Intended parents attend the birth of their child by a gestational surrogate.<unk>  is an arrangement, often supported by a legal agreement, whereby a woman (the gestational carrier) agrees to bear a child for another person or people, who will become the child's parent(s) after birth. People may seek a<unk>  arrangement when pregnancy is medically impossible, when pregnancy risks are dangerous for the intended mother, or when a single man or a male couple wish to have a child.<unk>  is considered one of many assisted reproductive technologies. In<unk>  arrangements, monetary compensation may or may not be involved. Receiving money for the arrangement is known as commercial<unk> . The legality and cost of<unk>  varies widely between jurisdictions, sometimes resulting in problematic international or interstate<unk>  arrangements. Couples seeking a<unk>  arrangement in a country where it is banned sometimes travel to a jurisdiction that permits it. In some countries,<unk>  is legal only if money does not exchange hands. (See:<unk>  laws by country and fertility tourism.) Where commercial<unk>  is legal, couples may use the help of third-party agencies to assist in the process of<unk>  by finding a surrogate and arranging a<unk>  contract with her. These agencies often screen surrogates' psychological and other medical tests to ensure the best chance of healthy gestation and delivery. They also usually facilitate all legal matters concerning the intended parents and the surrogate.
