in Singapore
Understanding Egg Freezing
Egg freezing, also known as elective egg freezing or oocyte cryopreservation, is a fertility preservation treatment that allows eggs to be collected and frozen for potential future use.
Some women consider egg freezing because they are not ready to conceive at the moment. In Singapore, elective egg freezing is available for women aged 21 to 37, regardless of marital status. Under current regulations, however, the frozen eggs may only be used for assisted reproduction after the woman is legally married.
Others may wish to understand their options earlier, before fertility naturally declines with age or before undergoing medical treatment that may affect fertility.
Who May Consider Egg Freezing?
Women who may consider egg freezing include those who:
Are not ready to conceive at this stage of life
Wish to preserve future fertility options
Have concerns about age-related fertility decline
Are planning medical treatment that may affect fertility
Are seeking more information before deciding on family planning
The decision should always be considered within the context of individual goals, age, fertility health, and future plans.
Why Timing Matters
in Egg Freezing
Female fertility naturally declines with age.
Over time, both the number and quality of eggs generally decline. As a result, timing can influence the number of eggs available for collection, their quality at the time of freezing and their potential future use.
Eggs frozen at a younger age are also generally less likely to have age-related chromosomal abnormalities, including those associated with conditions such as Down syndrome.
However, egg freezing does not remove the health considerations associated with becoming pregnant later in life.
How Dr Chua Helps Patients Decide
Dr Chua’s approach is to help patients have a clearer understanding of the options available.
- ● Their current fertility health
- ● What egg freezing can and cannot achieve
- ● How age may influence future fertility options
- ● The practical considerations involved
- ● Whether treatment aligns with their goals
The aim of an egg freezing consultation is not to rush the decision, but to help patients make informed choices with confidence and have greater flexibility when planning for the future.
The Egg Freezing Process
The first consultation focuses on understanding your situation clearly.
Step 1: Consultation and Fertility Assessment
The process begins with a consultation to understand your fertility health, medical history, and goals.
Assessment may include:
- Fertility history review
- Pelvic ultrasound
- Ovarian reserve assessment
- Relevant blood tests
This helps determine whether egg freezing may be appropriate and what to expect from treatment.
Step 2: Ovarian Stimulation – 10 to 12 days
Hormone injections are used to stimulate the ovaries so that multiple eggs can mature during the same treatment cycle.
During this period, ultrasound scans and monitoring appointments are used to track progress of the follicles and guide treatment timing.
Step 3: Trigger Injection
When the follicles have developed sufficiently, a trigger injection is given to help the eggs complete their final stage of maturation before collection.
The timing of this step is important and is planned carefully based on the monitoring results.
Step 4: Egg Retrieval
Egg retrieval is performed as a day procedure.
A fine needle is used to collect the mature eggs from the ovaries, and the eggs are then passed to the laboratory.
Step 5: Freezing and Storage
Suitable mature eggs are frozen using a rapid-freezing method known as vitrification and stored for potential future use.
The eggs remain frozen until they are needed, subject to prevailing regulations and storage arrangements.
Important Things
to Consider
Egg freezing can be a valuable option for some women, but it is important to understand both its benefits and limitations.
Egg freezing does not guarantee future pregnancy.
Future outcomes depend on many factors.
Two of the most important are:
- Age at the time of egg freezing
- Number of mature eggs frozen
Not every frozen egg will survive warming, fertilise or develop into an embryo. This is why the expected benefits and limitations should be discussed with a fertility specialist before deciding whether to proceed.
