We understand that many couples can become frustrated when they do not achieve a pregnancy after undergoing one or more fertility treatments and this leads them to discard the option of trying again. Therefore, we would like to share with you some answers to the question: why, if I have good quality embryos, does IVF fail?
This situation is called repeated implantation failure, defined as the failure to obtain a pregnancy after undergoing at least two IVF treatments. We specialists must always ensure that the embryo has the necessary qualities to implant and if this does not happen after several good quality embryos have been transferred, we have to identify why they do not implant.
To identify this, there are 3 main activities:
To detect the causes of implantation failure, we have to:
In addition to chromosomal and genetic factors, implantation can also be affected by quality of life. Various studies have shown that living a healthy life and being physically active, as well as not smoking or drinking, have a positive impact on the quality of the embryos and their implantation.
For example, using tobacco significantly reduces the number of follicles, diminishing the ovarian reserve of the woman. Overweight, on the other hand, favors the appearance of genetic mutations and miscarriages.
The psychological aspect also plays an important role in In Vitro fertilization. When you undergo assisted reproduction treatment, there may be psychological pressure that is difficult to bear. Although it does not cause the treatment to fail, it is good to have emotional support during the process.
As we mentioned, the first step is to ensure that the embryos are of good quality. In the clinic, in 80% of the cases we allow the embryos to reach the third or fifth day of development to choose the best ones.
Secondly, we make sure that the embryo has the ideal conditions for implantation. We can do a preimplantation genetic diagnosis to detect if there is any underlying genetic condition.
Finally, we improve the receptivity of the endometrium with non-invasive treatments, which improve the conditions of the endometrium to receive the embryo and increase the possibilities of pregnancy.
