How to Improve Egg Quality?
Share
The fertilization of an egg by sperm, the implantation of the fertilized embryo in the uterus, and its healthy development into a baby is a truly miraculous process. However, there are certain issues that may disrupt this process, and egg quality is one of the most important of them.
Poor egg quality can prevent pregnancy from occurring or may lead to the pregnancy not continuing. Gaining detailed information about egg quality and learning how to improve it can help pave the way for a healthy pregnancy.
So, how can egg quality be improved and which vitamin supplements should be taken before pregnancy? Here are the most effective natural methods and supplements supported by scientific studies:
What Is Egg Quality?
Egg quality, which is critically important for fertility, refers to whether an egg is chromosomally normal or abnormal. A high-quality, normal egg contains 23 chromosomes. When such an egg is fertilized by a healthy sperm, it has a high chance of developing into an embryo, implanting in the uterus, and resulting in a successful pregnancy.
Egg quality is determined by both environmental and genetic factors. Some of the factors that can negatively affect egg quality include:
- Endometriosis (chocolate cyst)
- Receiving chemotherapy
- Use of certain medications
- Polycystic ovary syndrome (PCOS) and other ovarian cysts
- Immunological (immune system–related) disorders
- Apart from these, other conditions may also answer the question: “Why does egg quality decrease?”

1. Cellular Health and Energy Support: Comprehensive Supplements
Egg cells need a high amount of energy for fertilization and early development. The following supplements support this process in a multifaceted way:
- Omega-3 Fatty Acids (DHA and EPA)
These are among the most sought-after ingredients for improving egg quality. The combination of DHA and EPA supports the flexibility and integrity of cell membranes and helps reduce inflammation in the body, thereby contributing to a healthier environment around the ovaries. DHA is also vital for the baby’s brain and eye development during pregnancy. However, to see this effect, daily intake should include at least 200 mg of DHA.
- Folic Acid (5-MTHF Form)
Folic acid—especially the highly bioavailable 5-MTHF form—is one of the most important supplements for healthy nutrition and planning in pregnancy. It supports not only the baby’s neural tube development but also the genetic health of the egg cell.
- B Vitamins (B12, B1, B2, B3, B5, B6)
This complex group of vitamins plays a role in the metabolism of reproductive hormones and supports overall fertility. In particular, vitamin B12 in the methylcobalamin form is critical for proper cell division in the egg and for regulating the menstrual cycle.
- Vitamin D
Vitamin D helps support hormonal balance and ovarian function, thereby potentially increasing the chances of pregnancy.
2. Antioxidants and Minerals: Protecting Egg Cells
Protecting egg cells from oxidative stress is key to improving egg quality. The following vitamins and minerals act like a shield for the cells:
- Antioxidants (Vitamin C, Vitamin E, Selenium, and Beta-Carotene)
These help protect the eggs and surrounding ovarian cells from the harmful effects of free radicals. Reducing oxidative stress has a positive effect on both egg reserve and egg quality.
- Iron and Copper
These are essential for healthy red blood cell production and energy levels. By helping reduce the risk of anemia before pregnancy, they support the mother’s preparation for a healthy pregnancy.
- Zinc and Iodine
Zinc plays a role in regulating fertility hormones in both women and men. Iodine is critical for thyroid function and is important for a healthy ovulation cycle and fetal brain development.
3. Electrolyte Balance and Hormonal Support
These minerals help maintain the body’s overall balance and play indirect but important roles in the menstrual cycle and fertility:
- Calcium and Magnesium
They are important for muscle function (including the uterus) and nerve transmission. Magnesium can also help reduce menstrual cramps and pain associated with premenstrual syndrome (PMS).
4. Nutrition and Lifestyle Changes
No matter how important supplements are, the foundation of improving egg quality lies in a healthy lifestyle.
- Antioxidant-Rich Diet
Fresh fruits and vegetables (especially red and purple fruits), whole grains, and legumes meet the body’s antioxidant needs. Green leafy vegetables, in particular, support egg health due to their folate content.
- Healthy Fats
Include healthy fats such as olive oil, avocado, walnuts, and salmon—rich in omega-3—in your diet. These fats are important for hormonal balance and cell membrane health.
