According to experts, a large number of spontaneous abortions occur, the calculations consider that at least 50% of all conceptions end in an abortion. There are several causes that cause it, infections, abnormalities, etc., but there are still other reasons unknown to the experts, for this reason the study being carried out by experts from the medical school of the University of Granada is very important. In this study we will try to determine all those mechanisms that can cause a miscarriage.
According to García Olivares, nature is very wise and has a series of filters ready to eliminate the embryos conceived when something is not going well. Well, without wanting to contradict the expert we will also say that nature has changed and that sometimes this does not happen, the proof is the thousands of children who come to the world with various genetic problems. Natural selection works in animals, that is so, although it seems that in humans something changes. The researcher says that the high reproductive rate is associated with the large number of filters that will allow only the best prepared children to be born. Knowing the mechanism of these filters such as the acceptance or rejection of the embryo conceived by the future mother, determining what infections and how they cause the loss of the embryo, etc., is essential. For example, knowing the mechanisms, it is possible to know if the implantation of an embryo will be rejected and therefore, with pharmacological help it will be possible to make the pregnancy come to fruition.
The truth is that there are many mechanisms by which the future mother can reject the embryo or not, this is a task that has kept researchers busy for 15 years and the advances made allow for greater success in conceptions. There are many unknowns, one highlighted by researchers is the action of the so-called NK or Natural Killers, cells that attack the fetus inducing abortion. They are cells that are activated in case of abortion, but not all the causes of their activation are known.
In short, it is intended to demonstrate that there is an immune component that causes normal pregnancy or abortion, but as we have said, investigations are still in progress.
