IVF Add-On Treatments in Thailand: Evidence, Costs and Questions to Ask

IVF add-on treatments in Thailand are optional laboratory or transfer techniques that sit outside a standard IVF cycle. Common examples include IMSI, PICSI, embryo glue and assisted hatching. They are usually quoted as separate line items, and prices vary between clinics and even between patients at the same clinic. Because no single add-on is guaranteed to improve your chance of a live birth for every diagnosis, the practical task is to understand what each add-on does, how it is priced, and which questions will make a quote comparable.

At a glance

• Add-ons are optional; they are not required for a standard IVF cycle.
• Each add-on may be charged per cycle, per embryo, per transfer or as a package.
• Evidence for add-ons ranges from promising in selected cases to unproven for general use.
• Ask for a written quote that separates core cycle costs from add-on costs.
• Ask whether the fee is refundable if the add-on cannot be performed.

What counts as an IVF add-on?

An add-on is any test, technique or medication added to a standard IVF cycle with the aim of improving outcomes. It may be offered before fertilisation, during embryo culture, at embryo transfer, or after transfer. Some add-ons are laboratory methods, such as IMSI or PICSI. Others are transfer techniques, such as embryo glue or assisted hatching. Some clinics also offer add-ons such as time-lapse imaging, endometrial scratch, or additional genetic screening; those are separate topics and are not covered in detail here.

The key distinction is between a core cycle and an optional extra. A core IVF cycle typically includes monitoring, egg collection, fertilisation, embryo culture and transfer. Add-ons are the items a clinic may list separately on your quotation.

IMSI and PICSI in Thailand

IMSI (intracytoplasmic morphologically selected sperm injection) and PICSI (physiological intracytoplasmic sperm injection) are sperm selection methods used before injection into an egg. Both aim to help the embryologist choose sperm that may be more likely to support normal fertilisation and embryo development.

IMSI uses high-magnification microscopy to examine sperm shape in more detail than standard ICSI. PICSI uses a gel that binds sperm with certain surface characteristics, allowing the embryologist to select sperm that bind to the gel.

These techniques are usually offered when there is a history of poor fertilisation, low sperm quality, or previous unsuccessful ICSI cycles. However, evidence that they improve live birth rates for all patients is limited. Some studies suggest possible benefit in selected groups, while others show no clear advantage. A clinic may recommend one or both, but the decision should be based on your specific history rather than a general promise.

When comparing IMSI PICSI Thailand quotes, ask whether the fee is per cycle or per egg collection, whether it applies to all eggs or only some, and whether it is charged even if no sperm are suitable for selection.

Embryo glue in Bangkok clinics

Embryo glue is a transfer medium containing a substance called hyaluronan. It is used during embryo transfer with the idea that it may help the embryo attach to the uterine lining. Some clinics offer it as a routine add-on; others reserve it for selected cases.

Evidence for embryo glue is mixed. Some reviews suggest a possible small improvement in live birth rates in certain groups, while other analyses find no clear benefit. It is generally considered low-risk, but it is not a guarantee of implantation.

When you ask about embryo glue at a Bangkok clinic, clarify whether the fee is per transfer, per embryo, or included in a package. Ask whether it is used for fresh and frozen transfers, and whether the clinic charges separately if the transfer is cancelled after preparation.

Assisted hatching in Thailand

Assisted hatching is a laboratory technique that creates a small opening in the outer layer of the embryo (the zona pellucida) before transfer. It is sometimes offered to help the embryo hatch and implant. It may be performed using a laser, a chemical solution, or a mechanical method.

Assisted hatching is more often discussed for older patients, for embryos with a thick zona, or after repeated implantation failure. Evidence for its benefit is not consistent across all groups. Some studies suggest possible benefit in selected cases, while others show no clear improvement in live birth rates.

When comparing assisted hatching Thailand quotes, ask whether the fee is per embryo or per cycle, whether it is applied to all embryos or only those transferred, and whether the clinic charges if the embryo does not survive the procedure.

How add-on costs are structured

Add-on pricing in Thailand is not standardised. A clinic may quote an add-on as a fixed fee, a percentage of the cycle cost, or part of a package. The same add-on may cost differently depending on whether it is performed on fresh or frozen embryos, how many embryos are involved, and whether it is combined with other add-ons.

