Understanding Egg Freezing

Posted on

What is Egg Freezing?

Egg freezing, medically termed oocyte cryopreservation, is a cutting-edge technique designed to preserve a woman’s fertility. The process comprises several steps:

  1. Ovary Stimulation: Hormonal injections are administered to stimulate the ovaries to produce multiple eggs.
  2. Egg Retrieval: Once mature, the eggs are carefully retrieved from the ovaries using a minor surgical procedure.
  3. Freezing: Post-retrieval, the eggs are swiftly frozen using a process called vitrification, a rapid freezing method that prevents ice crystal formation.
  4. Storage: These vitrified eggs are stored in a specialised laboratory under optimal conditions until the woman decides to use them.
  5. Thawing and Fertilisation: When ready for pregnancy, the eggs are thawed and then fertilised with sperm in the lab before being implanted in the uterus.

Who is Egg Freezing Suitable For?

  • Age considerations: Women in their late 20s to early 30s who wish to delay childbearing for various reasons.
  • Medical treatments: Those preparing for treatments like chemotherapy which might impact fertility.
  • Fertility concerns: Women with conditions such as polycystic ovary syndrome (PCOS) or a family history of early menopause.
  • Other personal reasons: Those who, for various personal reasons, feel they're not ready for parenthood but might wish to pursue it in the future.

Optimising Your Chances of Success

Success in egg freezing is not solely dependent on the procedure itself but also on overall health and lifestyle choices. Let's delve deeper into ways to optimise success:


Nutritional intake plays a crucial role in reproductive health and the quality of eggs. Here are specific dietary choices that can enhance success:

  • Antioxidant-rich foods: Combat oxidative stress and improve cellular health with blueberries, strawberries, and dark chocolate.
  • High protein and low carbs: A diet focusing on lean proteins and minimising simple carbs can be linked to improved egg quality.
  • Healthy fats: Support hormone production, including oestrogen, with avocados, nuts, and olive oil.
  • Whole grains: Stabilise blood sugar levels essential for reproductive health with quinoa, oats, and brown rice.


Supplementing can cover potential nutritional gaps:

  • Folate: This bioavailable form of folic acid is essential for DNA replication and supports healthy eggs.
  • Omega-3 (DHA and EPA): With a significant portion of the UK population deficient in omega-3, these fatty acids are vital for enhancing cell membrane health and egg quality.
  • CoQ10: This compound has shown potential in improving egg quality and overall fertility in various studies.
  • Vitamin D: Directly linked to reproductive health, it also promotes overall well-being.


Adopting certain lifestyle habits can significantly influence fertility and the success of egg freezing:

  • Manage stress: Chronic stress can impact hormonal balance. Engage in meditation, yoga, or even nature walks to keep stress at bay.
  • Maintain a healthy weight: Both extremes of the weight spectrum can impact fertility. A balanced weight supports optimal hormonal function and egg quality.
  • Avoid smoking and limit alcohol: Both habits can detrimentally impact fertility and egg quality. Aim for moderation or complete avoidance when preparing for egg freezing.
  • Regular exercise: Physical activity boosts circulation and overall health, both of which can enhance fertility. Aim for a mix of cardiovascular and strength training exercises.

While egg freezing provides an avenue for future fertility, maximising success involves a holistic approach. By making informed choices in diet, supplementation, and lifestyle, you can greatly enhance the quality of your eggs and the potential outcomes of the procedure.

Always consult with a fertility specialist when considering egg freezing or making decisions related to your reproductive health.