- Quit Caffeine, Smoking, and Alcohol
These habits can negatively affect both egg quality and egg reserve. Ideally, you should transition to a healthy diet and lifestyle for pregnancy at least three months before you start trying to conceive.
- Stress Management
High levels of stress can disrupt the ovulation cycle and affect fertility hormones. Yoga, meditation, and adequate sleep are essentials for managing stress during this period.
5. Regular and Balanced Exercise
Regular physical activity, when not excessive, supports ovarian health indirectly.
Increasing Blood Flow
Light to moderate exercise (such as walking and Pilates) increases blood flow to the reproductive organs. Better blood circulation means more oxygen and nutrients are delivered to egg cells.
Ideal Weight
Maintaining a healthy body weight supports hormonal balance. Obesity or being underweight can disrupt the menstrual cycle and cause ovulation problems.
How Is Egg Quality Assessed in Women?
Now that we have briefly touched on the answer to the question “Why does egg quality decrease?”, let’s move on to another question frequently asked by women planning pregnancy: “Which test shows egg quality?” or “How is egg quality measured?”
Although there is no single, specific “egg quality test,” doctors can evaluate egg quality using certain tests and procedures. Some of these include:
Anti-Müllerian Hormone (AMH) Test
AMH levels in the blood help estimate the number of follicles—egg reserves—in the ovaries. Because AMH does not vary significantly during the menstrual cycle, it can be measured at any time.
Follicle-Stimulating Hormone (FSH) and Estradiol Test
A hormone test performed on day 3 of the menstrual cycle allows doctors to assess how well the ovaries produce eggs. FSH or estradiol levels outside the normal range can indicate poor egg quality or decreased egg quantity. If results are not within desired levels, another test called the Clomid Challenge Test may be recommended.
Transvaginal Ultrasound
This is another method used to determine follicle count. The uterus and ovaries are visualized on a monitor via a transvaginal probe.
In addition to these tests, doctors may perform other procedures if necessary. They may take a detailed medical history, ask about your menstrual cycle, and make a comprehensive assessment. Based on the evaluation, a treatment plan can be created if needed.
Does Stress Affect Egg Quality?
Many of us assume that stress negatively affects egg quality, and therefore fertility. However, there is no strong scientific evidence directly supporting this belief. While stress can affect hormones and cause temporary problems, its effects often resolve over time.
If long-term stress is associated with reduced egg quality or reproductive issues, stress is more likely to act as a trigger rather than the primary cause. In other words, while stress is harmful to mental health, it does not directly pose a risk to egg quality. If that were the case, no woman who experienced war or natural disasters would be able to conceive.
Does Smoking Affect Egg Quality?
It is well known that smoking can cause serious health problems, and one of these is impaired ovarian function. Due to the toxic substances in cigarettes, egg numbers may decrease and egg quality may deteriorate. Smoking can accelerate egg loss and lead to earlier menopause.
Even if fertilization occurs, smoking significantly increases the risk of abnormal embryo development. It can also negatively affect the success of IVF treatment. Therefore, if you plan to have a baby now or in the future, it is strongly recommended that you avoid both active and passive smoking.
Do Antibiotics Affect Egg Quality?
Antibiotics are medications used to treat bacterial infections and must be taken as prescribed by a doctor. One of the most frequently asked questions about antibiotics is: “Do antibiotics affect egg quality?” Antibiotic use can negatively affect egg quality. Therefore, they should not be used unnecessarily.
However, if your doctor deems it medically necessary, you should not avoid taking antibiotics. When used correctly, antibiotics can treat infections that pose a serious barrier to pregnancy and thus strengthen the reproductive system. In this sense, they may actually make it easier to become pregnant.
Does a Woman’s Age Affect Egg Quality?
As women age, both the number and quality of their eggs decline. Egg quality particularly begins to drop after age 35. Because of poor egg quality in their 40s, women may find it difficult to conceive, even with IVF treatment.
That said, egg quality is not the same for every woman in the same age range. One woman may experience low egg quality at a young age, while another may maintain high-quality egg reserves until a more advanced age. If you wish to have a baby in the future and are concerned about your age, you may consider egg freezing after consulting your doctor.
