It is possible to transfer embryos left over from two IVF arrests to three-generation IVF.
Three-generation IVF, also known as pre-implantation diagnosis or screening, in which embryos are genetically tested for genetic material before implantation in the uterine cavity, can screen healthy embryos for implantation and avoid the occurrence of genetic diseases. It is indicated for recurrent miscarriages due to chromosomal abnormalities.
The causes of two IVF fetal arrests are complex. Chromosomal abnormality is one of the causes of fetal arrest, therefore, if there are two consecutive fetal arrests, the pregnancy should be sent to pathological examination to determine whether it is related to chromosomal abnormality.
In addition to chromosomal abnormality, there may be other reasons such as poor endometrial tolerance, gynecological inflammation, luteal insufficiency, and immune factors, etc., which should be examined one by one.
If the cause of the two IVF abortions is diagnosed as chromosomal abnormality after relevant examinations, the remaining embryos can be transferred to third-generation IVF. Only the cost of third generation IVF is relatively high.
