Problem essence disassembly

Many people ask "choose PGT-A or PGT-M", which is a misunderstanding in essence:

This is not a "choice", but a "different type of problem".

Technical solution to problems

Is the number of PGT-A chromosomes normal?

Does PGT-M carry specific genetic diseases?

Conclusion first:

Old age → PGT-A is preferred.

There is a definite genetic disease → PGT-M is necessary.

Both can be done at the same time (in some cases)

Analysis of core mechanism

1 PGT-A: Solving the "Embryo Quality Problem"

Detection: whether the chromosomes are abnormal (such as one more or one less)

Applicable people:

≥35 years old

Repeated abortion

Multiple transplant failures

Data logic:

The proportion of chromosomal abnormalities in the embryos of older women increased significantly.

About 60% of repeated failures are related to chromosomal abnormalities.

Function:

Improve the success rate of single transplantation

Reduce abortion rate

Reduce trial and error

2 PGT-M: Solving "Genetic Risk Problem"

Detection: whether it carries pathogenic genes (such as thalassemia, SMA, etc.)

Applicable people:

Family history of hereditary diseases

Has been diagnosed with gene mutation

Medical essence:

Not to improve the success rate

But to avoid giving birth to sick children

Multi-perspective deduction

Reproductive medicine perspective

The core problem of old age: egg quality decline → abnormal chromosome increase.

So the priority is to solve: Is the embryo "available"?

Tendency: PGT-A

Genetic perspective

If you carry a disease-causing gene:

Even if the embryo is implanted normally, it may get sick.

Required: PGT-M

From the perspective of fertility strategy

Different goals:

Target technology

Improve the probability of pregnancy pgt-a

Avoiding genetic disease PGT-M

Advantages and risks

✅ PGT-A

Advantages:

Improve the efficiency of single transplantation

Reduce the risk of miscarriage

More suitable for the elderly.

Risk:

There are "false positives" → usable embryos may be eliminated.

Cost increase

Do not solve the problem of genetic diseases

✅ PGT-M

Advantages:

Clearly block the transmission of genetic diseases.

Has clear meaning for a specific group of people.

Risk:

Unable to screen for chromosomal abnormalities.

Still may fail or miscarry.

Gene loci need to be defined in advance.

Decision path

[Judgment process]

Is there a definite genetic disease?

↓

Yes → Select PGT-M.

↓

No → Is it ≥35 years old?

↓

Yes → Priority PGT-A

↓

No → According to the failure history.

Frequently asked questions Q&A

Q1: Do you have to be a PGT-A when you are old?

Not necessarily, but:

The risk of chromosome abnormality at ≥35 years old is significantly increased.

Doing PGT-A can reduce invalid transplantation.

Suggestion: Older people are preferred.

Q2: Is PGT-M more advanced?

No.

There is no hierarchical relationship between them, but their uses are different.

Q3: Do you have to succeed if you do PGT?

No.

Success depends on:

Uterine environment

internal secretion

Immune factors

PGT only solves the "embryo problem"

Q4: Can I do PGT-A and PGT-M at the same time?

Yes, it is common in:

Old age+carriers of genetic diseases

summary

In a word:

PGT-A: Improve the success rate (chromosome screening)

PGT-M: Avoiding Genetic Diseases (Screening Genes)

Core judgment:

Advanced age → Focus on solving "embryo quality"

Hereditary disease → "genetic risk" must be solved.

Strategy suggestion:

No hereditary diseases: PGT-A is preferred.

Hereditary disease: PGT-M is necessary.

Double risks: can be applied jointly.

conclusion

PGT-A and PGT-M are not substitutes, but complementary.

The essence of the problem of old age is "the probability of chromosome abnormality rising"

The essence of genetic problem is "gene defect transmission"

There is only one selection criterion: what kind of risk do you want to solve?
