reasons for cancelling embryo transfers

There are several reasons why the embryo transfer can be cancelled, either because no embryos have developed or because the endometrium is not receptive.

Embryo arrest may be caused by some genetic abnormality in the embryo that has been transferred. Therefore, when long culture is performed up to the blastocyst stage, it is possible that numerous embryos will stop and not continue their development. In addition, it may also happen that it does not produce the fertilization of the egg and sperm, so there would not be any embryos either.

If the endometrium does not have a trilateral aspect and a thickness of 7-9 mm, it is not recommended to perform the embryo transfer. These are the ideal characteristics for the endometrium to be receptive and favor the implantation of the embryo to give rise to a pregnancy.
