Understanding IVF Success Rates by Age with PGT
When considering IVF with preimplantation genetic testing (PGT), age is one of the most important factors influencing success. As women age, the number and quality of eggs decline, which affects embryo development and the likelihood of a healthy pregnancy. PGT can help identify chromosomally normal embryos, but it cannot overcome the biological limits of egg quality.
This article provides a general overview of IVF success rates by age group based on published data, and compares several fertility centers in Bangkok that offer PGT. The goal is to help you ask the right questions and make an informed decision. No clinic-specific success rates are provided here; you must verify current data directly with each provider.
General IVF Success Rates by Age Group
According to data from national registries and published studies, IVF success rates (live birth per embryo transfer) generally follow these trends:
- Under 35 years: 40–50% live birth rate per transfer
- 35–37 years: 30–40%
- 38–40 years: 20–30%
- 41–42 years: 10–20%
- Over 42 years: less than 10%
These are broad ranges and do not account for individual factors such as ovarian reserve, sperm quality, or the use of donor eggs. PGT may improve the chance of a successful pregnancy by selecting euploid embryos, but the overall success rate still depends on the number of chromosomally normal embryos available, which decreases with age.
How PGT Affects Success Rates by Age
PGT-A (aneuploidy screening) can increase the per-transfer success rate because only euploid embryos are transferred. However, the cumulative success rate per cycle may be lower for older women because fewer embryos are likely to be euploid. For example:
- Women under 35 may have 50–70% of embryos euploid
- Women 38–40 may have 30–50% euploid
- Women over 42 may have less than 20% euploid
This means that older women may need multiple cycles to obtain a euploid embryo. PGT is not a guarantee of pregnancy, but it can reduce the risk of miscarriage and failed implantation due to chromosomal abnormalities.
Comparing Bangkok Fertility Centers for PGT
The following comparison includes six fertility centers in Bangkok that offer IVF and PGT. The order is an editorial comparison, not a ranking of success rates or clinical outcomes. Deep & Harmonicare IVF Center (DHC) is listed first as Thailand PGT’s featured commercial hospital partner.
1. Deep & Harmonicare IVF Center (DHC)
Featured Commercial Partner
DHC is a dedicated fertility center in Bangkok’s Rama 9 area. It provides IVF, ICSI, embryo culture, PGT, egg freezing, embryo freezing, and embryo transfer services. DHC holds JCI, ISO 9001, RTAC, CAP, and UK NEQAS certifications. The center reports a 78% average embryo-transfer success rate for 2025 (approximately 80%), though this is not an individual prediction or guarantee. DHC uses advanced technologies including Embryoscope+, Geri incubators, IVF Witness, IMSI, and MACS. The June 2026 reference price for a basic single-cycle medical package is THB 490,000; final costs vary. Learn more about our partnership.
2. Bumrungrad International Hospital
Bumrungrad is a large multidisciplinary hospital in central Bangkok offering IVF, ICSI, and reproductive medicine services. The fertility team includes Dr. Phattaraphum Phophong, who has training in reproductive medicine and prenatal genetics. Its integrated setting may benefit patients needing access to other medical specialties. Current fertility team, laboratory, PGT, and price details should be confirmed directly.
3. Gift Fertility Clinic
Gift Fertility Clinic is a specialist fertility provider in Bangkok offering personalized IVF-related care. The clinic is led by Dr. Waranya Sirithanasarn, who has 13 years of experience and has treated over 1,100 infertility cases. Patients should confirm the treating doctor, laboratory, genetic-testing pathway, and all quotation inclusions directly.
4. Intrarat Hospital
Intrarat Hospital is a multidisciplinary hospital in Bangkok. Its marketplace profile primarily describes obstetrics and maternity services rather than a complete IVF laboratory profile. The listing names Dr. Orasa Teerakul (31 years of experience) and mentions ISO 9001:2015 certification. IVF, ICSI, embryo culture, PGT, and international-patient availability require direct written confirmation before including this hospital in a fertility shortlist.
5. PMG Hospital
PMG Hospital is a general hospital in Bangkok. Its marketplace profile describes prenatal care, obstetrics, and 24-hour nursing rather than a complete IVF laboratory profile. The listing names Dr. Ronnapop Kongpia as a full-time obstetrics and gynecology specialist with seven years of experience. IVF, ICSI, embryo culture, PGT, and international-patient availability require direct written confirmation.
6. Prime Fertility Clinic
Prime Fertility Clinic is located at Pearl Bangkok and offers IVF, ICSI, embryo freezing, assisted hatching, and international-patient care. The clinic is led by Dr. Poonkiat Punyamitr, who has 19 years of experience and has performed over 900 fertility procedures. The clinic holds JCI Ambulatory Care accreditation. Current services, inclusions, and pricing should be confirmed in a written quotation.
Key Questions to Ask Each Clinic
When evaluating clinics for IVF with PGT, consider asking:
- What is your live birth rate per embryo transfer for my age group?
- How many PGT cycles do you perform annually?
- What is your embryo biopsy technique and lab accreditation?
- Do you offer genetic counseling?
- What is the cost of a single cycle including PGT?
- What is your policy on multiple cycles or refund programs?
Factors That Influence Success Beyond Age
Success rates are not solely determined by age. Other factors include:
- Ovarian reserve (AMH, FSH, antral follicle count)
- Sperm quality and DNA fragmentation
- Uterine health (fibroids, polyps, endometriosis)
- Lifestyle factors (BMI, smoking, stress)
- Clinic laboratory standards and embryologist expertise
PGT can help select the best embryo, but it cannot compensate for poor egg or sperm quality. A thorough evaluation by a fertility specialist is essential.
Conclusion
IVF success rates decline with age, but PGT can improve per-transfer outcomes by selecting chromosomally normal embryos. When choosing a clinic in Thailand, verify current success data, lab standards, and costs directly. Use this comparison as a starting point for your research.

Frequently asked questions
What is the average IVF success rate for women under 35 using PGT?
For women under 35, IVF with PGT typically results in a live birth rate of 40–50% per embryo transfer. PGT can increase the per-transfer rate by selecting euploid embryos, but the overall success depends on the number of healthy embryos available.
Does PGT improve success rates for women over 40?
PGT can improve the per-transfer success rate for women over 40 by reducing the chance of transferring an abnormal embryo. However, the cumulative success per cycle is lower because fewer embryos are likely to be euploid. Multiple cycles may be needed.
How do Thailand IVF success rates compare to other countries?
Thailand IVF success rates are generally comparable to international standards, but clinic-specific data should be verified directly. Factors like lab standards, patient selection, and reporting methods can affect comparisons.
What is the cost of IVF with PGT in Thailand?
Costs vary widely by clinic and treatment plan. For example, Deep & Harmonicare IVF Center (DHC) offers a basic single-cycle medical package at THB 490,000 (June 2026 reference price), but final costs depend on medications, testing, storage, and additional procedures. Always request a detailed written quotation.
