This article aims to provide no more than a brief summary and overview of some of the principal legal questions which arise in connection with assisted human conception. There is no requirement of legal suitability for natural parenthood, though a child may be removed from parental care at birth if its welfare is considered to be at risk. Where medical or other assistance is required, however, the law and social judgements may impinge on the freedom of individuals to procreate. Commercial surrogacy has recently been criminalised, but private surrogacy arrangements without reward are not illegal-although any contract would probably be unenforceable through the courts.If medical intervention is required to achieve assisted conception, the availability of resources for NHS treatment, the physical and mental health of the prospective mother and father, and the welfare (or lack of it) of any prospective child, may be factors in deciding whether an infertility unit will offer treatment. Such pratices must not operate unfairly and must not discriminate on racial grounds. If treatment is provided, and a woman becomes pregnant, the ordinary abortion laws will apply and, it is thought, will extend to the selective reduction of a multiple pregnancy-there is no claim in English law for 'wrongful birth'. AID does not constitute adultery, and the law has recently been reformed to recognize children born following AID as legitimate to their social parents. A child may be regarded as the legitimate child of a surrogate mother's marriage, but where the baby is genetically distinct from the surrogate mother, the law, and is uncertain and as yet could be conflicting claims of parenthood without legislation. The storage and disposal of human gametes and embryos may raise problems of 'ownership'. © 1990 The British Council.
