I. Direct Answer: What Examinations Are Needed Before IVF in Thailand?

In reproductive clinics, we often see couples planning to go to Thailand for IVF, carrying a large stack of test reports for consultation. Their most pressing questions are: Are these tests sufficient? Will they be accepted in Thailand? Which ones need to be retaken?

The purpose of pre-treatment examinations for Thailand IVF is to assess whether the patient meets the medical conditions for IVF, while also identifying potential risks that could affect success rates or pregnancy safety. The examinations are divided into female and male parts, covering reproductive function assessment, genetic screening, infectious disease screening, and basic health status evaluation.

Module I: Actual Process

II. Examination Process and Order of Execution

Pre-treatment examinations do not need to be completed all at once; they can be done step by step according to the menstrual cycle and personal schedule.

• Step 1 (Menstrual Period): The female partner goes to the hospital on menstrual cycle day 2–4 for a blood draw to check the sex hormone panel (6 items) and a transvaginal ultrasound for antral follicle count. These two tests must be completed within this time window.
• Step 2 (Non-menstrual Period): The female partner undergoes vaginal discharge routine, cervical TCT, and urinalysis 3 days after menstruation ends. The male partner can simultaneously complete the semen analysis and blood draw items.
• Step 3 (Any Time): Both partners complete blood draw items such as AMH, thyroid function, infectious disease screening, chromosome karyotype analysis, CBC, and coagulation profile. These tests are not restricted by the menstrual cycle and can be done in one visit.
• Step 4 (If Necessary): If there is a history of uterine surgery, recurrent miscarriage, or ultrasound suggests uterine cavity abnormalities, a hysteroscopy is required. It is recommended to schedule it 3–7 days after menstruation ends.

The entire examination cycle usually takes 2–4 weeks, depending on the hospital schedule and the individual's menstrual cycle.

Module J: Timing

III. Examination Timeline and Result Validity

Timing is one of the most underestimated aspects of overseas IVF preparation. The validity periods of different examination results vary greatly; improper planning may lead to expired reports requiring retesting just before departure.

Examination Item	Result Validity	Recommended Completion Time
Infectious Disease Screening (Hepatitis B, Hepatitis C, HIV, Syphilis)	3 months	Complete within 2 months before departure
Chromosome Karyotype Analysis	Valid for life	Any time; recommended to complete as early as possible
Sex Hormone Panel (6 items) + Antral Follicle Count	3–6 months (varies with age and menstrual cycle)	Complete within 1–3 months before departure
AMH	6–12 months (for those with stable ovarian reserve)	Complete within 6 months before departure
Thyroid Function	3–6 months	Complete within 3 months before departure
Semen Analysis	3–6 months	Complete within 3 months before departure
CBC, Coagulation, TORCH	3–6 months	Complete within 3 months before departure

Module L: Interpretation of Key Indicators

IV. Interpretation of Key Examination Indicators

The following indicators are closely monitored by Thai reproductive specialists, as they directly influence treatment plan selection and success rate prediction.

AMH (Anti-Müllerian Hormone)

• Normal Range: 1.0–4.0 ng/mL (slight variations exist between different laboratories)
• Below 1.0 ng/mL: Indicates diminished ovarian reserve; the number of eggs retrieved during stimulation may be low, requiring a mild stimulation or natural cycle protocol.
• Above 4.0 ng/mL: Requires vigilance for Polycystic Ovary Syndrome (PCOS) tendency; monitor OHSS risk during stimulation.

FSH (Follicle-Stimulating Hormone)

• Normal Range: < 10 IU/L (on menstrual cycle day 2–4)
• 10–15 IU/L: Indicates diminished ovarian reserve; may require higher doses of stimulation medication.
• > 15 IU/L: Indicates significantly decreased ovarian reserve; requires combined assessment with AMH and AFC to predict egg yield.

TSH (Thyroid-Stimulating Hormone)

• Ideal Level: < 2.5 mIU/L
• 2.5–4.0 mIU/L: Considered subclinical hypothyroidism; some reproductive centers require it to be below 2.5 before starting a cycle.
• > 4.0 mIU/L: Requires endocrinology consultation; medication treatment to reach target before considering cycle initiation.

Key Semen Analysis Indicators

• Sperm Concentration: ≥ 15 × 10⁶ /mL
• Progressive Motility (PR): ≥ 32%
• Normal Morphology Rate: ≥ 4% (strict criteria)
• When the above indicators are significantly abnormal, additional testing for Sperm DNA Fragmentation Index (DFI) may be needed to assess sperm nuclear integrity.

Module G: Most Easily Overlooked Details

V. Most Easily Overlooked Examination Details

From clinical experience, the following examinations are often overlooked but have a direct impact on the Thailand IVF cycle.

• Thyroid Function: Many patients focus only on the sex hormone panel and AMH, neglecting TSH. TSH above 2.5 can affect embryo implantation rates, and Thai doctors usually require it to be below 2.5 before starting a cycle.
• Vitamin D Level: Although not mandatory, clinical data shows that Vitamin D deficiency is associated with decreased endometrial receptivity. If you work indoors long-term or have limited sun exposure, consider testing 25-hydroxyvitamin D.
• Blood Type and Rh Factor: If the female partner is Rh-negative, anti-D immunoglobulin prophylaxis is needed during pregnancy; inform the reproductive center in advance.
• Cervical TCT: Routine screening before pregnancy; if cervical lesions are found, they need to be treated before starting the cycle.
• Laboratory Accreditation for Infectious Disease Screening: Some Thai hospitals only accept reports from specific laboratories. Confirm the list of recognized testing facilities with the Thai hospital in advance to avoid report rejection.

