Scientists have found that freezing embryos for in vitro fertilization is only beneficial for them.
Analysis of the results of 11 studies with the participation of 37,000 women who became pregnant through extracorporeal fertilization shows that freezing embryos produces an amazing effect.
Until now, physicians have used the method of fertilization of an ovum outside the mother's body and, convinced of the viability of the embryo, made its implantation into the woman's womb. The remaining embryos are usually frozen in case the woman decides to apply to this procedure again if the first attempt fails or to give birth to yet another child.
In the first procedure of in vitro fertilization, priority was always given to "fresh" embryos that were not subjected to the freezing procedure. Physicians considered them the most suitable for fertilization.
However, a group of scientists from the University of Aberdeen, based on an analysis of the findings, claims that the process of gestation and course of pregnancy is much better if the mother was implanted with an embryo that was subjected to freezing and then thawed.
According to the data received, when the patients were "frozen" embryos, the threat of bleeding throughout the pregnancy period decreased by 30%, the risk of premature births and the risk of a child's death after birth was reduced by 20%. In addition, the likelihood of the birth of a baby with underweight also decreased by 30-40%.
With regard to congenital malformations, the specialists did not find an increase in the number of such children compared with the "fresh" embryos born from fertilization.
It is noteworthy that in the intensive care unit most often turned out to be children whose mother was "planted" a "fresh" embryo.
Scientists call the results of research very encouraging. If the success of women's fertilization with embryos that have been frozen is confirmed, then this procedure can be considered absolutely safe for both the child and the mother.
