Repeated miscarriages can be treated with IVF, but IVF is not a solution to the problem of repeated miscarriages. If a woman who has had recurrent miscarriages is also suffering from tubal anomalies, i.e., at least one side of the fallopian tube is incompetent, and a further pregnancy is not possible in the natural way, IVF may be considered as an aid. There is also a category of repeated miscarriages that are found to be due to chromosomal reasons through etiological screening, such as chromosomal abnormalities in the fetus, or chromosomal abnormalities in the father or the mother, and IVF can be performed because multiple embryos can be obtained through IVF, and the third-generation IVF can perform genetic testing on these embryos. If it is clear that there is an abnormality of one type of chromosome or a certain genetic defect, the embryos carrying these defects can be removed through screening, and embryos with normal chromosomes can be selected for embryo transfer, thus reducing the number of miscarriages due to this cause.
