Why Inflammation Could Be Silently Hurting Your Fertility
Chronic, low-grade inflammation is one of the most overlooked factors that can make it harder to conceive, both naturally and through IVF.
When your body is inflamed, it is constantly fighting internal stress. This inflammation can interfere with hormone balance, egg quality, sperm health, and even implantation.
The good news is that your diet is one of the most powerful tools to reduce inflammation and improve your chances of conception, and this is where the anti-inflammatory diet can help.
What Is the Anti-Inflammatory Diet?
The Anti-Inflammatory Diet doesn’t have to be a strict plan, many people will ave different opinions when it comes to this style of eating – but in my opinion it is a very useful base to start with when building your fertility plate. It is a science-backed way of eating that focuses on nourishing your body with foods that calm inflammation while cutting back on those that trigger it.
Think of it as a nutrition starting point for fertility, that you can then expand on with other diet inclusions (rather than follow strictly)
The Two Core Principles:
- Eat more foods that reduce inflammation, such as fruits, vegetables, healthy fats, and whole grains.
- Limit foods that promote inflammation, including processed snacks, refined carbohydrates, and added sugars.
The Mediterranean Diet is the most well-studied example of an anti-inflammatory eating pattern and has been shown to support fertility, PCOS management, and IVF success.
The Evidence: How Inflammation Affects Fertility
Research using the Dietary Inflammatory Index (DII), which measures how inflammatory a person’s diet is, shows that people with the most inflammatory diets have a 61% higher risk of infertility compared to those who eat more anti-inflammatory foods. (Review Here)
Inflammation disrupts reproductive function on several levels.
For Women:
- Hormonal imbalance leading to irregular or anovulatory cycles
- Reduced egg (oocyte) quality
- A less receptive uterine environment, making implantation more difficult
For Men:
- Sperm DNA damage and oxidative stress
- Reduced sperm count and motility
- Abnormal sperm morphology (shape)
Chronic inflammation affects every stage of reproduction, from egg and sperm development to successful implantation.
Fertility-Boosting Foods on the Anti-Inflammatory Diet
Here’s what to eat more of and why each group supports fertility:
| Food Group | Examples | How It Supports Fertility |
|---|---|---|
| Omega-3 Fats | Salmon, sardines, chia seeds, walnuts | Fights inflammation and improves egg and sperm membrane quality |
| Antioxidant-Rich Produce | Berries, citrus fruits, spinach, kale | Protects egg and sperm DNA from oxidative damage |
| High-Fibre Foods | Oats, quinoa, lentils, vegetables | Balances blood sugar and hormones; supports gut health |
| Plant Proteins | Beans, chickpeas, lentils, tofu | Reduces inflammation and supports steady energy |
| Healthy Fats | Olive oil, avocado, nuts | Promotes hormone production and reduces inflammatory markers |
Simple Anti-Inflammatory Meal Ideas
You don’t need to overhaul your entire diet. Small, consistent changes make a big difference.
Breakfast:
- Greek yoghurt with berries, chia seeds, and walnuts
- Whole-grain toast topped with smashed avocado and eggs, or home-made baked beans
Lunch:
- Chickpea and salad wrap with olive oil dressing
- Quinoa bowl with chicken, roasted vegetables, and avocado
Dinner:
- Baked salmon with tomato and olive salsa
- Prawn curry with brown rice and steamed greens
Snacks:
- Handful of almonds and blueberries
- Vegetable sticks with hummus
Foods That Trigger Inflammation
To calm inflammation and support reproductive hormones, reduce or avoid the following:
- Refined carbohydrates such as white bread, pastries, and white rice
- Added sugars in soft drinks, sweets, and processed cereals
- Processed meats such as bacon, sausages, and deli meats
- Unhealthy fats including trans fats, margarine, and shortening
- Highly processed convenience foods and fried takeaway meals
Even reducing these foods by half can improve insulin sensitivity, hormone balance, and reproductive outcomes within weeks.
Why I Don’t Recommend Following One Diet Style Perfectly
While the Anti-Inflammatory Diet provides an excellent framework for fertility nutrition, I don’t believe in following one diet style to the letter. Every body and every fertility journey is unique.
Red meat and full-cream dairy, for example, often get excluded from strict versions of anti-inflammatory or Mediterranean diets, but I see clear nutritional benefits when these foods are included in moderation.
Red meat provides highly bioavailable iron, zinc, and vitamin B12, all of which are essential for ovulation, red blood cell production, and early embryo development.
Full-cream dairy offers calcium, iodine, vitamin D, and high-quality protein that can support hormone production and egg quality.
The key is to choose quality sources:
- Opt for lean, grass-fed red meat 1–2 times per week.
- Choose full-fat, minimally processed dairy such as Greek yoghurt or milk without added sugars.
Nutrition for fertility is about balance, not perfection. An overly restrictive approach can sometimes do more harm than good, especially if it limits critical nutrients needed for reproductive health.
Clinical Benefits: How an Anti-Inflammatory Diet Supports Fertility
1. PCOS and Hormone Balance
Women with PCOS often experience inflammation and insulin resistance. Studies show that a Mediterranean-style, low-glycaemic diet helps regulate menstrual cycles, support ovulation, and improve insulin control.
2. IVF Success
Women who follow an anti-inflammatory, Mediterranean-style diet before and during IVF tend to have better-quality embryos and higher pregnancy and live birth rates.
3. Endometriosis and Pregnancy Outcomes
An anti-inflammatory diet may help reduce pelvic pain and lower the risk of preterm birth by up to 75% when followed before conception.
4. Male Fertility
A diet rich in antioxidants and omega-3 fats improves sperm concentration, motility, DNA integrity, and overall hormonal balance.
Getting Started with a Fertility-Friendly Anti-Inflammatory Plan
Start with small, sustainable changes:
- Add one extra serve of vegetables at each meal.
- Swap red meat meals for oily fish twice per week.
- Cook with extra virgin olive oil instead of butter.
- Replace sugary snacks with nuts, fruit, or yoghurt.
Each positive change helps reduce inflammation, balance hormones, and improve your overall reproductive health.
