Fertilization in vitro can increase the risk of twin birth even if only one embryo is placed in the uterus, say Japanese scientists.

At a conference on infertility treatment technologies, a group of scientists from Japan talked about a mechanism that helps to divide the embryo into two identical organisms, according to the Internet publication for girls and women aged 14-35 who are Pannochka. Net The modern direction in conducting artificial insemination is a reduction in the frequency of multiple pregnancies, as this increases the risk for both the mother and the children.

About 40% of all pregnancies that were conceived using artificial insemination technologies are twin. Often this happens because experts place more than one embryo in the womb to increase the chances of conception.

Earlier it was believed that a reduction in the number of embryos would help to solve this problem, but recent studies show that the very mechanism of artificial insemination still increases the risk of multiple pregnancies.

Another factor is that with a decrease in the number of embryos implanted in the uterus, the risk of a successful pregnancy is reduced, which can be solved with the help of new technologies that allow to extend the period of laboratory embryo cultivation.

However, a longer stay of the embryo in the cultural environment also increases its ability to divide into two organisms. According to many researchers, specialists who perform the embryo transfer to the uterus should carefully examine it to prevent future parents about the possibility of developing a multiple pregnancy.
