How to Improve Egg Quality: What Really Helps for IVF and Fertility
Egg quality is one of the most important factors in fertility and IVF success. While it cannot be changed dramatically, healthy habits may help support it — and understanding what egg quality means helps set realistic expectations.
What is egg quality?
Egg quality mainly refers to an egg's chromosomal health and its ability to fertilize and develop into a healthy embryo. Unlike egg quantity (reflected by tests such as AMH), egg quality cannot be measured directly by a single test.
How does age affect egg quality?
Age is the strongest factor. As women get older, the proportion of eggs with chromosomal errors rises and egg numbers fall. This is why fertility and IVF success tend to decline with age, particularly after the late 30s.
How to support egg quality
- Balanced nutrition rich in fruit, vegetables, whole grains and healthy fats.
- Avoid smoking and limit alcohol, which can harm egg health.
- Maintain a healthy weight and stay physically active.
- Discuss supplements such as folic acid with your doctor before starting them.
Can you improve egg quality naturally?
Healthy habits may help support egg health, but no method can reverse age-related changes or guarantee improvement. The most reliable step is timely evaluation and, where relevant, not delaying treatment.
What matters for IVF
In IVF, egg quality influences fertilization, embryo development and the chance of a healthy pregnancy. Where appropriate, methods such as genetic testing (PGT) can help select the healthiest embryo. For those wanting to preserve future chances, egg freezing at a younger age is an option.
When to seek advice
If you are concerned about egg quality or ovarian reserve — especially over age 35 — an early assessment with tests such as AMH and ultrasound can guide personalized planning.
