It is argued that in commercial surrogacy, the rights of the child are often neglected as the baby becomes a mere commodity within an economic transaction of a good and a service. Such opponents of surrogacy argue that transferring the duties of parenthood from the birthing mother to a contracting couple denies the child any claim to its “gestational carrier” and to its biological parents if the egg and/or sperm is/are not that of the contracting parents. In addition, they claim that the child has no right to information about any siblings he or she may have in the latter instance. The relevance of disclosing the use of surrogacy as an assisted reproductive technique to the child has also been argued to be important for both health risks and the right's of the child.
