There are women who do not achieve a full-term pregnancy because, at a certain point in their pregnancy, they suffer abortions that prevent the final birth of the baby. These women consider surrogacy a way of being able to be mothers, since they themselves cannot carry their baby to term during the 9 months of pregnancy.
It is considered a recurrent abortion when 2 or 3 abortions occur continuously. The causes of recurrent abortions can be genetic abnormalities in the gametes (eggs and sperm), immunological abnormalities, alterations in the uterine cavity or even problems in coagulation.
