If there is fluid inside the uterus (hydrometra), it would be best not to perform the embryo transfer, since the presence of this fluid can prevent embryo implantation. It would be best to freeze the embryos and transfer them in another cycle with a suitable endometrium. In any case, even if for some reason it is decided to perform the transfer, it is not advisable to introduce cannulas unnecessarily into the uterus, since this increases the possibility of injuring the endometrium.
The embryo transfer is critical for the success of the assisted reproduction treatment. If we have a good embryo and a receptive endometrium, but the transfer is not performed correctly, we can lose the possibility of achieving pregnancy. During the transfer, it is essential to avoid trauma to the uterus as much as possible. These would produce uterine contractions that would hinder embryo implantation.
