At a glance
Understand how stimulation drugs, monitoring scans, and PGT timing shape your IVF medication schedule in Thailand, and what to confirm with your treating clinic.
If you are preparing for PGT IVF in Thailand, your medication protocol will be tailored to your ovarian response, your clinic’s laboratory schedule, and your travel plans. Most protocols involve ovarian stimulation drugs, monitoring scans and blood tests, a trigger injection, and a short course of medication after egg retrieval. The exact drugs, doses, and duration are individual medical decisions made by your treating clinic. This guide explains the general categories and questions to ask so you can plan with confidence.
At a glance
- Stimulation drugs are prescribed by your clinic based on your medical history and response.
- Monitoring scans and blood tests track follicle growth and hormone levels.
- PGT adds a biopsy and genetic testing step after egg retrieval, which can affect your overall timeline.
- Medication schedules are individual; confirm all details with your treating clinic.
- Travel planning should account for monitoring visits and possible schedule changes.
What is a PGT IVF medication protocol?
A PGT IVF medication protocol is the plan your clinic creates to stimulate your ovaries to produce multiple eggs in one cycle. It includes the types of medication, when to start them, how doses may be adjusted, and when to take a trigger injection before egg retrieval. Because PGT involves testing embryos after retrieval, the medication protocol itself is usually similar to a standard IVF cycle, but the overall timeline may be longer because of the biopsy and testing steps.
Protocols are not one-size-fits-all. Your clinic will consider your age, ovarian reserve, previous response to stimulation, and other health factors. International patients should expect the clinic to explain the rationale for your specific plan and to provide a written schedule.
Common categories of stimulation medication
Stimulation protocols generally use injectable gonadotropins to encourage follicle growth. Your clinic may also prescribe medication to prevent premature ovulation, and a trigger injection to prepare for egg retrieval. The table below outlines general categories; your clinic will decide which are appropriate for you.
| Medication category | General purpose | What to confirm with your clinic |
|---|---|---|
| Gonadotropins (FSH and/or LH) | Stimulate multiple follicles to grow | Exact drug, dose, start date, and injection technique |
| GnRH antagonist or agonist | Prevent premature ovulation | When to start, how to store, and side effects to report |
| Trigger injection (hCG or GnRH agonist) | Mature eggs for retrieval | Exact timing, as it is critical for retrieval scheduling |
| Post-retrieval medication | Support the luteal phase or prepare for transfer | Whether it is needed, for how long, and how it fits your travel plans |
This table is for general orientation only. It is not a prescription or a recommendation. Your clinic will provide a personalized medication plan.
Monitoring scans and blood tests
During stimulation, your clinic will monitor your response with ultrasound scans and blood tests. These visits typically happen every few days, and the frequency may increase as your follicles mature. Monitoring helps your clinic adjust medication doses and decide when to schedule the trigger injection and egg retrieval.
For international patients, monitoring can sometimes be arranged locally before travel, but this depends on your clinic’s policy and your home clinic’s willingness to collaborate. You should confirm whether your Thailand clinic accepts local monitoring results, what specific tests they require, and how they prefer to receive them. If monitoring must be done in Thailand, plan to stay near the clinic for the stimulation period.
How PGT timing affects your protocol length
PGT involves removing a few cells from each embryo (biopsy) and testing them for chromosomal or genetic conditions. This step happens after egg retrieval and fertilization, once embryos reach a certain stage. Because testing takes time, your clinic may freeze the embryos and plan a later transfer cycle. This means your overall timeline from stimulation to transfer can be longer than a standard IVF cycle without PGT.
The medication protocol for stimulation itself is usually not extended by PGT. However, you may need additional medication to prepare your uterus for a frozen embryo transfer (FET) if you and your clinic decide to transfer after testing. The exact timing depends on your clinic’s laboratory schedule and your individual plan.
Planning your travel around the protocol
International patients often need to coordinate travel with the stimulation schedule. Here are general planning categories to discuss with your clinic:
- Initial consultation: Can it be done remotely before travel? What tests are needed first?
- Stimulation start: When should you arrive in Thailand? Can you start medication in your home country?
- Monitoring: Will scans be done at the clinic in Thailand or locally? How often?
- Trigger and retrieval: How much notice will you get for the retrieval date? Is it flexible?
- Post-retrieval: When can you fly home? Do you need to stay for a transfer or can it be done later?
- PGT results: How will you receive results? What is the expected timeframe?
Because timelines can shift based on your response to medication, it is wise to build some flexibility into your travel plans. Ask your clinic about their typical schedule and any contingency plans.
Questions to ask your treating clinic
Before you commit to a protocol, make sure you understand the following. Write down the answers so you can refer to them later.
- What stimulation protocol do you recommend for me, and why?
- Which medications will I take, and what are their potential side effects?
- How will you monitor my response, and where should monitoring take place?
- How will PGT affect the timing of my retrieval and transfer?
- What is the expected total duration of the medication protocol?
- What costs are associated with medications, monitoring, and PGT?
- What happens if my response is slower or faster than expected?
- Can I start some medications in my home country?
- What support do you offer for international patients (e.g., coordination, translation)?
- What documents do I need to bring, and what are the visa or entry requirements?
These questions help you clarify the clinical plan and the practical logistics. They are not a substitute for personalized medical advice.

Frequently asked questions
How long does a PGT IVF medication protocol last in Thailand?
The stimulation phase typically lasts around 10 to 14 days, but this varies by individual and protocol. PGT adds time after retrieval for biopsy and testing, which may extend your overall timeline. Your clinic will provide a personalized estimate based on your response.
Can I start stimulation medication in my home country before traveling to Thailand?
Some clinics allow you to start certain medications locally, but this depends on your clinic's policy and your home clinic's cooperation. You should confirm with your treating clinic whether this is possible and how monitoring will be handled.
What monitoring is needed during stimulation for PGT IVF?
Monitoring usually involves ultrasound scans and blood tests to track follicle growth and hormone levels. The frequency varies, but it is typically every few days. Your clinic will tell you whether monitoring can be done locally or must be done in Thailand.
Does PGT change the medication protocol for stimulation?
The stimulation medication protocol itself is generally similar to standard IVF. However, because PGT involves testing embryos after retrieval, your clinic may recommend freezing all embryos and planning a later transfer cycle, which can involve additional medication.
What should I ask my clinic about medication costs and logistics?
Ask for a breakdown of medication costs, whether they are included in a package, and how prescriptions are handled for international patients. Also confirm how you will receive medications, how to store them, and what to do if you need dose adjustments.
