Ethics and Society: Filiation in assisted reproduction: potential conflicts and legal implications

Filiation, or a person's parentage, is one of the major componentsof someone's identity, often with important implications forthat person's welfare in social and personal terms. Fertilityspecialists are enjoined to consider the welfare of the child,and this is a legal requirement in assisted reproduction techniquesin the UK. This paper is in three parts, discussing some ofthe potential problems regarding filiation of the prospectivechild born of assisted reproduction techniques, in relationto the use of gametes and embryos. The first two parts concentrateon the status of children born as a result of treatment givenposthumously, and on filiation problems associated with donationof gametes or embryos, and surrogacy. The third part comparesBritish and French legislation with special regard to the welfareof the child, as well as underlining the common trends and principlesenunciated in both legislations. This is particularly appropriateat a time when the European Society for Human Reproduction andEmbryology is about to issue ethical guidelines in assistedreproduction, and when both the Council of Europe and the EuropeanCommission have commissioned studies on the implications ofthe assisted techniques, including those concerning status ofthe potential children.
