Surrogacy in which the woman who is the surrogate for the intended pregnancy provides the eggs (through her own ovulation); is impregnated by assisted insemination; carries (or 'gestates') the pregnancy; gives birth; and then gives up the baby to the person who commissioned the surrogacy arrangement. Also known as genetic-plus-gestational surrogacy. The surrogate is as much the biological mother of the child as if she had conceived in natural circumstances, except that the male by whom she has been impregnated has no prior social relationship with her. No countries other than the US, where commercial surrogacy can be legal, have encouraged the practice, whether for altruistic or commercial reasons.

Achieving pregnancy with the help of a third party to provide any of: the spermatozoa (see donor insemination); the oocytes (egg donation); or the uterus (surrogacy: see gestational surrogacy and traditional surrogacy). Current issues surround the question of whether or not to inform the child of his or her origins, whether the donor or surrogate should be anonymous or take some part in the child's upbringing, exploitation and autonomy, and (in the case of sperm donation) access to sperm banks by women not in a heterosexual relationship with a sterile man.
