Ways to enhance egg quality

Egg quality plays a critical role in fertility and pregnancy outcomes. Thanks to the expertise of Dr. Serap Kağan, the Medical Director of Cyprus IVF Hospital, this article delves into understanding the factors influencing egg quality. This knowledge should empower individuals and couples to take proactive steps towards optimizing their fertility health, thereby increasing their chances of realizing their dream of parenthood naturally or by undergoing IVF treatment with own oocytes. From the structural integrity of eggs to environmental influences and lifestyle choices, Dr. Kagan’s insights shed light on the complexities of egg quality and offer guidance on enhancing fertility prospects.

What is Egg Quality?

Egg quality refers to the health and viability of a woman’s eggs, also known as oocytes. It encompasses various factors, including the structural integrity of the egg, its chromosomal makeup, and its ability to fertilize and develop into a healthy embryo. Egg quality plays a pivotal role in the process of conception, influencing embryo quality, fertilization rates, and the success of implantation. Various factors, including age, genetics, environmental exposures (like stress and smoking), lifestyle choices, nutrition, and the use of supplements, contribute to egg quality.

How Egg Quality Affects Fertility

  1. Fertilization: The quality of the egg directly impacts the fertilization process. High-quality eggs are more likely to be successfully fertilized by sperm, leading to the formation of viable embryos.
  2. Embryo Development: After fertilization, the quality of the egg continues to play a crucial role in embryo development. High-quality eggs have the potential to develop into healthy embryos capable of implanting in the uterine lining and progressing into a successful pregnancy.
  3. Implantation: Eggs with poor quality may result in embryos with chromosomal abnormalities or developmental defects, reducing the likelihood of successful implantation in the uterus.
  4. Miscarriage Risk: Poor egg quality is associated with an increased risk of miscarriage, as embryos with chromosomal abnormalities are more likely to fail to implant properly or result in early pregnancy loss.

While factors such as age and genetics play a significant role in fertility, there are proactive steps that can be taken to support reproductive health and enhance fertility potential through the diet and strategic use of supplements.

Enhancing Egg Quality through Diet and Use of Supplements

As individuals prepare for the egg retrieval process, focusing on nutrition becomes essential for supporting overall reproductive health and optimizing egg quality. Research indicates that dietary habits significantly impact egg quality and subsequently affect the success rate of fertilization. A balanced intake of protein, carbohydrates, fats, vitamins, and minerals is crucial. Vitamins and minerals are particularly important for safeguarding cells against toxins through their antioxidant properties. Including a diverse range of fruits and vegetables—such as peppers, berries, beetroots, carrots, and sweet potatoes — can maximize nutrient and antioxidant intake. Protein-rich foods like eggs, lean meats, nuts, and seeds aid in the body’s repair and maintenance processes. Carbohydrates and healthy fats, such as sweet potatoes, brown rice, quinoa, oats, asparagus, spinach, chia seeds, olive oil, and avocado, provide essential fiber, hormonal balance, and sustained energy levels.

Supplements are also a valuable tool in promoting overall health and well-being, and their role in fertility optimization is increasingly recognized.

Although no specific medications are proven to increase egg reserve, certain supportive treatments, like supplement intake, aim to enhance egg quality and mitigate cellular aging. These supplements work by providing essential nutrients, antioxidants, and other compounds that support reproductive function, improve egg quality, and enhance the chances of conception.

It’s important to note that while supplements may offer support, there’s no guarantee that they will increase egg quality, as genetic and age-related factors also play significant roles. Nonetheless, some supplements may contribute to overall reproductive health.

Q10 to improve egg quality

Here are some supplements that have been linked to promoting reproductive wellness:

