Complete List of Medical Examinations Required Before IVF in Thailand and Precautions – Full Version
Opening: Real Consultation Scenario
Real Consultation Scenario Last month, a 38-year-old patient consulted us online. She was preparing to go to Thailand for IVF, and her first question was: “What exact tests do I need for IVF in Thailand? Should I do them locally or in Thailand?” This question seems simple, but it comes up repeatedly in actual consultations. Most people have a clear information gap regarding the test items, their validity, and the connection between tests and the treatment cycle.
Module A: Direct Answer to the Question1. Thailand IVF Medical Examination Checklist
For IVF in Thailand, the examinations required for both partners can be divided into three main categories: Basic Fertility Assessment, Infectious Disease Screening, and Genetic Testing. Below is a standardized checklist covering the requirements of most fertility centers:
Female Examination Items
| Test Item | Specific Indicator / Method | Description & Timing |
|---|---|---|
| AMH | Anti-Müllerian Hormone | Blood test any day of menstrual cycle; assesses ovarian reserve, valid for 6 months |
| Sex Hormone Panel (6) | FSH, LH, E2, P, T, PRL | Blood test on day 2–3 of menstruation; evaluates baseline ovarian status and endocrine levels |
| Transvaginal Ultrasound | Antral Follicle Count (AFC), endometrium, ovarian morphology | Performed on day 2–4 of menstruation; assesses follicle reserve and uterine environment |
| Thyroid Function | TSH, FT3, FT4, TPOAb | Blood test any time; TSH should ideally be below 2.5 mIU/L |
| Infectious Disease Screening | Hepatitis B, Hepatitis C, HIV, Syphilis, TORCH | Valid for 6 months; some hospitals require original test reports |
| Coagulation Profile + Complete Blood Count | PT, APTT, FIB, PLT, etc. | Basic safety screening, valid for 3–6 months |
| Chromosome Karyotype | Peripheral blood chromosome analysis | Valid for life; mandatory for those with recurrent miscarriage or family history of genetic disorders |
Male Examination Items
| Test Item | Specific Indicator / Method | Description & Timing |
|---|---|---|
| Semen Analysis | Density, motility, morphology, DNA fragmentation index | Abstinence for 3–7 days; valid for 3–6 months, DNA fragmentation index recommended |
| Infectious Disease Screening | Hepatitis B, Hepatitis C, HIV, Syphilis | Should be done simultaneously with the female partner, valid for 6 months |
| Chromosome Karyotype | Peripheral blood chromosome analysis | Valid for life; recommended for oligoasthenospermia, azoospermia, or recurrent miscarriage history |
| Complete Blood Count + Coagulation | Basic blood parameters | Routine safety screening, valid for 3–6 months |
Note: The above are the basic requirements of most fertility centers in Thailand. Some hospitals may additionally require hysteroscopy, endometrial biopsy, full immunological panel, or genetic counseling, depending on the attending physician's protocol. Test reports must be provided in bilingual Chinese-English version or English translation with the hospital's official stamp.
2. How Reproductive Specialists View These Tests
From a reproductive medicine perspective, the core purpose of testing is not just to "pass," but to assess success rates, develop personalized protocols, and mitigate risks. For example, the AMH level determines the starting dose of ovarian stimulation medication and the expected number of eggs retrieved; the semen DNA fragmentation index directly affects embryo chromosomal abnormality rates and miscarriage risk. Doctors need complete test data to determine:
- Whether the patient is suitable to proceed with an IVF cycle
- Which ovarian stimulation protocol to choose (long protocol, short protocol, antagonist protocol, etc.)
- Whether additional interventions are needed (e.g., endometrial preparation, sperm selection, PGT)
Without any key test, the doctor cannot provide an accurate cycle plan and may even cancel the cycle, resulting in both time and financial losses.
