Responsible Surrogacy

Information regarding the ethical aspects of the process

In many surrogacy processes, multiple embryos are transferred to the uterus of the surrogate. The scientific consensus is that as a greater number of embryos enhances the chance of a successful pregnancy, although there are differences of opinion on this matter. Either way, it is clear that the transfer of more than one embryo increases the chances of multifetal pregnancy, which majorly affects the course of pregnancy and entails greater risks for the surrogate (and the fetuses). At best, this will lead to the birth of twins (or more) – but instead, it might require selective fetal reduction due to medical risks. Therefore, we recommend discussing the number of embryos for transfer in advance and to determine in advance what to do in case of a multifetal pregnancy. In Israel, for example, the Ministry of Health recommended until recently the transfer of two embryos at the most (in all IVF processes including surrogacy), but today recommends transferring only a single embryo.