Module H: Common Pitfalls

VI. Common Misconceptions and Pitfall Alerts

Misconception 1: The male partner doesn't need testing, or only needs a routine semen analysis

Male infectious disease screening and chromosome testing are equally important. If the male partner carries Hepatitis B or Syphilis, the Thai hospital needs to implement specific laboratory handling and embryo management measures. Structural abnormalities like balanced chromosomal translocations also affect the normal rate of embryonic chromosomes, requiring PGT screening at the embryo stage.

Misconception 2: Low AMH means no chance at all

Low AMH only indicates a reduced quantity of ovarian reserve, not necessarily poor quality. Clinically, patients with AMH 0.5–0.8 ng/mL can still achieve 1–3 high-quality embryos. The key is to develop an individualized stimulation protocol, such as using mild stimulation or natural cycles, rather than blindly pursuing follicle numbers.

Misconception 3: It's more convenient to do all tests in Thailand

Having tests done locally in Thailand can save the hassle of carrying reports, but the cost of medical examinations in Thai facilities is usually higher than in top-tier hospitals in China. Moreover, some tests (like chromosome karyotype analysis) take 2–4 weeks for results, prolonging the stay in Thailand. It is recommended to complete most basic tests in your home country, reserving only time-sensitive items (like menstrual phase hormones) for Thailand.

Misconception 4: Passport and visa preparation are not synchronized with examinations

Overseas IVF requires a passport valid for at least 6 months. If your passport is about to expire, renew it before arranging tests, as the name and ID number on the test reports must match the passport. Additionally, a Thai medical visa requires a hospital invitation letter and medical reports; some test reports are also used for visa applications and need to be photocopied and notarized in advance.

Module C: Doctor's Perspective

VII. Core Recommendations from Reproductive Specialists on Pre-treatment Examinations

From a clinical decision-making perspective, Thai reproductive specialists make three key judgments based on pre-treatment examination results:

• Whether the patient is suitable to start a cycle: If there is uncontrolled thyroid disease, active infectious disease, or endometrial pathology, the doctor will recommend treatment first before initiating the cycle.
• Which stimulation protocol to choose: Based on AMH, FSH, AFC, and age, patients are categorized into normal, low, and high ovarian response types, using antagonist, mild stimulation, or agonist protocols respectively.
• Whether Preimplantation Genetic Testing (PGT) is needed: If one partner has a chromosomal structural abnormality, a single gene disorder, or if the female is ≥ 38 years old or has a history of recurrent miscarriage, the doctor will recommend PGT-A or PGT-M.

Therefore, pre-treatment examinations are not just a "threshold to cross," but provide the basis for subsequent treatment decisions. The more complete and standardized the examinations, the more precise the doctor's treatment plan will be.

Module Q: Frequently Asked Questions

VIII. Frequently Asked Questions

Q1: Can the pre-treatment examinations for Thailand IVF be done in China?

Yes. The vast majority of examination items can be completed at a正规 top-tier hospital or reproductive center in China. However, note that some Thai hospitals require infectious disease screening reports from laboratories with ISO 15189 accreditation. It is advisable to confirm the report format and accepted list with the Thai hospital in advance. Chromosome karyotype analysis reports are generally recognized globally and do not need to be repeated.

Q2: If AMH is low, will the Thai doctor refuse treatment?

Generally, they will not refuse, but the doctor will fully inform you about the expected egg yield and the risk of cycle cancellation. When AMH is below 0.5 ng/mL, the doctor may recommend a natural cycle or mild stimulation protocol, retrieving 1–3 eggs per cycle, potentially requiring multiple stimulations to accumulate enough embryos. In such cases, both time and financial costs need to be assessed in advance.

Q3: What additional preparations are needed for advanced maternal age (≥40 years) undergoing Thailand IVF?

In addition to routine examinations, it is recommended to add the following assessments: ① Endometrial Receptivity Array (ERA) to rule out displaced implantation window; ② Hysteroscopy to rule out endometrial polyps, adhesions, or other space-occupying lesions; ③ Genetic counseling to assess the need for PGT-A; ④ Cardiovascular and metabolic function assessment, as the risk of pregnancy complications increases with advanced age.

Q4: How long are the test results valid?

Infectious disease screening (Hepatitis B, Hepatitis C, HIV, Syphilis) is valid for 3 months; sex hormone panel (6 items), AMH, thyroid function, and semen analysis are valid for 3–6 months; chromosome karyotype analysis is valid for life. It is recommended to start the examination process 2–3 months before your confirmed travel date to ensure all reports are within their validity period.

Q5: Is it necessary to optimize health before IVF in Thailand?

Yes. However, optimization is not just about taking supplements; it involves targeted adjustments based on test results. For example: Vitamin D deficiency requires Vitamin D 4000 IU/day; elevated TSH requires levothyroxine as prescribed; abnormal semen analysis requires investigation for varicocele or reproductive tract infections. Also, it is recommended to quit smoking, limit alcohol, maintain a regular sleep schedule, and for obese individuals (BMI ≥ 28), losing 5%–10% of body weight can improve the endocrine environment and embryo quality.
