IVF Pre-Treatment Checklist: 10 Essential Tests and How to Interpret Your Results
Key Takeaways: Thorough pre-treatment testing is the foundation of a successful IVF cycle. AddBaby Medical & Fertility Center has synthesized 15 years of experience across 5,000+ cases into a definitive pre-IVF checklist. These 10 tests — spanning female hormone levels, ovarian reserve, uterine assessment, male semen quality, and genetic screening — provide the critical data your medical team needs to design a protocol that gives you the best chance of success.
Quick Reference
| Factor | Details |
|---|---|
| Who this is for | Couples or individuals preparing to begin IVF treatment |
| Total core tests | 10 essential investigations |
| Best timing | Day 2–3 of menstrual cycle for hormonal tests; others are flexible |
| From first test to cycle start | Approximately 4–6 weeks |
| Validity of home-country tests | Most accepted in Thailand; some may need to be repeated at the clinic |
Why Thorough Testing Saves Time and Money
Many patients want to start IVF as quickly as possible, viewing pre-treatment testing as a formality or a delay. This is a costly misconception.
Here is why comprehensive testing matters in practical terms:
1. Identifies Correctable Factors That Affect Success Rates
For example, subclinical hypothyroidism (slightly elevated TSH) is a common and under-diagnosed cause of recurrent miscarriage and IVF failure — but it is easily corrected with medication. Identifying and treating it before starting a cycle can significantly improve outcomes. Missing it risks a failed cycle costing tens of thousands of dollars.
2. Enables Personalized Stimulation Protocol Design
AMH values and antral follicle count (AFC) are the core inputs for designing your ovarian stimulation protocol. Low-reserve patients need gentle stimulation protocols; high-responders (such as those with PCOS) require careful management to prevent ovarian hyperstimulation syndrome (OHSS). Without this data, your physician cannot create a precise, individualized plan.
3. Identifies Male Factor Issues Requiring Special Approaches
If sperm DNA fragmentation is elevated, standard IVF may be insufficient. ICSI (intracytoplasmic sperm injection) or testicular sperm extraction (TESE) may be required. Knowing this in advance prevents the expense and disappointment of a cycle destined to underperform.
4. Allows Precise Timing of Your Thailand Travel
Understanding your test results allows AddBaby's coordination team to help you plan your Thailand travel window with precision, minimizing unnecessary trips.
The 10 Essential Tests in Detail
Section I: Female Baseline Hormone Tests (Day 2–3 of Menstrual Cycle)
These three tests must be performed on Day 2–3 of a natural menstrual cycle (no hormonal injections within the preceding cycle) because hormone levels fluctuate throughout the cycle and are only diagnostically meaningful in their baseline state.
Test 1: AMH (Anti-Mullerian Hormone) — The Core Ovarian Reserve Marker
What Is AMH?
AMH is secreted by pre-antral and small antral follicles in the ovaries. Its blood concentration directly reflects the size of the remaining follicular pool and is currently the single most accurate marker of ovarian reserve.
Reference Ranges and Clinical Significance
| AMH (ng/mL) | Ovarian Reserve Assessment | IVF Implication |
|---|---|---|
| > 4.0 | Abundant (monitor for PCOS risk) | May require lower stimulation doses; OHSS prevention priority |
| 1.0 – 4.0 | Normal range | Standard stimulation protocol |
| 0.5 – 1.0 | Low reserve | Individualized protocol; expected lower egg yield |
| < 0.5 | Very low reserve | Evaluate donor egg option |
Important Note: AMH is not cycle-dependent and can be tested at any time. Testing on Day 2–3 is typically done for convenience alongside other hormonal panels.
AddBaby Recommendation: Patients with AMH below 1.0 ng/mL should contact our medical team promptly to evaluate whether protocol adjustments are needed (such as egg banking as an interim strategy).
Test 2: Baseline FSH, LH, and E2 (Follicle-Stimulating Hormone, Luteinizing Hormone, Estradiol)
Reference Ranges (Day 2–3 of Cycle)
| Hormone | Normal Reference Range | Abnormal Signals |
|---|---|---|
| FSH | 3–10 mIU/mL | > 15 mIU/mL suggests diminished ovarian reserve |
| LH | 1–10 mIU/mL | LH/FSH ratio > 2 suggests PCOS |
| E2 (Estradiol) | < 60 pg/mL | Elevated E2 can mask true FSH elevation |
Note: FSH and E2 must be interpreted together. In some patients with diminished ovarian reserve, compensatory E2 elevation suppresses FSH to artificially "normal" levels. Always interpret alongside AMH and AFC for a complete picture.
