Understand the factors that influence IVF success for women over 40 in Thailand, including age, egg quality, donor eggs, and PGT-A testing. No specific success rates are provided, but key considerations are explained.
If you are a woman over 40 considering IVF in Thailand, you likely want to know your chances of success. While exact success rates vary widely by individual and clinic, the most important factors are your age, ovarian reserve, egg quality, and whether you use your own eggs or donor eggs. This article explains these factors and what questions to ask when consulting a clinic.
At a Glance: Key Factors for IVF Success After 40
- Age and egg quality: Natural decline in egg quantity and quality accelerates after 35 and more sharply after 40.
- Ovarian reserve: Measured by AMH and antral follicle count; lower reserve means fewer eggs retrieved.
- Donor eggs: Using eggs from a younger donor significantly increases success rates.
- PGT-A: Preimplantation genetic testing for aneuploidy can identify chromosomally normal embryos, which are more likely to implant.
- Clinic experience: Choose a clinic with expertise in treating women over 40.
How Age Affects IVF Success
Female age is the single most important factor in IVF success. As women age, the number and quality of eggs decline. By age 40, many eggs have chromosomal abnormalities, which reduce the chance of a healthy pregnancy. This is why success rates with a woman’s own eggs are lower for women over 40 compared to younger women. However, success rates can be much higher when using donor eggs from a younger woman.
Using Your Own Eggs vs. Donor Eggs
If you plan to use your own eggs, your doctor will assess your ovarian reserve through blood tests (AMH) and ultrasound (antral follicle count). A low reserve may mean fewer eggs retrieved, which can reduce the chance of having a chromosomally normal embryo. Many women over 40 consider using donor eggs, which bypasses the age-related egg quality issue. Donor egg IVF success rates are generally high regardless of the recipient’s age, as the eggs come from a young, healthy donor.
The Role of PGT-A (Genetic Testing of Embryos)
PGT-A is a test performed on embryos before transfer to check for chromosomal abnormalities. For women over 40, a higher percentage of embryos may be abnormal. PGT-A can help select embryos with the best chance of implanting and developing into a healthy baby. However, PGT-A does not guarantee pregnancy, and some women may have no normal embryos to transfer. Discuss with your clinic whether PGT-A is recommended for your situation.
Questions to Ask Your Clinic
When consulting a clinic in Thailand, consider asking:
- What is your experience treating women over 40?
- What tests will you do to assess my ovarian reserve?
- What are the options if my own eggs are not viable?
- Do you recommend PGT-A, and what is the process?
- What is the typical number of eggs retrieved for women my age?
- What support services are available (counseling, etc.)?
Next Steps
Start by researching clinics that specialize in IVF for women over 40. Schedule consultations to discuss your specific medical history and receive personalized advice. Remember that success rates are not the only measure; consider the clinic’s approach, transparency, and the comfort you feel with the medical team.

Frequently asked questions
Can I have a successful IVF after 40 with my own eggs?
It is possible, but success rates are lower due to age-related decline in egg quality. Your doctor can assess your ovarian reserve to give a more personalized estimate.
Is donor egg IVF more successful for women over 40?
Yes, donor egg IVF typically has higher success rates because the eggs come from a younger donor, bypassing age-related egg quality issues.
What is PGT-A and should I consider it?
PGT-A tests embryos for chromosomal abnormalities. For women over 40, it can help select embryos with the best chance of implantation, but it does not guarantee success and may result in no normal embryos.
How do I choose a clinic in Thailand for IVF after 40?
Look for clinics with experience treating older women, transparent communication about success rates, and services like donor eggs and PGT-A. Schedule consultations to ask specific questions.
