Leading clinics like Superior A.R.T. and Jetanin Institute are well-regarded for their success in treating various fertility challenges and can be a good starting point.

2. Consider Preimplantation Genetic Testing (PGT)

PGT is a genetic screening technique that checks embryos for chromosomal abnormalities before implantation. This can reduce the risk of miscarriage and improve live birth rates, especially for patients with recurrent pregnancy loss or advanced maternal age.

• PGT-A (Aneuploidy Screening): Useful for patients over 35, this test screens embryos for chromosomal abnormalities, helping to select the healthiest embryos.
• PGT-M (Monogenic/Single Gene Testing): For couples with a history of genetic disorders, PGT-M can help prevent the transmission of specific genetic conditions.
• PGT-SR (Structural Rearrangements): Suitable for patients with known chromosomal structural rearrangements.

Clinics with PGT capabilities, like Superior A.R.T., often see improved success rates, particularly in patients with genetic concerns.

3. Opt for Blastocyst Transfer

Transferring embryos at the blastocyst stage (Day 5) rather than the cleavage stage (Day 3) allows for a better assessment of embryo quality, as only the strongest embryos survive to the blastocyst stage.

• Higher Implantation Rates: Blastocysts have a higher implantation potential, which increases the likelihood of a successful pregnancy.
• Lower Risk of Multiple Births: Single blastocyst transfer reduces the risk of twins or triplets while maintaining high success rates.

Most top clinics in Thailand, such as Bangkok Hospital IVF Center, offer blastocyst culture as part of their standard IVF packages.

4. Choose Individualized IVF Protocols

The choice of an IVF protocol impacts egg quality, embryo development, and overall IVF success. Experienced fertility specialists will customize protocols based on a patient’s age, ovarian reserve, and previous IVF response.

• Ovarian Stimulation Protocol: Tailoring stimulation protocols to each patient’s response improves the chances of retrieving quality eggs.
• Hormonal Support for Implantation: Adjusting hormonal support based on uterine lining health can improve implantation rates.
• Use of Mini-IVF for Older Patients: For some patients, mild stimulation protocols (Mini-IVF) may provide better-quality eggs and embryos.

Jetanin Institute is known for its customized IVF protocols, particularly for complex cases like low ovarian reserve or previous IVF failures.

5. Consider Intracytoplasmic Sperm Injection (ICSI) for Male Factor Infertility

For couples with male factor infertility, ICSI can greatly improve fertilization rates. ICSI involves injecting a single sperm directly into an egg, bypassing issues like low sperm count or poor motility.

• Improved Fertilization Rates: ICSI can improve the likelihood of fertilization, especially for patients with severe male infertility.
• Higher Pregnancy Rates: By ensuring successful fertilization, ICSI increases the chances of having viable embryos for transfer.

Clinics like Safe Fertility Center in Bangkok specialize in male infertility treatments, offering high success rates for couples who may otherwise struggle to achieve fertilization with standard IVF.

6. Optimize Lifestyle and Nutrition for IVF Success

Lifestyle factors, including diet, exercise, and stress management, play an important role in fertility and IVF outcomes. Making adjustments to improve overall health can increase the chances of success.

• Dietary Changes: A diet rich in antioxidants, vitamins, and minerals supports egg and sperm health. Include leafy greens, berries, nuts, lean protein, and omega-3s in your diet.
• Maintain a Healthy Weight: Both underweight and overweight individuals can experience reduced fertility, so maintaining a healthy BMI is ideal for IVF success.
• Avoid Alcohol, Caffeine, and Smoking: These substances can negatively affect fertility and reduce IVF success rates. Aim to eliminate or minimize them before and during IVF treatment.

Most IVF clinics in Thailand offer nutrition counseling and may recommend lifestyle adjustments to enhance fertility.

7. Reduce Stress with Mind-Body Practices

IVF can be emotionally and physically demanding, and high stress levels can negatively impact treatment outcomes. Incorporating stress management techniques can improve overall health and readiness for IVF.

• Mind-Body Therapies: Techniques like yoga, meditation, and deep breathing exercises can reduce stress and enhance relaxation.
• Acupuncture: Some studies suggest that acupuncture before and after embryo transfer can improve blood flow to the uterus, supporting embryo implantation.
• Counseling and Support Groups: Participating in counseling or support groups can help manage stress and foster a positive mindset during IVF treatment.

Many top IVF clinics in Thailand, including BNH Hospital, offer counseling and alternative therapies like acupuncture to support patients through the IVF process.

8. Opt for Single Embryo Transfer (SET) When Possible

Although transferring multiple embryos can increase pregnancy chances, it also raises the risk of multiple births, which can lead to complications. Clinics now recommend single embryo transfer (SET) to maximize success rates while minimizing risks.

• High Success Rates with Blastocyst Transfer: Transferring a single blastocyst offers a high chance of pregnancy without the risks associated with twins or triplets.
• Personalized Approach: Clinics will assess the best approach based on patient age, embryo quality, and previous IVF history.

Leading clinics in Thailand, such as Superior A.R.T. and Jetanin Institute, prioritize SET for safety and success.

9. Utilize Egg or Sperm Donation if Recommended

For patients with low ovarian reserve, poor egg quality, or severe male infertility, using donor eggs or sperm can significantly improve IVF success rates.

• Egg Donation for Older Women: Donor eggs from a younger, healthy donor offer higher success rates for older women or those with diminished ovarian reserve.
• Sperm Donation for Severe Male Infertility: Donor sperm can be a viable option when male infertility is a significant issue.

Most top clinics in Thailand, such as Bangkok Hospital IVF Center, offer comprehensive egg and sperm donation programs to support patients with fertility challenges.