Because no approved price data is available for this guide, the table below shows cost categories rather than figures. Use it to structure your own comparison.

Cost category	What to confirm
Core IVF cycle	What is included: monitoring, egg collection, fertilisation, culture, transfer, medications, storage.
Add-on fee	Is it per cycle, per embryo, per transfer, or a package? Is it charged if the add-on cannot be performed?
Medication	Are add-on-related medications included or billed separately?
Laboratory charges	Are there separate fees for embryology, micromanipulation, or extended culture?
Transfer charges	Is the transfer fee separate from the add-on fee?
Storage and freezing	Are there annual storage fees for remaining embryos?
Monitoring and visits	Are scan and blood test fees included or charged per visit?
Administration	Are there registration, coordination, or translation fees?

Ask for a written quotation that lists each item separately. A quote that only gives a total is difficult to compare with another clinic.

What may change the price

• Number of embryos treated: some add-ons are charged per embryo, so the total depends on how many embryos you have.
• Fresh versus frozen transfer: the fee may differ between the two.
• Cancelled or delayed cycles: ask whether add-on fees are refundable or transferable.
• Combination of add-ons: some clinics offer a discount for multiple add-ons; others charge each separately.
• Clinic location and setting: fees may vary between hospitals, standalone clinics and university-affiliated centres.
• Currency and payment method: exchange rates and international transaction fees may affect the final amount you pay.

Questions to ask a clinic

1. Which add-ons do you recommend for my specific history, and why?
2. What is the evidence for each add-on in patients like me?
3. Is the add-on fee per cycle, per embryo, or per transfer?
4. Is the fee refundable if the add-on cannot be performed or the cycle is cancelled?
5. Are there any additional laboratory or medication costs linked to the add-on?
6. How many embryos would be treated, and how does that affect the price?
7. Can you provide a written quote that separates core cycle costs from add-on costs?
8. What are the risks or uncertainties of each add-on?
9. If I decline the add-on, what is the expected outcome range for my age and diagnosis?
10. Are there any package options that include add-ons, and what are the conditions?

How to compare quotes

When you receive quotes from different clinics, place them side by side using the same categories. Check whether each quote includes medications, monitoring, laboratory work, transfer, and storage. Then list add-ons separately. A lower total may exclude items that another clinic includes, so compare the full picture rather than the headline number.

Also ask whether the clinic can provide outcome data for patients with your profile, and whether that data is internally audited. Be cautious of any clinic that guarantees a specific result or promises a fixed price without a written breakdown.

Next steps

• Write down your diagnosis, age, and previous IVF history.
• Ask your current clinic which add-ons, if any, are relevant to you.
• Request written quotes from two or three clinics using the same list of items.
• Review the evidence for each add-on with your doctor before deciding.
• Keep a copy of all quotes and correspondence for your records.

Frequently asked questions

Are IVF add-ons in Thailand included in the standard cycle price?

Usually not. Most clinics quote add-ons as separate line items. Ask for a written breakdown that shows the core cycle, each add-on, medications, laboratory work, and transfer fees so you can compare quotes accurately.

Does IMSI or PICSI improve the chance of pregnancy?

Evidence is mixed. Some studies suggest possible benefit in selected cases, such as previous poor fertilisation or certain sperm abnormalities, but not all patients benefit. Your clinic should explain why a specific add-on is being recommended for your situation.

Is embryo glue safe and effective?

Embryo glue is generally considered low-risk, but evidence for improved live birth rates is not consistent. It may be offered routinely or for selected cases. Ask your clinic about the expected benefit for your profile and how the fee is charged.

When is assisted hatching recommended?

Assisted hatching is sometimes discussed for older patients, embryos with a thick outer layer, or after repeated implantation failure. Evidence is not uniform, so it is best to ask your embryologist whether it is likely to help in your specific case.

Can I decline add-ons and still have a standard IVF cycle?

Yes. Add-ons are optional. You can ask your clinic to proceed with a standard cycle and to explain the expected outcome range for your age and diagnosis without the add-on.

How do I compare add-on prices between clinics?

Request a written quote from each clinic using the same list of items: core cycle, each add-on, medications, monitoring, laboratory work, transfer, and storage. Compare the full list rather than the total, and ask whether fees are refundable if a cycle is cancelled.
