Getting to the clinic
Dr Tan Heng Hao practises at Virtus Fertility Centre Singapore, in the Orchard Road area, which is well served by public transport. He previously held senior roles at KK Women’s and Children’s Hospital, which is in the Novena area near Novena MRT, but his current practice is at Virtus.
- By MRT: The Orchard area is served by Orchard MRT (NS22 / TE14) and Somerset MRT (NS23), with the Thomson-East Coast Line also serving Orchard; from the stations it is a short, largely sheltered walk.
- By bus: Many services run along Orchard Road and connecting roads; check your specific route.
- By car or taxi: Taxis and ride-hailing can drop off close to the centre, and paid visitor parking is available in the Orchard buildings, though it can be busy at peak times.
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 IVF and assisted reproduction covers
Dr Tan’s focus is in-vitro fertilisation and assisted reproduction, and he is a Ministry of Health-accredited IVF specialist. Assisted reproduction brings together several techniques to help people having difficulty conceiving, with the approach guided by the underlying factors.
- In-vitro fertilisation (IVF): stimulating the ovaries to produce eggs, retrieving them, fertilising them in the laboratory and transferring an embryo to the womb.
- Intracytoplasmic sperm injection (ICSI): injecting a single sperm directly into an egg, often used where there are sperm-related factors.
- Frozen embryo transfer: transferring an embryo frozen in an earlier cycle, allowing flexible timing.
- Assessment of both partners: identifying the reasons for difficulty conceiving, which can involve either or both partners.
Treatment is tailored to the couple’s situation and history rather than following a single fixed path, and the assessment is about understanding the underlying factors before choosing an approach.
What to expect at a consultation
A first visit typically begins with a detailed history from both partners where applicable: how long you have been trying, menstrual and reproductive history, previous pregnancies or treatments, general health and lifestyle. Investigations are commonly arranged, which may include blood tests to assess hormones and ovarian reserve, an ultrasound scan, and a semen analysis for the male partner.
Dr Tan will explain what the findings suggest, the options from simpler treatments through to IVF, ICSI or frozen embryo transfer, and the realistic expectations, benefits and limits of each, so that decisions are made together and well informed.
Preparing for your appointment
- Photo identification and any GP or polyclinic referral letter.
- Records of previous fertility tests, treatments, scans or surgery, for both partners where relevant.
- A note of your menstrual cycle pattern and any recent ovulation tracking.
- A list of current medicines and supplements for both partners.
- A written list of questions and concerns; attending together as a couple, where applicable, is often helpful.
If you have had recent blood tests, scans or a semen analysis, bringing the actual results can save repeating them and help the discussion.
After your consultation and follow-up
After the assessment you should understand the likely factors involved and the options. If treatment such as IVF is planned, the clinic will explain the steps of a cycle, the monitoring involved and what to expect, including that more than one cycle is sometimes needed. Results of investigations are discussed at review, and the plan can be adjusted as you go. Continuity of care matters in fertility treatment, and you are free to take time, to discuss decisions as a couple, and to seek a second opinion before proceeding. Seek prompt medical advice if, during treatment, 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. Government co-funding and the use of MediSave for assisted reproduction may apply for eligible couples within set limits and conditions, while other costs are generally paid out of pocket. As eligibility varies, confirm current fees, co-funding and what applies to your situation directly with the clinic.
Common questions
What does it mean to be an MOH-accredited IVF specialist?
It means the doctor is recognised under Singapore’s regulatory framework to provide assisted reproduction services. The clinic can confirm current accreditation details.
What is the difference between IVF and ICSI?
In IVF, eggs and sperm are combined in the laboratory. In ICSI, a single sperm is injected directly into an egg, often used where there are sperm-related factors.
How many cycles might be needed?
This varies between couples and depends on the underlying factors. Sometimes more than one cycle is needed, and your specialist will discuss realistic expectations.
Should both partners attend?
Where applicable, attending together is often helpful, since factors can involve either or both partners and decisions are usually made as a couple.
What lifestyle factors can affect fertility?
General health, weight, smoking and other lifestyle factors can influence fertility for both partners, and these are commonly discussed at the consultation as part of an overall plan alongside any specific treatment.