3. Differences in Examination Focus by Age Group
Age is the most critical variable affecting fertility, and the focus of examinations varies significantly by age group:
| Age Group | Examination Focus | Common Adjustments |
|---|---|---|
| ≤35 years | Basic fertility assessment (AMH + sex hormones + ultrasound) + semen analysis + infectious disease screening | If no abnormalities, can proceed directly to cycle; pay attention to sperm DNA fragmentation index |
| 36–40 years | AMH + sex hormones + antral follicle count + thyroid function + chromosome karyotype (optional) | If AMH is low, consider adding vitamin D and thyroid autoantibodies; consider PGT-A |
| ≥41 years | Comprehensive: AMH + sex hormones + AFC + chromosome + coagulation + immunology + hysteroscopy | If ovarian reserve is diminished, proceed to cycle as soon as possible; recommend preimplantation genetic screening |
| Male ≥45 years | Semen analysis + DNA fragmentation index + chromosome karyotype + infectious disease screening | If DNA fragmentation index is elevated, adjust lifestyle or use antioxidant therapy |
For advanced age (especially ≥40 years), diminished ovarian reserve and increased embryo aneuploidy rates are the main challenges. The purpose of testing is not just "can it be done," but "how to achieve a higher success rate."
Module G: Most Easily Overlooked Details4. Most Easily Overlooked Details
While assisting hundreds of families in organizing test reports, the following details are repeatedly overlooked but directly affect cycle progress:
- Differences in AMH Testing Standards: Different laboratories use different reagent platforms (e.g., Beckman, Roche, Antu), leading to variations in reference ranges. It is recommended to have comparisons done at the same hospital to avoid misinterpretation due to inconsistent standards.
- Abstinence Time for Semen Analysis: Abstinence of <3 days or >7 days can affect result stability. Strictly control it within 3–7 days, and the sample should be delivered for testing within 1 hour of collection.
- Validity of Infectious Disease Screening: Most Thai fertility centers require infectious disease reports to be within 6 months, and some hospitals shorten this to 3 months. If the report expires, retesting is required, delaying the cycle.
- Translation of Chromosome Karyotype Report: Some Thai hospitals do not accept Chinese reports from domestic labs; an English translation with the hospital's official stamp or notarization is mandatory.
- Timing of Hysteroscopy: For those with recurrent implantation failure or abnormal ultrasound findings of the endometrium, hysteroscopy should be completed 2–3 months before starting the cycle, not in the same month.
5. Most Common Pitfalls
Based on real case feedback, the following three pitfalls are the most common:
Pitfall 1: All test results are "normal" but repeated failure occurs
Many people believe that if all indicators are within the reference range, it means "no problem." However, ovarian response, sperm fertilization ability, and embryo developmental potential cannot be fully predicted by routine tests. For example, an AMH of 1.5 ng/mL is within the normal range, but for women over 35, it may indicate significantly diminished ovarian reserve. Doctors need to integrate age, AFC, and medical history for a comprehensive assessment.
Pitfall 2: Men only have a routine semen analysis, not DNA fragmentation index
A normal routine semen analysis does not guarantee intact sperm genetic material. When the DNA fragmentation index (DFI) is above 30%, even with normal sperm count and motility, it can significantly affect fertilization and blastocyst formation rates, increasing miscarriage risk. Some Thai hospitals list DFI as a mandatory test.
Pitfall 3: Arranging tests too late
Many people only think about getting tests done when they decide to go to Thailand, only to find that AMH has expired, chromosome reports take 3 weeks, or infectious disease screening needs retesting... This delays the entire cycle by 1–2 months. It is recommended to complete all tests at least 2 months in advance.
6. Actual Process from Testing to Starting the Cycle
A standard timeline is as follows:
| Time Point | Task | Notes |
|---|---|---|
| 3–4 months before planned cycle start | Complete chromosome karyotype (if needed), hysteroscopy, genetic counseling | Chromosome report takes 2–3 weeks; hysteroscopy requires appointment |
| 2–3 months before planned cycle start | Complete AMH, sex hormones, ultrasound, semen analysis, infectious disease screening, coagulation, complete blood count | All reports valid for 3–6 months; pay attention to the time window |
| 1 month before planned cycle start | Organize all reports → translation/notarization → send to Thai doctor for evaluation | Some hospitals require original documents to be sent; allow time for courier |
| Month of cycle start | Travel to Thailand on day 2–3 of menstruation for ultrasound + blood rechecks; confirm protocol and start stimulation | Some tests need to be repeated in Thailand (e.g., infectious disease screening, ultrasound) |
Throughout the process, the completeness and timeliness of test reports are key to starting the cycle on schedule. It is recommended to create a "Test Item Tracking Sheet" to check the status and validity of each item.