  • Coenzyme Q10 (CoQ10): This antioxidant has been linked to enhancing egg quality and fertility by safeguarding eggs against oxidative damage.
  • DHEA (Dehydroepiandrosterone): Secreted by the adrenal glands, DHEA supplementation is contemplated for individuals facing challenges like diminished ovarian reserve or poor egg quality. It aims to enhance egg quality and slow down the decline in ovarian function.
  • Folic Acid (Folate): Vital for healthy cell division, folic acid is crucial in reducing the risk of certain birth defects. It’s commonly advised for women embarking on conception journeys and during early pregnancy.
  • Inositol: Particularly Myo-inositol, this compound is gaining attention for its potential to improve egg quality and ovarian function. It may also increase the likelihood of conception, particularly in individuals with conditions like polycystic ovary syndrome (PCOS).
  • Vitamin D: Adequate levels of vitamin D play a pivotal role in reproductive health by regulating menstrual cycles and enhancing fertility.
  • Vitamin E: Serving as an antioxidant, vitamin E shields cells, including eggs, from oxidative damage. Maintaining optimal antioxidant levels is essential for reproductive well-being, with adherence to recommended dosages being imperative.
  • Resveratrol: Found in red grapes and certain plants, resveratrol possesses antioxidant properties that may positively impact reproductive health.
  • NAC (N-acetyl cysteine): This antioxidant aids in replenishing glutathione, a critical antioxidant in the body, potentially benefiting reproductive health.
  • Selenium: Integral to antioxidant defense mechanisms, selenium is vital for reproductive health. Maintaining appropriate levels is crucial, as deficiency can negatively impact fertility, while excess intake should be avoided.
  • Zinc: Essential for DNA synthesis and cellular division, zinc is indispensable for reproductive health. Striking a balance is key, as excessive intake can have adverse effects.
  • Omega-3: Derived from fish oil supplements, omega-3 fatty acids contribute to hormone regulation and support healthy ovarian function, thereby promoting reproductive vitality.

Remember that the effectiveness of these supplements can vary from person to person, and their impact on egg quality may not be significant. Along with supplementary intake, focus on adopting a healthy lifestyle, which entails maintaining a balanced diet, engaging in regular physical activity, managing stress effectively, and refraining from smoking and excessive alcohol consumption. These lifestyle factors can have a significant impact on fertility and reproductive health.

It is essential to take the supplements with the recommended dosages under the supervision of an expert fertility doctor before proceeding with the egg retrieval process.

Broadening the Approach: Lifestyle Factors Beyond Diet and Supplements

While diet and supplements play crucial roles in enhancing egg quality and overall fertility, adopting a holistic approach that includes broader lifestyle factors is essential. Making positive changes in several aspects of daily life can significantly impact reproductive health. Here are key lifestyle factors to consider:

  • Physical Activity: Regular, moderate exercise can improve fertility by boosting overall health, reducing stress, and helping to maintain a healthy weight. Activities like walking, yoga, and swimming are beneficial, but it’s important to avoid overly strenuous exercises which can negatively impact fertility.
  • Stress Management: Chronic stress can affect hormonal balance and fertility. Incorporating stress-reduction techniques such as mindfulness, meditation, deep breathing exercises, or gentle yoga can help manage stress levels, promoting a more fertile environment for egg production and quality.
  • Sleep Quality: Adequate, restful sleep is vital for fertility. Poor sleep can disrupt hormones essential for reproduction. Aim for 7-9 hours of quality sleep per night and maintain a regular sleep schedule to support hormonal balance and reproductive health.
  • Avoiding Environmental Toxins: Exposure to certain environmental toxins can harm reproductive health. Reduce exposure by choosing organic foods when possible, using natural cleaning and beauty products, avoiding plastics with BPA, and steering clear of areas with high pollution levels.
  • Limiting Caffeine and Alcohol: Excessive intake of caffeine and alcohol can impair fertility. Limiting caffeine to less than 200 mg per day (about one 12-ounce cup of coffee) and reducing alcohol consumption can have positive effects on egg quality and fertility.
  • Smoking Cessation: Smoking has been linked to reduced fertility and poorer egg quality. Quitting smoking is one of the most effective steps women can take to improve their reproductive health.
  • Maintaining a Healthy Weight: Being underweight or overweight can affect hormone production and inhibit ovulation. Maintaining a healthy weight through balanced nutrition and regular physical activity can enhance fertility.
  • Mind-Body Therapies: Techniques such as acupuncture, fertility massage, and guided imagery can complement traditional approaches to fertility by reducing stress and enhancing blood flow to reproductive organs.

Dr. Serap Kağan says “Incorporating these lifestyle changes can create a supportive environment for improving egg quality and enhancing fertility. It’s important to remember that these changes should be made gradually and in consultation with healthcare providers to ensure they align with your individual health needs and fertility goals.”
