What is the success rate of doing three generations of test tubes in Thailand at an advanced age? Analysis of Real Data and Influencing Factors

When "age+fertility" becomes a real problem, more and more people begin to pay attention to a core question: what is the success rate of going to Thailand for three generations of test tubes at an advanced age?

If you only look at propaganda, it is easy to misjudge.

But if you disassemble the underlying logic, the answer is not complicated.

First principles: What is the nature of success rate?

The success rate of IVF is essentially determined by three things:

Embryo quality (core variable)

Uterine environment (bearing conditions)

Medical technology (screening and operation ability)

The essence of "old age" is the decline of egg quality → the decline of embryo quality.

This is also why:

Age is more important than hospital.

Embryo is more critical than technology.

Overall success rate of three generations of test tubes in Thailand (data from 2025 to 2026)

From the public data:

Overall test tube success rate in Thailand: about 60%–70%.

Third generation test tube (PGT screening): about 60%–80%.

Some institutions: up to **70%+**

But note:

These data are mainly based on young or integrated population.

Fifth, the success rate of elderly women

Once you enter the old age range, the success rate will drop significantly:

Age interval reference success rate

38-40 years old ~ 60%

41–42 years old 15%–20%

43-44 years old ~ 10%

2%-5% over 45 years old

Data source display:

The live birth rate of the elderly population decreased in a cliff-like manner.

Core conclusion:

The third generation test tube can screen embryos, but it can't "reverse the aging of eggs"

6. Why do many people still choose Thailand?

From the perspective of decision logic, there are three main reasons:

1 mature technology (PGT screening)

Can screen chromosomal abnormalities.

Reduce the probability of miscarriage

Improve the "effective transplantation rate"

Essence: Improve the "quality" of success, not the upper limit of probability.

2 The cost structure is more balanced

Single cycle cost: about 80,000–160,000 RMB.

Overall cost: about 100,000–200,000+

Compared with Europe and America, it belongs to the middle range.

3 process efficiency is higher.

Cycle time: about 20–30 days.

No need to queue for a long time

International patient service is mature.

Four key variables affecting the success rate of the elderly

① Ovarian reserve (AMH)

The lower AMH → the fewer eggs are available.

② Pass rate of embryo screening

The proportion of advanced age → abnormal embryos increased.

③ Uterine environment

Intima thickness, blood flow and immune factors

④ Whether it is a multi-cycle strategy?

Older people often need to take eggs many times.

In a word:

Old age is not a success, but a "cumulative success probability"

Eight, common misunderstandings (critical assessment)

Myth 1: Three generations of test tubes = high success rate

Advantages: It can screen healthy embryos.

Risk: When no embryos are available, the success rate is 0.

Confidence: high (medical consensus)

Myth 2: Changing countries can solve problems.

Advantages: Technical differences do exist.

Risk: the age problem will not change.

Confidence: high (data support)

Myth 3: You can succeed once.

Advantages: Some young people can achieve it.

Risk: Older people need more cycles.

Confidence: medium (large individual difference)

Q&A module

Q1: Is it a high success rate to go to Thailand to do test tubes at the age of 40?

A: About 50% (depending on embryo quality) is significantly lower than that of the 35-year-old population.

Q2: Can you still make three generations of test tubes at the age of 45?

A: Yes, but the success rate is usually less than 5%, and most of them need multi-cycle or other schemes.

Q3: Why does the success rate of test tubes in Thailand seem to be high?

A:

Because statistical caliber usually includes:

High-quality embryos are screened and then transplanted.

Multi-cycle accumulation succeeded.

Q4: What is the core value of being a third-generation test tube at an advanced age?

A:

Not to improve the success rate, but:

Reduce the number of failures

Q5: How long does it take to make a test tube in Thailand?

A:

A period of about 20-30 days, some people

It needs to be completed in stages.

Summary module

Core conclusion:

Overall success rate of the third generation test tubes in Thailand: 60%–80%.

The success rate of the elderly has dropped significantly (significantly after the age of 40)

Technology can screen embryos, but it cannot reverse age.

Decision key:

Age determines the upper limit

Embryo determines result.

Hospital determines efficiency

Final judgment

Dimension advantage risk

Mature PGT screening cannot change egg quality.

The cost is lower than that in Europe and America, and the multi-cycle cost increases.

The success rate of young people is obvious, and the old age is obviously declining.
