Getting to the clinic

Dr Jessie Phoon practises at STO+G Practice. She previously directed the KKIVF Centre and the National Sperm Bank at KK Women’s and Children’s Hospital, which is in the Novena area, but her current practice is at STO+G Practice. As the building is not separately listed here, plan your journey using public transport to the practice’s stated location.

• By MRT and bus: The practice is served by nearby MRT and bus routes; check the specific station and bus services for the clinic’s address before you travel.
• By car or taxi: Taxi and ride-hailing drop-off is available at the building. Many private medical centres have paid visitor carparks, so allow a little time to park if you are driving.

Fertility care often involves a series of visits over a cycle, some early in the morning for monitoring, so it helps to plan a routine that fits your travel and your day.

What egg freezing and fertility preservation covers

Dr Phoon’s focus is egg freezing and fertility preservation, alongside assisted reproductive techniques and minimally invasive gynaecological surgery. Fertility preservation aims to keep open the possibility of having children in the future.

• Egg freezing: stimulating the ovaries, retrieving eggs and freezing them for potential future use, whether for medical reasons or personal planning.
• Fertility preservation: the broader set of approaches to protect future fertility, including before treatments that may affect it.
• Assisted reproductive techniques: including in-vitro maturation (IVM), an approach within assisted reproduction, as part of the wider range of fertility treatment.
• Minimally invasive gynaecological surgery: keyhole techniques to diagnose and treat gynaecological conditions with smaller incisions.

Egg freezing and fertility preservation decisions are personal and time-sensitive, and the assessment is about understanding your circumstances, your reproductive plans and the relevant factors so that the approach fits your situation.

What to expect at a consultation

A first visit usually begins with a detailed history: your menstrual and reproductive history, general health, any medical conditions or planned treatments that may affect fertility, and your future plans. Investigations are commonly arranged, which may include blood tests to assess hormones and ovarian reserve and an ultrasound scan of the ovaries, helping to estimate what an egg-freezing cycle might involve.

Dr Phoon will explain what the findings suggest, what egg freezing or other fertility-preservation options involve, the realistic expectations and the benefits and limits, so that any decision is informed and made at your own pace.

Preparing for your appointment

• Photo identification and any GP or polyclinic referral letter.
• Records of previous fertility tests, scans or gynaecological treatment.
• A note of your menstrual cycle pattern and any recent tracking.
• A list of current medicines and supplements.
• A written list of questions, including your thoughts on timing and future plans.

If you have had recent blood tests or ultrasound scans, bringing the actual results can save repeating them and help the discussion.

After your consultation and follow-up

After the assessment you should understand your ovarian reserve picture and the options. If an egg-freezing or fertility-preservation cycle is planned, the clinic will explain the steps, the monitoring involved and what to expect, including that the number of eggs retrieved varies between individuals. Frozen eggs are stored for potential future use, and the practical and time-related aspects of storage will be explained. You are free to take time to consider, and to seek a second opinion before proceeding. Seek prompt medical advice if, during or after a stimulation cycle, you develop severe abdominal pain, marked bloating, breathlessness or significant discomfort, which should be assessed without delay.

Booking, referrals and fees

At a private clinic an appointment can usually be arranged without a referral, though a referral letter and previous records help with continuity and may be relevant for subsidies in the public system. The use of MediSave for assisted reproduction and any applicable co-funding may apply for eligible individuals within set limits and conditions, while other costs, including elective egg freezing and ongoing storage, are generally paid out of pocket. As eligibility and storage arrangements vary, confirm current fees and what applies to your situation directly with the clinic.

Common questions

Who might consider egg freezing?

People may consider it for medical reasons, such as before treatments that could affect fertility, or for personal planning. An assessment helps clarify whether and when it is appropriate.

How many eggs are collected?

The number varies between individuals and depends on factors such as ovarian reserve and the response to stimulation. Your specialist will discuss realistic expectations.

What is in-vitro maturation (IVM)?

IVM is an approach within assisted reproduction in which eggs are matured in the laboratory. Whether it is suitable depends on your individual circumstances.

How long can frozen eggs be stored?

Storage is subject to practical arrangements and the applicable rules in force at the time; the clinic can explain the current storage terms, any renewal requirements and what they mean for you, so you can plan ahead with a clear understanding.

Does egg freezing guarantee a future pregnancy?

No. Egg freezing aims to preserve the option of using those eggs later, but it does not guarantee a pregnancy, as outcomes depend on the number and quality of eggs and other factors. Your specialist will discuss realistic expectations for your situation.