Test 3: Thyroid Function (TSH, Free T3, Free T4)
Thyroid disorders are extremely common among women of reproductive age and are frequently asymptomatic. Thyroid dysfunction is significantly associated with:
- Reduced egg quality
- Implantation failure
- Early pregnancy loss (particularly subclinical hypothyroidism)
- Pregnancy complications including preterm birth
Fertility-Specific Thyroid Targets
The general population TSH reference range is 0.4–4.5 mIU/L. However, most reproductive medicine guidelines recommend keeping TSH below 2.5 mIU/L for patients preparing for IVF, and below 1.5 mIU/L for patients with positive thyroid antibodies (anti-TPO).
If TSH is elevated: Low-dose levothyroxine typically normalizes TSH within 3–6 weeks — this can be addressed without meaningfully delaying your IVF cycle start.
Section II: Female Imaging Assessments
Test 4: Transvaginal Ultrasound — Antral Follicle Count (AFC)
What Is AFC?
AFC is the count of small follicles (2–10 mm in diameter) visible in both ovaries on transvaginal ultrasound. It represents the current number of "workable" follicles available for IVF stimulation.
Reference Ranges and IVF Implications
| Total AFC (Both Ovaries) | Expected Egg Yield | Protocol Strategy |
|---|---|---|
| > 15 | High (PCOS: monitor for OHSS risk) | Gentle protocol with close monitoring |
| 7 – 15 | Normal range | Standard stimulation protocol |
| 4 – 6 | Low reserve | Mini-stimulation or antagonist protocol |
| < 4 | Very low reserve | Evaluate donor egg necessity |
AFC should always be interpreted alongside AMH — only when both are consistently low can diminished ovarian reserve be confidently diagnosed.
Test 5: Uterine Assessment — Hysteroscopy or Hysterosalpingography (HSG)
Uterine cavity morphology and tubal patency significantly affect IVF outcomes, even when embryo transfer bypasses the fallopian tubes.
Hysteroscopy Advantages
- Direct visualization of the uterine cavity
- Simultaneous treatment of endometrial polyps, intrauterine adhesions, or uterine septa
- Recommended for patients with recurrent pregnancy loss or prior uterine procedures
HSG Advantages
- Lower cost; no anesthesia required
- Simultaneously assesses tubal patency (relevant because hydrosalpinx — fluid-filled fallopian tubes — can be embryo-toxic)
Critical Note: Even for IVF patients who don't need patent tubes for conception, hydrosalpinx should be treated before embryo transfer. Fluid from the hydrosalpinx can reflux into the uterine cavity and significantly impair implantation.
Section III: Infectious Disease Screening (Both Partners)
Test 6: Infectious Disease Panel (Hepatitis B, Hepatitis C, Syphilis, HIV)
These four tests are mandatory requirements at all assisted reproduction facilities, for three reasons:
- Laboratory safety: Samples from HBV-positive patients require handling in designated isolated areas to prevent cross-contamination
- Patient health protection: Some infections can be transmitted vertically (mother to baby) and require prophylactic intervention
- Thai legal compliance: Thai medical institutions are legally required to confirm these results before treatment
Validity Period: Results are typically valid for 6 months. Tests older than 6 months may need to be repeated at the Thai clinic.
Test 7: TORCH Panel
TORCH screens for four groups of pathogens:
- Toxoplasma gondii
- Rubella virus
- Cytomegalovirus (CMV)
- Herpes simplex virus
These infections are typically asymptomatic in healthy adults, but primary infection during early pregnancy can cause serious fetal abnormalities or miscarriage. Testing IgG and IgM antibodies reveals whether you have prior protective immunity (IgG positive, IgM negative — generally reassuring) or active/recent infection (IgM positive — requires management before proceeding with pregnancy attempts).
Section IV: Male Partner Tests
Test 8: Semen Analysis (WHO 2021 Standards)
Semen analysis is the foundational assessment of male fertility potential. Use WHO 6th Edition (2021) reference values:
| Parameter | WHO 2021 Lower Reference Limit |
|---|---|
| Sperm concentration | ≥ 16 × 10⁶/mL |
| Total motility (PR + NP) | ≥ 42% |
| Progressive motility (PR) | ≥ 30% |
| Normal morphology (Strict criteria) | ≥ 4% |
| Semen volume | ≥ 1.4 mL |
Collection Requirements: 2–7 days of sexual abstinence before collection (3–4 days is optimal). If the first result is abnormal, repeat the test 2–4 weeks later to rule out transient factors (recent high fever, acute illness, unusual stress, heat exposure).
If Severely Abnormal (Severe Oligospermia or Azoospermia): Proceed to evaluate testosterone, FSH, LH, prolactin, and karyotype analysis. ICSI or surgical sperm retrieval (TESE) may be indicated. Discuss options with our team at our contact page.
Test 9: Sperm DNA Fragmentation Index (DFI)
What Is Sperm DNA Fragmentation?
