By degrading women to purchasable “baby producers”, commercial surrogacy has been accused by feminists of commodifying women’s bodies in a manner akin to prostitution. Also creating a commercial market for human bodies is inherently exploitative. Some argue that commercial surrogacy strips birthmothers of their natural rights. Most countries consider the birthmother (not necessary the biological mother) to be the legal mother unless she freely chooses to put her child up for adoption (without coercion or payment).

Numerous ethical questions have been raised with regards to surrogacy. They generally stem from concerns relating to social justice, women’s rights, child welfare, bioethics and societal traditional values. In german media mostly the women’s rights concerns are mentioned. There seems to be no short answer to your question.
