say? Is it a definitive fact that endometriosis impacts egg quality, or is the reality more nuanced? Ahead, we dive into the latest data to separate fact from fiction.
Can endometriosis cause poor egg quality?
Research does show markers of reduced egg quality in endometriosis. For instance, a 2026 review in Cells suggests that the environment in which the eggs mature is highly compromised in those with endometriosis and that endometriosis induces microscopic and genetic "microdamage" to the egg itself.
But these results come from lab studies, which means a highly controlled, artificial environment that may not yield the same results in the real world. In fact, IVF outcomes can be similar to those without endometriosis, according to a 2023 study in the Journal of Assisted Reproduction and Genetics.
This distinction is important because you want to know if you can have a baby, not just what your eggs look like under a microscope. In reality, your ability to conceive with endometriosis depends on multiple factors: stage, location, whether you have cysts, and your overall ovarian reserve.
What the studies actually say about endometriosis and egg quality
Research shows higher oxidative stress in follicular fluid, inflammatory markers, and mitochondrial dysfunction in eggs from women with endometriosis. The 2026 review in Cells found evidence of impaired oocyte quality at the cellular level.
But meta-analyses, like this one in the Journal of Gynecology Obstetrics and Human Reproduction, show no significant difference in IVF success rates when comparing women with endometriosis to those without.
The disconnect: Laboratory markers don't always translate to clinical outcomes. What this means is that your eggs may show stress markers, but that doesn't necessarily mean they can't create healthy embryos.
The real determining factors are your age, stage, AMH level (the quantity of eggs in your ovarian reserve), cysts, and whether you've had ovarian surgery, according to research in the European Journal of Medical Research.
Does endometriosis affect egg count?
Yes, endometriosis can affect your egg count. This is especially if you have endometriomas (a type of cyst that develops deep within the ovaries that’s filled with old blood and endometrial-like tissue). That’s because endometriomas are associated with lower AMH and reduced antral follicle count (an estimate of the number of eggs you have remaining), according to research in Facts, Views & Vision in ObGyn.
Additionally, chronic inflammation from endometriosis can damage ovarian reserve over time, and surgery to remove endometriomas can further reduce egg count, according to research in Clinical and Experimental Reproductive Medicine.
So, if you’re considering freezing your eggs, doing so earlier rather than later ensures you preserve a higher volume of healthy eggs.
Can endometriosis kill your eggs?
Endometriosis doesn’t “kill” your eggs in the literal sense, but chronic inflammation creates a hostile environment for them:
Elevated reactive oxygen species (ROS) can damage DNA in developing eggs.
The inflammatory cytokines and immune cells in the peritoneal fluid may interfere with fertilization.
Endometriomas damage healthy ovarian tissue and follicles.
But here's the key: This is a process that happens over time, not overnight. Early intervention (egg freezing, treatment, surgery timing) can make a difference.
Silent endometriosis and egg quality: What to know
If you have silent endometriosis, aka you have minimal symptoms but the disease is still present, is your egg quality still poor? Yes, even mild, asymptomatic endometriosis can affect the pelvic environment, according to the American Society for Reproductive Medicine.
Some women have Stage 3-4 endometriosis with minimal pain; others have Stage 1-2 with debilitating symptoms, according to Johns Hopkins Medicine. Pain level doesn't correlate with fertility impact — you can have "silent" endometriosis affecting your eggs.
If you have unexplained infertility, a pelvic MRI can be a good starting point before moving forward with a laparoscopy, which remains the definitive diagnostic tool.
Can you freeze your eggs if you have endometriosis?
Yes, you can freeze your eggs if you have endometriosis. In fact, it’s often recommended because it’s a proactive way to approach fertility before the condition potentially impacts your eggs, according to The Endometriosis Foundation.
