When couples are considering In Vitro Fertilization (IVF), several necessary tests must be performed by experts to gather information about the patients' fertility status and determine the most suitable treatment methods. Undergoing these assessments before the treatment begins ensures that the clinical team can tailor a protocol specifically to your biological needs, maximizing the potential for a positive outcome.
Common tests performed before IVF treatment in Turkey include blood tests, imaging tests, ovarian reserve assessments, and semen analysis. Istanbul has become a global hub for these diagnostic procedures, offering state-of-the-art laboratory technology alongside experienced fertility specialists.
Hormonal and Blood Health Screening
Before IVF treatment, your doctor needs to understand the hormonal environment of both partners. Extensive blood work provides a roadmap for the ovarian stimulation phase, helping doctors determine the correct dosage of medications.
Key Hormones Evaluated
- FSH (Follicle-Stimulating Hormone): Measured early in the menstrual cycle to assess how hard the body is working to produce eggs.
- AMH (Anti-Müllerian Hormone): A critical marker that indicates the remaining egg supply.
- Estradiol: An estrogen hormone that helps evaluate the health of the follicles.
- LH (Luteinizing Hormone): Vital for understanding the ovulation cycle.
- TSH & Prolactin: Thyroid function and prolactin levels can significantly impact reproductive health if they are imbalanced.
In addition to hormones, blood group identification and a complete blood count (CBC) are standard parts of the initial screening process.
Ovarian Reserve Testing
Ovarian reserve testing examines the quality and quantity of a woman's eggs. While no test can definitively predict a pregnancy, these results help the medical team manage expectations and adjust stimulation protocols. Analyzing your blood test results—specifically AMH—alongside an Antral Follicle Count (AFC) performed via ultrasound helps your doctor visualize your ovarian capacity.
Tubal Patency and Uterine Evaluation
Before beginning IVF, doctors must confirm the health of the uterine environment. This is often done through a Hysterosalpingogram (HSG), or "tubal patency test." This imaging technique uses a specialized dye to determine if the fallopian tubes are open and to check the shape of the uterine cavity. While IVF bypasses the fallopian tubes, identifying issues like hydrosalpinx (fluid-filled tubes) is crucial because such conditions can interfere with embryo implantation.
Infectious Disease Screening
Ensuring the safety of the patients, the future child, and the laboratory environment is a priority. Infectious disease screening is a mandatory step in IVF. Both partners will be tested for:
- HIV and Hepatitis B & C
- Syphilis and other STIs
- Rubella (German Measles) and Varicella (Chickenpox) immunity for the woman
- Chlamydia
Semen Analysis for Male Fertility
The male factor contributes to approximately 40-50% of infertility cases. The semen is analyzed to determine sperm count (concentration), motility (movement), and morphology (size and shape). If the semen analysis reveals severe abnormalities, specialized procedures like Micro-TESE or ICSI (Intracytoplasmic Sperm Injection) may be recommended to improve fertilization chances.
The Importance of Diagnostic Accuracy in Istanbul
Patients traveling to Istanbul for IVF benefit from a centralized diagnostic approach. Most initial tests can be completed within a single visit, allowing for a rapid transition into the treatment phase. These tests allow clinicians to identify underlying issues—such as polyps, fibroids, or hormonal imbalances—that might have prevented natural conception in the past.
Initial IVF Tests FAQ
How long do these tests take to complete?
Most blood tests and semen analyses provide results within 24 to 48 hours. However, some specific hormonal or genetic tests may take up to a week. If you are traveling to Turkey, your coordinator will help schedule these so they can be reviewed during your first consultation.
When in my cycle should these tests be performed?
Hormonal tests like FSH and Estradiol are typically measured on Day 2 or 3 of your menstrual cycle. Other tests, such as the AMH or infectious disease screenings, can be performed at any time during the month.
What if my test results are not ideal?
Ideal results are not a requirement for starting IVF; rather, these tests act as a guide. If a low ovarian reserve or a sperm issue is detected, your specialist will adjust the medication protocol or suggest advanced laboratory techniques to optimize the chances of success based on your specific profile.
