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 Loh’s focus is IVF and assisted reproduction, and he is an accredited IVF specialist with experience that also spans advanced gynaecological surgery and high-risk obstetrics. Assisted reproduction brings together several techniques to help people having difficulty conceiving.
- In-vitro fertilisation (IVF): stimulating the ovaries to produce eggs, retrieving them, fertilising them in the laboratory and transferring an embryo to the womb.
- Frozen embryo transfer and related techniques: using embryos frozen in an earlier cycle, allowing flexible timing.
- Fertility preservation: approaches to preserve future fertility, an area on which he has published.
- Assessment of ovarian reserve and related factors: evaluating the factors that influence fertility, reflecting his published interests in ovarian reserve and endometriosis.
Treatment is tailored to the couple’s situation and history, drawing on a background that includes advanced gynaecological surgery where relevant, rather than following a single fixed path.
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 Loh will explain what the findings suggest, the options from simpler treatments through to IVF and frozen embryo transfer, the place of fertility preservation where relevant, 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 is fertility preservation?
It refers to approaches that aim to preserve the ability to have children in the future, such as freezing eggs or embryos, which may be relevant for medical or personal reasons.
What is ovarian reserve?
Ovarian reserve refers to the quantity of eggs remaining, which can be assessed with blood tests and ultrasound and helps inform fertility planning.
How many IVF cycles might be needed?
This varies between couples and depends on the underlying factors and how each cycle goes. Sometimes more than one cycle is needed, and realistic expectations, including the possibility that treatment may need to be repeated or adjusted, are discussed beforehand.
Can endometriosis affect fertility treatment?
Endometriosis can sometimes influence fertility and how treatment is planned, which is one reason a thorough assessment is part of the process. The plan is tailored to the factors identified in your case.
Do I need a referral?
No referral is strictly required at a private clinic, but bringing any letter and previous results helps the consultation and supports continuity of care.
