The Feasibility of Surrogacy contract Termination by each of parties

Surrogacy as a new way for fertility, in most cases is accompanied by contracting between infertile couples, surrogate mother, and the institution. Since having children is optional and the infertile couple can’t have children without assistive reproductive techniques aid including surrogacy, this question will arise as to whether each of parties can change his decision and avoid child birth or embryo creation during the embryo establishment till his birthday as they offer the zygote to the institute. The study of terminating this contract in rescission or termination format shows that rescission or termination by each of parties after 16th week that the embryo acquires spirit is not permitted at all. Also, terminating the contract between the first and 16th week is permissible only when in this time period we do not know the embryo as a human person.
