Understanding Endometriosis and Its Impact on Fertility
The statistics show that endometriosis (a.k.a. endo) can make it harder to conceive. An estimated 30-50% of women with this condition will also struggle with infertility. But, keep reading! There’s more to this story than scary statistics.
What is endometriosis?
The unfortunate reality is that the root causes of endometriosis are still not fully understood.
What we do know is that endo is highly complex, with hormonal, immunological and genetic factors, all at play.
Endometrial tissue (a.k.a. the uterine lining) typically grows inside the uterus and sheds through the vagina each menstrual cycle. The defining characteristic of endo is the endometrial tissue growing outside of the uterus.
This endometrial tissue grows each month, and then sheds every time you get your period, just like the tissue inside your uterus. However, the tissue cannot flow out your vagina, and instead gets trapped in your abdominal cavity.
As a result, the trapped tissue can get stuck to various organs, like your bladder, intestines, etc., causing irritation, inflammation, scarring, and often intense pelvic pain.
Symptoms of Endometriosis
While symptoms vary in severity, common signs include:
- Pelvic pain – Often chronic and worsening around menstruation or during ovulation.
- Painful periods – Severe cramping that may begin before and extend after your period.
- Pain during or after sex – due to endometrial-like tissue in the pelvic cavity.
- Heavy or irregular menstrual bleeding – Periods may be longer, heavier, or involve spotting between cycles.
- Gastrointestinal issues – Bloating, constipation, diarrhea, or nausea, especially during menstruation. (IBS is often a symptom of endo)
- Painful bowel movements or urination – Symptoms may intensify during menstruation if endometrial tissue affects the bladder or intestines.
- Fatigue – Chronic inflammation and hormonal imbalances can contribute to low energy levels.
- Infertility – Endometriosis can cause scarring, inflammation, and hormonal disruptions that interfere with conception.
The complex and aggravating thing about endo, making it so hard to diagnose, is that it can also be asymptomatic. Many women live for years with no idea they have this condition because they don’t have any symptoms.
Additionally, since endo symptoms can mimic other conditions, like IBS, it’s often missed by healthcare providers.
How does endometriosis impact fertility?
Endometriosis can impact fertility in several key ways.
- First, when the immune system gets continuously triggered, inflammation becomes the new norm, worsening egg quality, preventing ovulation and implantation, and making conception overall more challenging.
- Second, the formation of adhesions and scar tissue can distort pelvic anatomy, potentially blocking the fallopian tubes or affecting the movement of eggs and sperm.
- Third, hormonal imbalances, particularly elevated estrogen levels, can disrupt the delicate hormonal interplay necessary for ovulation and a receptive uterine lining.
- Fourth, oxidative stress and reduced mitochondrial function can compromise egg health, leading to lower-quality embryos.
- Finally, poor progesterone receptivity—a common issue in endometriosis—can result in a less hospitable uterine environment, decreasing the chances of successful implantation. (Read more: How to improve progesterone levels with food)
Research suggests that reducing inflammation and supporting hormonal balance are key to managing endometriosis, which is where targeted supplements can play a supportive role.
Supplements for better fertility with endometriosis
No supplement is a cure for endometriosis. However, strategic supplementation, as part of your medical and lifestyle treatments, can help reduce inflammation, balance hormones, and improve overall fertility.
When choosing supplements, it’s important to balance those with scientific support for their benefits with your personalized needs.
Vitamins C, E and D, as well as omega-3 fats and magnesium repletion should be a part of every protocol for women with endo. We know that when these essential nutrients get too low, symptoms such as cramping and egg quality, get worse.
Then there is a list of supplements with benefits for reducing inflammation and pain, including: curcumin, NAC, quercetin, resveratrol, and EGCG. Work with your healthcare provider to determine which ones will best serve you.
This blog is not medical advice and your first step, before making any change to your supplements, should be to consult your healthcare team.
Vitamins C and E
Already well established as antioxidants known to improve egg and sperm quality, vitamin E and vitamin C supplements have also been shown to help specifically with endo and fertility by reducing oxidative stress and inflammation.
When taken in combination, 1,200 IU of vitamin E and 1,000 mg of vitamin C daily for eight weeks, women reported less pain with their period and with sex (compared to a placebo group).
By lowering oxidative stress, these antioxidants help to improve egg quality, support successful implantation, and boost overall fertility.
Note: The therapeutic doses of Vitamins E and C recommended for endo are included in my most highly-recommended prenatal for fertility, made by FullWell.
Omega-3 Fatty Acids
Omega-3 supplementation can improve blood flow to the uterus, support progesterone levels and reduce inflammation.
The anti-inflammatory properties are particularly powerful for gals with endo, by reducing the size and number of endometriotic lesions, which can both alleviate pain and improve chances of conception.
Research suggests that women taking omega-3 supplements had a 1.5 times higher probability of conceiving compared to those not supplementing.
Be sure to take an omega-3 rich in eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), from fish or algae sources.
Beware of claims that nuts and seeds, like chia, flaxseeds and walnuts, are a good source of omega-3s. In reality, they contain a different kind of omega-3 fat, called ALA. Less than 10% of that ALA gets converted to the highly anti-inflammatory DHA and EPA.
