The Third Generation IVF Technique (PGD), as a preconception diagnosis, offers another option for couples at high risk of having a genetic disorder. Is it mainly people suitable for doing three generations of IVF? Let's look down with the Belai test tube!
Pre-implant embryo genetic diagnosis or screening techniques, abbreviated as PGD or PGS, are commonly known as third-generation IVF techniques.
The "third generation of IVF technology" mainly solves the problems caused by genetic factors, avoids the occurrence of related genetic diseases in the next generation, repeated miscarriages caused by chromosomal abnormalities, and achieves the purpose of eugenics.
Who are suitable for PGT III IVF?
1. Chromosomal abnormalities: including mutual translocation, Roche translocation, inversion, complex translocation, pathogenic micro-deletion or micro-repetition, etc.;
2. Single-gene diseases: such as thalassemia, hemophilia, polycystic kidneys, hereditary deafness, phenylketonuria, etc.;
3. PGT-A: there are the following factors: advanced age, 38 years old and above; Repeated spontaneous abortion of unknown cause; Repeated implantation failures for unknown reasons, etc., can be transferred without chromosomal abnormalities to improve clinical pregnancy rates, reduce miscarriage rates and birth defects.
In one of the following cases, it is not suitable for three-generation test tubes
1. Genetic diseases that are currently genetically diagnosed or genetically located.
2. The choice of non-disease traits, such as gender, appearance, height, skin color, etc.
3. In other cases where it is not appropriate to implement PGT, PGT technology will not be implemented.
Finally, I want to tell everyone that IVF is not a panacea, we must improve our lifestyle and face it with peace of mind. Nurturing life is also "fast but not fast"