DNA strand breaks in sperm can impair embryo development after fertilization. Critically, DFI can be elevated even when routine semen analysis appears normal — making it an often-overlooked cause of unexplained IVF failure.
Reference Ranges and Clinical Decision-Making
| DFI (DNA Fragmentation Index) | Assessment | Management Strategy |
|---|---|---|
| < 15% | Normal | Standard IVF or ICSI |
| 15% – 30% | Moderately elevated | Prefer ICSI; lifestyle optimization for 3 months |
| > 30% | Significantly abnormal | Consider TESE; evaluate for varicocele repair |
Who Should Prioritize DFI Testing?
- Men with 2 or more prior IVF or embryo transfer failures
- Normal semen analysis but unexplained infertility over 12+ months
- Smoking history or occupational heat/chemical exposure
- Age above 45 years
Section V: Genetic Testing (When Indicated)
Test 10: Chromosomal Karyotype Analysis (Both Partners)
Strongly Recommended For
- Two or more unexplained miscarriages
- History of delivering a chromosomally abnormal child
- Known hereditary condition in the family (thalassemia, Fragile X syndrome, etc.)
- Severe oligospermia or azoospermia in the male partner (Y-chromosome microdeletion screening also recommended)
Karyotype results determine whether PGD (Preimplantation Genetic Diagnosis) should be incorporated into the IVF cycle to screen out chromosomally abnormal embryos before transfer. Learn about AddBaby's IVF-PGD services for personalized genetic screening options.
Testing Timeline and Planning
A realistic timeline from first test to IVF cycle start:
Weeks 1–2 (Day 2–3 of menstrual cycle):
- Hormonal panel: AMH, FSH, LH, E2, TSH
- Transvaginal ultrasound: AFC
- Infectious disease panel + TORCH
Weeks 2–3:
- Await results
- Begin treatment for any identified issues (e.g., thyroid medication, hydrosalpinx management)
- Male partner: Semen analysis + DFI (after 3–4 days abstinence)
Weeks 3–4:
- Hysteroscopy or HSG (Days 5–12 of cycle, after menstruation ends)
- Chromosomal karyotype analysis (if indicated)
- Consultation with AddBaby coordinator to review results and plan Thailand travel window
Weeks 5–6:
- Complete initial management of any abnormal findings
- Confirm Thailand dates and hospital appointment
- Begin pre-IVF medication protocols as directed
Testing in Your Home Country vs. Testing in Thailand
Complete at Home Before Traveling
- AMH and baseline hormonal panel (Day 2–3)

Frequently Asked Questions
Q1: Are test results from my home country valid for use in Thailand?
A: Most results are valid within their standard expiry windows. General guidelines: infectious disease panel — valid 6 months; hormonal panel — valid 3 months; semen analysis — valid 3 months (though some clinics prefer fresh results); AMH — not cycle-dependent, generally valid 6–12 months. Your AddBaby coordinator will review your reports and advise on whether any tests need to be repeated in Thailand.
Q2: My male partner cannot travel to Thailand. How can we manage semen-related needs?
A: Several options are available: (1) Complete semen analysis and DFI testing at home and bring the reports; (2) If sperm quality is good, cryopreserved sperm can potentially be transported to Thailand via specialized medical shipping services (confirm hospital acceptance policy in advance); (3) If the male partner has significant male factor infertility and cannot travel, evaluate donor sperm options through our services page. Contact us to discuss the approach that fits your specific situation.
Q3: Some of my test results are abnormal. Can I still do IVF?
A: In most cases, discovering abnormalities before starting a cycle is genuinely good news — because most issues can be addressed before the cycle begins, improving your chances of success. For example: elevated TSH can be corrected with medication; endometrial polyps can be removed by hysteroscopy; mild to moderate oligospermia can be managed with ICSI; high DNA fragmentation can be improved through lifestyle modifications or testicular sperm retrieval. Only a small proportion of findings — such as severely diminished ovarian reserve — require rethinking the fundamental treatment approach (e.g., donor eggs). Share your reports with AddBaby's medical team for a professional assessment.
Q4: My AMH is very low (below 0.5 ng/mL). Is it still worth trying IVF with my own eggs?
A: Low AMH does not necessarily mean zero chance. The right answer depends on your specific value, your age, AFC, and other factors. Some patients with AMH below 0.5 ng/mL still produce 1–3 eggs with modified stimulation protocols (mini-IVF or natural cycle IVF), sufficient for a transfer attempt. The critical advice: act promptly (ovarian reserve continues to decline with time) and choose a hospital with documented experience managing low-reserve patients. AddBaby's partner Jetanin Institute has a strong track record with diminished ovarian reserve cases. Book a consultation today for personalized guidance.