Research, like this article in the Journal of Assisted Reproduction and Genetics, shows there are successful outcomes for egg freezing with endometriosis. “Freezing embryos or unfertilized [eggs]…offers a real chance of future pregnancy when a good amount of [eggs] or embryos has been stored,” the authors wrote.
However, timing matters. Research suggests freezing your eggs before endometriosis excision surgery if possible because surgery can reduce egg count by up to 50 percent. Additionally, women under 35 with good ovarian reserve see best results, according to an article in the Journal of Clinical Medicine.
You may need multiple IVF cycles to get an adequate number of eggs if your reserve is already compromised, according to the American Society for Reproductive Medicine. Special protocols, like low-estrogen stimulation, can be used to avoid making endometriosis symptoms flare up during egg retrieval.
When to consider freezing
Questions Women Are Asking
When considering the timing of freezing your eggs, it’s important to talk with your gynecologist and a fertility specialist, as everyone is different. With that being said, here are instances you may want to consider freezing your eggs:
If you have large endometriomas (especially bilateral)
Before any planned excision surgery
If you're under 35 with decent AMH but not ready for kids yet
If you want to preserve fertility while focusing on pain management and treatment
Can you be an egg donor if you have endometriosis?
Many clinics, like Egg Donor America, recommend against egg donation if you have endometriosis. This is because endometriosis affects both egg quantity and quality, reducing retrieval success.
Additionally, there are health risks involved, according to Egg Donor America — hormonal stimulation can worsen endometriosis symptoms, and retrieval is more complicated with cysts and adhesions.
If you have endometriosis and want to help others, you may want to consider being involved in advocacy or support groups rather than egg donation. But with that being said, it’s always a good idea to check with the specific agency you’re interested in to make sure of their policies.
What this means for your fertility timeline
If you're diagnosed with endometriosis young (in your 20s or early 30s) without endometriomas and want kids, time is on your side, but it’s important not to wait too long to freeze your eggs to ensure you can preserve a higher volume of healthy eggs. If you have endometriomas, you may want to seriously consider freezing your eggs before any surgery.
If you're over 35 with endometriosis, age compounds the issue of declining egg quality, so it’s important to move fast in freezing your eggs if that’s what you want to do.
If surgery is recommended, the timing relative to egg freezing is highly patient-specific: some women can freeze first, others may need surgery beforehand. This decision requires close communication between your RE and the surgeon performing the procedure, based on your individual situation and goals.
Women with endometriosis can conceive naturally, according to the Endometriosis Foundation of America, but IVF success rates are comparable when adjusted for age and ovarian reserve.
The bottom line: There’s no need to panic if you have endometriosis and want children, but don't procrastinate on family planning either.
The real questions to ask your doctor
It’s important to consult your gynecologist and a reproductive endocrinologist's opinion when it comes to getting pregnant with endometriosis; they see this through different lenses. Here are a few questions to ask both of them:
What stage is my endometriosis, and where is it located?
Do I have endometriomas? If so, how large and on one or both ovaries?
What's my AMH level and antral follicle count?
Should I freeze eggs before any planned surgery?
What's your recommendation: try naturally, go straight to IVF, or freeze first?
If I need surgery, how will it likely affect my ovarian reserve?
Managing expectations without losing hope
Yes, endometriosis can affect egg quality at the cellular level, but that doesn't mean you can't get pregnant. The biggest impacts are on egg count (especially with endometriomas) and the pelvic environment (inflammation, adhesions).
Additionally, IVF outcomes for women with endometriosis are often comparable to those without when controlling for other factors.
It's also worth noting that surgical intervention isn't the only option. For women not seeking immediate pregnancy, medical suppression of endometriosis is an important part of management, since endometriomas can recur if surgery is pursued without ongoing treatment.
Timing is everything, though. You should freeze eggs as soon as you know you want children, especially if you’re over 35.
Many women with endometriosis go on to have healthy pregnancies — the key is working with doctors who understand both the disease and your reproductive goals. It’s a complicated situation, but it’s not a hopeless one.
