Learn about common pre-IVF tests including hormone panels, ultrasound, semen analysis, and genetic screening, and why they are important before starting treatment in Thailand.
Understanding Pre-IVF Testing
Before starting an IVF cycle, your fertility specialist will recommend a series of tests to assess your reproductive health and identify any factors that may affect treatment success. These tests help tailor your treatment plan and ensure you are physically ready for the procedures ahead. While specific requirements vary by clinic and individual health profile, the following categories are commonly included.
Common Pre-IVF Tests
Hormone Panel
A blood test to measure key reproductive hormones is typically one of the first steps. This panel often includes:
- Follicle-stimulating hormone (FSH) – helps evaluate ovarian reserve
- Luteinizing hormone (LH) – important for ovulation assessment
- Estradiol (E2) – indicates ovarian function
- Anti-Müllerian hormone (AMH) – a key marker of ovarian reserve
- Progesterone – checks ovulation and luteal phase
- Prolactin – high levels can affect fertility
- Thyroid-stimulating hormone (TSH) – thyroid imbalances can impact conception
These tests are usually done on specific days of your menstrual cycle. Your clinic will advise the optimal timing.
Ultrasound Examination
A transvaginal ultrasound is used to visualize the ovaries, uterus, and endometrium. It can detect:
- Ovarian cysts or fibroids
- Uterine abnormalities (e.g., polyps, adhesions)
- Endometrial thickness and pattern
- Antral follicle count (AFC) – another measure of ovarian reserve
This scan is often performed early in the cycle and may be repeated during stimulation.
Semen Analysis
For male partners, a semen analysis evaluates sperm count, motility, morphology, and other parameters. This test is essential to determine if intracytoplasmic sperm injection (ICSI) or other techniques may be needed. Some clinics require abstinence of 2–5 days before the sample is provided.
Genetic Screening
Carrier screening for genetic conditions may be recommended, especially if there is a known family history or for certain ethnic groups. Common tests include cystic fibrosis, spinal muscular atrophy, and thalassemia. Preimplantation genetic testing (PGT) of embryos may also be discussed, but this is typically a separate decision made after initial testing.
Infectious Disease Screening
Blood tests for HIV, hepatitis B and C, syphilis, and other infections are standard to protect both the patient and the embryo. These are often required by Thai regulations and clinic protocols.
Other Tests
Depending on your age, medical history, and previous fertility treatments, your doctor may order additional tests such as:
- Hysterosalpingography (HSG) to check fallopian tube patency
- Hysteroscopy to examine the uterine cavity
- Endometrial biopsy or receptivity array
- Vitamin D levels or other nutritional assessments
How to Prepare for Pre-IVF Testing
Preparation steps vary by test. For blood work, you may need to fast or avoid certain medications. Ultrasound appointments often require a full bladder. Semen analysis typically requires abstinence. Always follow your clinic’s specific instructions. It is also wise to bring any previous medical records, including past fertility test results, to your consultation.
Questions to Ask Your Clinic
Before undergoing testing, clarify the following with your chosen fertility center:
- Which specific tests are included in the initial workup?
- Are there any additional tests recommended based on my age or history?
- What is the timeline from testing to starting the IVF cycle?
- Do I need to repeat any tests if they were done recently elsewhere?
- Are there any dietary or medication restrictions before testing?
Next Steps
Once your test results are reviewed, your fertility specialist will discuss a personalized treatment plan. This may include adjusting medications, scheduling the IVF cycle, or recommending additional procedures. Remember that pre-IVF testing is a routine part of the process and helps maximize your chances of a successful outcome.
Frequently asked questions
How long does pre-IVF testing take?
Most tests can be completed within one menstrual cycle, but some results (like genetic screening) may take a few weeks. Your clinic will provide a timeline based on your specific tests.
Do I need to repeat tests if I had them done in my home country?
Many clinics accept recent results (usually within 6–12 months), but they may require certain tests to be repeated for accuracy or regulatory reasons. Always check with your clinic beforehand.
Are pre-IVF tests covered by insurance?
Coverage varies widely. Check with your insurance provider and the clinic about costs. Some clinics offer package deals that include initial testing.
Can I do all tests in one day?
Some tests can be done on the same day, but others (like hormone panels) need to be timed with your cycle. Your clinic will schedule them accordingly.
What if a test result is abnormal?
An abnormal result does not necessarily mean you cannot proceed with IVF. Your doctor will explain the implications and may recommend additional treatments or adjustments to your protocol.