A high-quality fish oil or algae–based omega-3 is needed to reduce inflammation and improve fertility.
Vitamin D
Vitamin D is made by your skin when exposed to the sun, and found in select foods, such as fortified dairy, salmon and egg yolks.
Research exploring the impact of vitamin D supplementation on endo symptoms and fertility outcomes presents mixed findings.
A review of the research concluded that vitamin D supplementation did not significantly alleviate period-pain or non-cyclic pelvic pain in women with endo, nor did it improve outcomes in IVF treatments.
However, it is still an essential part of your endo treatment plan to make sure your serum vitamin D levels are optimal because:
- It is well established that vitamin D plays a crucial role in regulating the immune system, taming inflammation and controlling auto-immune reactions (like endo).
- We also know from observational studies that women with endometriosis are more likely to have lower levels of vitamin D.
- We also have gold-standard research trials showing that women with endo who took 5,000 IU of vitamin D3 each day, had significantly less pelvic pain, compared to women with endo who took a placebo.
Take home: Test don’t guess.
Test your vitamin D levels and make sure they’re in the optimal range for hormone health, immune function and fertility. If levels are below-optimal, you’re likely to benefit from vitamin D supplementation.
Magnesium
While direct studies on magnesium supplementation for endometriosis are scarce, its benefits make it a promising addition to your fertility and endo supplement routine.
First, for pain relief. Magnesium can help relax smooth muscles, i.e. less cramping and pelvic pain.
Magnesium also helps reduce inflammation and oxidative stress, both of which are elevated in endometriosis.
Magnesium glycinate is the form with the highest bioavailability, while gentle impact on the digestive system.
Other fertility supplements to consider for endometriosis:
Emerging research suggests that certain anti-inflammatory supplements including, curcumin, N-acetylcysteine (NAC), quercetin, resveratrol, and epigallocatechin gallate (EGCG), may offer additional benefits for managing endometriosis and supporting fertility.
Curcumin
Derived from turmeric, the bright yellow spice in curry, curcumin is another potent anti-inflammatory agent. By helping to lower inflammation, it could help alleviate endo symptoms and support overall better fertility.
Research suggests that curcumin can slow the growth of endometrial cells and reduce the estrogen that fuels endometriosis progression.
A typical recommended dosage is 500–1,000 mg per day.
N-Acetylcysteine (NAC)
NAC is known for its antioxidant properties and its ability to support detoxification. By reducing oxidative stress and supporting a balanced inflammatory response, NAC can be a major win for women with endo, especially if trying to conceive.
Research involving women with endometriosis revealed that NAC supplementation led to a reduction in lesion size, decreased pelvic pain, and (!) an increased rate of pregnancy!
The study gave each participant 600 mg of NAC three times daily (totaling 1,800 mg per day) for three months. This regimen was associated with significant improvements in symptoms and fertility outcomes.
Quercetin
Quercetin is an antioxidant with anti-inflammatory benefits, naturally found in various fruits and vegetables like apples, berries, cauliflower and onion.
Studies have shown that quercetin supplementation can halt the growth of endometrial cells, suggesting its potential as a natural therapeutic agent for endometriosis.
While specific dosage guidelines are not well-established, quercetin supplements typically range from 500–1,000 mg per day.
Resveratrol
Resveratrol, another anti-inflammatory compound, called a polyphenol, is present in red grapes and berries (resveratrol is what gives red wine its health halo).
Although more research is needed, there is evidence that resveratrol may slow the spread of endometrial cells and reduce the formation of new blood vessels that support lesion growth.
These actions could potentially alleviate endometriosis symptoms and improve fertility. While more research is needed to establish optimal dosing, studies have used doses ranging from 30–150 mg per day.
Epigallocatechin gallate (EGCG)
Epigallocatechin gallate (EGCG), the active compound in green tea, has anti-inflammatory and antioxidant properties.
Animal studies have shown that EGCG can reduce the growth of endometrial implants and reduce estrogen production, suggesting its potential in managing endometriosis.
Although human studies are limited, these findings are promising. Green tea extracts standardized to contain 50–75% EGCG are commonly used, with typical dosages ranging from 200–400 mg per day.
Which fertility supplements for endometriosis are right for you?
When considering these supplements, it’s crucial to recognize that individual responses can vary, and the efficacy may differ based on personal health profiles and the severity of endometriosis.
Combining certain supplements may offer synergistic benefits; for example, pairing curcumin with quercetin could enhance anti-inflammatory effects. However, clinical studies on combined supplementation are scarce, and even fewer have been done specifically on women with endo.
Safety Considerations and Professional Guidance
It’s important to underscore that while these supplements have scientific backing, they are not a substitute for medical treatment. Individual needs vary, and the best approach is always one that is personalized with the guidance of your healthcare provider. They can help ensure that any supplementation is safe, appropriate, and aligned with your overall health goals.
Final Thoughts
Choosing the best fertility supplements for endometriosis is about more than just adding a pill to your routine—it’s about a holistic approach including support for your immune system, hormone balance and overall reproductive health.
With science supporting the use of many vitamins, minerals and antioxidants, there are supplements to help manage your endometriosis symptoms by bringing down inflammation, supporting hormonal balance, and boosting fertility.