Module L: Interpretation of Key Indicators7. Interpretation of Key Test Indicators
Below are the most closely monitored indicators in Thailand IVF and their clinical significance:
AMH (Anti-Müllerian Hormone)
- >1.5 ng/mL: Normal ovarian reserve, expected good egg yield
- 0.8–1.5 ng/mL: Mildly diminished reserve, stimulation protocol may need adjustment
- <0.8 ng/mL: Significantly diminished reserve, likely fewer eggs retrieved; consider starting the cycle as soon as possible
Can I still do IVF in Thailand with low AMH? Yes. Low AMH does not mean no eggs at all, just that the number may be lower. Doctors may use mild stimulation or natural cycle protocols, combined with embryo culture techniques, to improve efficiency. The key factors are age and egg quality.
FSH / LH Ratio
- FSH <10 IU/L, FSH/LH <2: Normal ovarian response
- FSH 10–15 IU/L, FSH/LH >2: Indicates diminished ovarian reserve, potentially reduced response
- FSH >15 IU/L: High risk of poor ovarian response; individualized protocol needed
Semen DNA Fragmentation Index (DFI)
- DFI <15%: Excellent, minimal impact on fertilization and embryo development
- DFI 15–30%: Moderate, lifestyle improvement recommended before retesting
- DFI >30%: Significantly affects embryo quality and pregnancy outcomes; intervention needed
Reminder: The above reference values may vary depending on the laboratory and testing method. Thai reproductive specialists will provide a personalized assessment based on age, AMH, AFC, and medical history, rather than relying on a single number.
8. Frequently Asked Questions
Question 1: Do test results have an expiration date?
Yes. AMH and semen analysis are valid for 3–6 months; infectious disease screening (Hepatitis B, Hepatitis C, HIV, Syphilis) is valid for 6 months; chromosome karyotype is valid for life; hysteroscopy and ultrasound results are generally accepted for 3–6 months. Reports beyond the validity period need to be redone.
Question 2: Does the male partner have to go to Thailand for tests?
Not necessarily. Most tests (semen analysis, infectious disease screening, chromosome) can be done domestically, and the reports can be translated and provided to the Thai hospital. However, some Thai hospitals require the male partner to be present at the start of the cycle and provide a recent semen analysis report. Confirm with the attending physician.
Question 3: How far in advance should passports and visas be prepared?
Passports must be valid for more than 6 months. It is recommended to check passport validity 1–2 months in advance. IVF in Thailand typically uses a medical visa or visa on arrival. A medical visa requires an invitation letter from the hospital, and the processing time is about 7–14 working days. Check the specific requirements of the Thai embassy or consulate in China.
Question 4: Is pre-IVF preparation needed?
Based on test results, targeted preparation can be done. For example, if AMH is low, consider supplementing with Coenzyme Q10 or DHEA (under medical guidance); if semen DFI is high, quit smoking, avoid high-temperature environments, and supplement with antioxidants (Vitamin E, Zinc, Selenium). It is not recommended to take large amounts of supplements on your own; do so under the guidance of a doctor or nutritionist.
Question 5: What documents are needed for registration?
Identity cards and passports of both partners, marriage certificate (bilingual Chinese-English notarized), all original test reports and translations, visa, and hospital invitation letter. Some hospitals require a dual-authentication document for the marriage certificate; it is recommended to prepare this 3 months in advance.
Module: Special Situations (Naturally Integrated)9. Special Situations
The following situations require additional specialized evaluations beyond routine tests:
- Recurrent miscarriage (≥2 times): Add chromosome karyotype for both partners, full immunological panel (antiphospholipid antibodies, NK cells, blocking antibodies), hysteroscopy, endometrial genetic testing
- Previous IVF failure: Add endometrial receptivity analysis (ERA), semen DNA fragmentation index, embryo chromosome analysis (PGT-A)
- Family history of genetic disorders: Requires genetic counseling and gene testing to identify the pathogenic gene before formulating a PGT-M plan
- Thyroid dysfunction: If TSH >2.5 mIU/L, consult an endocrinologist to adjust to normal range before starting the cycle
