What is elective egg freezing?

Elective egg freezing refers to the process of cryopreserving a woman's eggs for future use when she is not currently facing medical reasons that may affect her fertility. It allows women to preserve their fertility potential by freezing eggs at a younger age for use in later years.

At what age should I freeze my eggs?

In general, the ideal age to consider egg freezing is before the age of 35. Fertility declines with age, and a woman's egg quality and quantity decrease significantly as she gets older. Freezing eggs at a younger age allows for the preservation of healthier and more viable eggs.

However, the decision to freeze eggs should be based on individual circumstances and discussions with a fertility specialist. Some women may choose to freeze their eggs in their late 20s or early 30s if they have concerns about their future fertility, while others may opt for egg freezing in their mid-30s or later.

It's important to note that the success of egg freezing and subsequent use of frozen eggs for pregnancy largely depends on the quality and quantity of the eggs at the time of freezing. Freezing eggs at a younger age generally results in better outcomes, but it does not guarantee a future pregnancy.

Consulting with your doctor is crucial to assess your specific fertility status, discuss the best timing for egg freezing based on your individual circumstances, and understand the potential success rates and limitations associated with the procedure. They can provide personalised guidance and help you make informed decisions regarding egg freezing.

When can I access my frozen eggs?

The duration for which eggs can stay frozen depends on various factors, including the cryopreservation techniques used and the regulations of the specific fertility clinic. In Singapore, the current guidelines allow eggs to be stored for up to 10 years, subject to yearly renewals. However, it's important to note that laws and regulations regarding egg freezing may evolve, and it's best to consult with a fertility specialist for the most up-to-date information.

What is the procedure like to undergo elective egg freezing?

The procedure for elective egg freezing involves several steps. First, the woman undergoes ovarian stimulation with fertility medications to stimulate the ovaries to produce multiple eggs. This process usually takes around 10 to 14 days and requires regular monitoring through ultrasound examinations and blood tests.

Once the eggs have matured, a minor surgical procedure called egg retrieval is performed. It involves the insertion of a needle into the ovaries, guided by ultrasound, to aspirate the mature eggs. This procedure is typically done under sedation or anesthesia to ensure patient comfort.

After retrieval, the eggs are immediately cryopreserved using a process called vitrification. In this method, the eggs are rapidly frozen to minimise the formation of ice crystals and preserve their viability. They are then stored in specialised cryopreservation tanks at very low temperatures until they are ready to be used.

When the woman decides to use her frozen eggs, they are thawed and fertilised with sperm through a procedure called intracytoplasmic sperm injection (ICSI) or other appropriate methods. The resulting embryos are monitored for development, and one or more embryos may be transferred into the woman's uterus during a subsequent IVF cycle.

It's important to note that the specific details and protocols for elective egg freezing can vary among fertility clinics. It's recommended to consult with a fertility specialist in Singapore who can provide personalised guidance and information regarding the procedure, legal considerations, and any specific requirements mandated by Singapore law.
