Learn why a frozen embryo transfer (FET) may be cancelled in Thailand, what refund policies typically cover, and how to plan your next steps with your clinic.
Understanding FET Cancellation
A frozen embryo transfer (FET) cycle may be cancelled before the scheduled transfer for various medical reasons. While this can be disappointing, it is a standard part of IVF care to ensure the best chance of success and safety. In Thailand, clinics follow international protocols, and cancellation decisions are made by your fertility specialist based on your individual response.
Common Reasons for Cancellation
Thin Endometrial Lining
The uterine lining must reach an adequate thickness (typically measured by ultrasound) to support implantation. If the lining does not thicken sufficiently despite medication, the cycle may be cancelled to avoid a low chance of pregnancy.
Hormonal Imbalances
FET cycles rely on precise hormone levels (estrogen and progesterone). If levels are not optimal on the planned transfer day, your doctor may cancel and adjust the protocol for a future cycle.
Ovarian Cysts or Other Findings
Unexpected ovarian cysts, fluid in the uterus, or other ultrasound findings can interfere with implantation. Cancellation allows time for these issues to resolve.
Poor Embryo Quality After Thaw
Although rare, some embryos may not survive the thawing process or may show reduced quality. If no suitable embryo remains, the cycle is cancelled.
What to Expect After Cancellation
Your clinic will explain the specific reason and discuss next steps. Typically, you will stop medications as directed and wait for your next menstrual period to begin a new cycle. The timeline for a repeat FET depends on your individual situation and clinic protocol.
Refund Policies and Financial Considerations
Refund policies vary by clinic and package. Some clinics offer partial or full refunds for cancelled cycles, while others may credit the amount toward a future cycle. It is essential to review your treatment agreement carefully before starting. Ask your clinic:
- What is the refund policy if my FET is cancelled?
- Are medication costs refundable?
- Will there be additional charges for monitoring in a cancelled cycle?
- Can I transfer my payment to a future cycle?
Travel and Accommodation Planning
If you are traveling to Thailand for FET, cancellation can affect your stay. Consider booking flexible flights and accommodation. Discuss with your clinic how long you may need to remain in Thailand if a cancellation occurs, and whether monitoring can be done remotely for a future cycle.
Next Steps Checklist
- Confirm the reason for cancellation with your doctor.
- Review your clinic’s refund or credit policy.
- Ask about the recommended waiting period before a new FET.
- Discuss any adjustments to your medication protocol.
- Update your travel plans if needed.
- Seek emotional support if you feel disappointed.
Questions to Ask Your Clinic
- What specific criteria determine whether my FET is cancelled?
- How will I be notified of a cancellation decision?
- What are my options if my lining is thin?
- Can I use the same embryo in a future cycle?
- What is the success rate for FET after a cancelled cycle?
Remember, a cancelled FET is not a failure—it is a precaution to optimize your chances. Always verify details directly with your treating clinic, as policies and medical practices can vary.
Frequently asked questions
Can I get a refund if my FET is cancelled in Thailand?
Refund policies depend on your clinic and treatment package. Some clinics offer partial or full refunds for cancelled cycles, while others may credit the amount toward a future cycle. Always review your agreement before starting treatment.
How long do I have to wait after a cancelled FET to try again?
The waiting period varies. Most clinics recommend waiting for one natural menstrual cycle before starting a new FET protocol. Your doctor will advise based on your individual situation.
What happens to my frozen embryos if the transfer is cancelled?
Your embryos remain frozen at the clinic. They can be used in a future FET cycle once the reason for cancellation is resolved. You may need to pay ongoing storage fees.
Is a cancelled FET common?
Cancellation rates vary, but it is not uncommon. Thin lining or hormonal issues are frequent reasons. Your clinic can provide data on their own cancellation rates if you ask.
Can I travel home immediately after a cancelled FET?
Yes, once your doctor confirms it is safe. You may need to stop medications and have a follow-up ultrasound. Discuss travel timing with your clinic.
