Miscarriages or spontaneous abortions that are repeated one after the other for no apparent reason and cause the loss of pregnancy, cause great distress in the woman who wishes to become a mother.
One of the latest research related to recurrent abortions, those that occur three or more times, points to an excess fertility of women. Notes that recurrent abortions could be caused by a failure in women to distinguish embryos of high and low quality.
Uterine conditions are so conducive in some women that it makes them too fertile to allow implantation of embryos, accepting embryos that other women would normally reject.
The study has not been massive, but it is enough to consider a new research path. Samples have been taken from the wombs of six women who had had normal pregnancies and another six who had suffered recurrent miscarriages.
Embryos of different quality were implanted in both groups and found that in women with normal fertility only high quality embryos grew, ignoring the rest, while in the other women both types of embryos grew, without discriminating their quality.
When a weak embryo is implanted, it can survive until the positive pregnancy test, but then it fails to prosper and a miscarriage occurs.
According to the author of the study, Professor Nick Macklon, "these women may be super-fertile and host embryos that would not normally survive until implanted."
The conclusion of this study is very interesting, mainly for women who have suffered a miscarriage. Disregarding the cause of what has happened causes feelings of guilt and anguish, and while not all spontaneous abortions are due to excessive receptivity, research such as this could be the key to finding a way to avoid them.