Does Being Overweight Affect Egg Quality?
As mentioned earlier, being overweight—especially obesity—negatively affects egg quality. Women who are significantly overweight have a lower chance of becoming pregnant compared to those with a healthy weight, due to poor egg quality. Excess weight can also reduce the success rate of IVF treatment.
Therefore, if you are planning a healthy pregnancy, it is very important to lose excess weight under the guidance of a specialist dietitian.
Can You Get Pregnant with Poor-Quality Eggs?
Many women who plan pregnancy and are concerned about their current egg quality wonder: “Are there women who get pregnant with poor-quality eggs?” Becoming pregnant with poor-quality eggs is very difficult. Even if pregnancy occurs, low-quality eggs will form low-quality embryos.
In such cases, the embryo may fail to implant in the uterus, or even if it does, it may not be able to remain attached, resulting in miscarriage. For all these reasons, if you are worried about your egg quality, you should see a doctor before attempting pregnancy or experiencing failed fertilization.
How Can Egg Quality Be Improved?
We mentioned that egg quality is influenced by environmental and genetic factors. Certain lifestyle changes and practices can increase egg quality and improve the chance of pregnancy. Let’s now take a look at the things that may help improve egg quality.
Which Exercises Improve Egg Quality?
Regular exercise can improve blood circulation, which in turn can help regulate the menstrual cycle, enhance egg quality, and support fertility. Exercise also strengthens the immune system and supports mental well-being, helping you feel better overall during the process of improving egg quality.
Some exercises you can do include:
- Walking
- Light cycling
- Tai Chi
- Swimming
You can also incorporate specific yoga poses to support egg quality:
- Balasana (Child’s Pose): Helps you feel emotionally calm and relaxed.
- Supta Baddha Konasana (Reclining Bound Angle Pose): Enhances blood flow in the pelvic area.
- Viparita Karani (Legs-Up-the-Wall Pose): Can help regulate the endocrine system.
- Setu Bandha Sarvangasana (Bridge Pose): Supports stimulation of the ovaries.
- Additionally, you can include practices such as Nadi Shodhana Pranayama, Bhujangasana, Kapalbhati Pranayama, and Yoni Mudra in your yoga routine. It is also helpful to integrate breathing exercises while practicing yoga.
Which Foods Improve Egg Quality?
The foods you consume affect your hormones, cellular processes, and reproductive system. Nutrition is directly linked to egg quality. Women can develop certain dietary habits to support healthy ovulation.
Eat Antioxidant-Rich Foods
Foods rich in antioxidants are among the most important for improving egg quality. Antioxidants fight oxidative stress (the imbalance between free radicals and antioxidants), which can reduce egg quality.
Vitamin C is one of the most powerful antioxidants. You can add the following foods to your daily diet:
- Broccoli
- Oranges
- Mandarins
- Peppers
- Cabbage and Brussels sprouts
- Cauliflower
- Pineapple
- Kiwi

- Hazelnuts
- Peanuts
Beta-carotene, a powerful precursor of vitamin A, is also highly beneficial for eggs. Foods rich in beta-carotene that may help boost egg production include:
- Melon
- Carrots
- Sweet potatoes
- Squash
Include Omega-3 Fatty Acids in Your Diet
You can increase your chances of developing healthy eggs by ensuring adequate intake of omega-3 fatty acids, which regulate hormones and have anti-inflammatory properties. Some foods rich in omega-3 include:
- Flaxseed oil
- Canola oil
- Chia seeds
- Soybeans
- Salmon
- Sardines
- Anchovies
- Tuna
- Shellfish such as oysters, lobster, and scallops
- Walnuts
Consume Folate-Rich Foods
Folate, a form of vitamin B9, plays an important role in egg quality and maturation. Foods that contain folate and may help improve egg quality include:
- Lentils
- Peas
- Asparagus
- Green leafy vegetables
- Beets
- Liver
- Bananas
- Papaya
In addition, you can choose complex carbohydrates instead of simple carbohydrates, and include healthy fats such as olive oil and avocado oil in your daily diet. Try to create balanced meals in terms of all essential nutrients.
