ZusammenfassungVersuche zur Geschlechtswahl bei der Befruchtung führten in jüngerer Zeit zu anwendbaren, wenngleich noch eingeschränkt erfolgssicheren Techniken. Deren ethische und rechtliche Bewertungen stehen im Mittelpunkt dieser Abhandlung. In Gesellschaften und Kulturen mit traditioneller Bevorzugung männlicher Nachkommenschaft gibt es einerseits ein starkes Interesse für die Geschlechtswahl, andererseits wird in einigen westlichen Ländern der vorgeburtlichen Geschlechtswahl sehr geringe praktische Bedeutung beigemessen. Dabei unterscheidet sich die Verfügbarkeit der entsprechenden reproduktionsmedizinischen Verfahren von freier Zugänglichkeit zu allen Methoden (Präimplantationsdiagnostik, Spermatozoentrennung usw.) des Fortpflanzungsmedizinmarkts (USA) bis (...) hin zu strenger Reglementierung (Deutschland). Es wird anhand der wissenschaftlichen Literatur der Frage nachgegangen, welche für die Begründung rechtlicher Regelung beachtlichen sozialen oder gesundheitlichen Gefährdungen durch präkonzeptionelle Geschlechtswahl verursacht werden könnten, und welche Gründe es andererseits für die Zulässigkeit sozial motivierter präkonzeptioneller Geschlechtswahl gibt.

Policy-makers have attempted to frame the ethical requirements that are relevant to the creation of human beings via reproductive technologies. Various reports and laws enacted in New Zealand, Canada, Australia, and Britain have introduced tests for how we should weigh child welfare when using these technologies. A number of bioethicists have argued that child welfare should be interpreted as a “best interests” test. Others have argued that there are ethical reasons why we should abandon this kind of test. I will (...) argue that at least some of the relevant policy can be interpreted as requiring those wishing to exercise their procreative liberty to have a reasonable plan to care and nurture any resulting child, thereby respecting the internal preconditions of that liberty. This interpretation of child welfare requirements answers some of the ethical worries about a child welfare test. (shrink)

The non-identity problem arises when an intervention or behavior changes the identity of those affected. Delaying pregnancy is an example of such a behavior. The problem is whether and in what ways such changes in identity affect moral considerations. While a great deal has been written about the non-identity problem, relatively little has been written about the implications for physicians and how they should understand their duties. We argue that the non-identity problem can make a crucial moral difference in some (...) circumstances, and that it has some interesting implications for when it is or is not right for a physician to refuse to accede to a patient's request. If a physician is asked to provide an intervention (identity preserving) that makes a person worse off, then such harm provides a good reason for the physician to refuse to provide the intervention. However, in cases where different (identity-altering) interventions result in different people having a better or worse life, physicians should normally respect patient choice. (shrink)

BACKGROUND: -/- Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concern is based on the assumption that a freely available service for sex selection will distort the natural sex ratio and lead to a severe gender imbalance. However, for a severe gender imbalance to happen, at least two conditions have to be met. First, there must be a significant preference for children of a particular sex, and second, there must be a considerable demand (...) for preconception sex selection. To ascertain whether or not these two conditions are met, we have conducted a survey in Germany. METHODS: -/- As a representative sample of the German population, 1094 men and women aged 18-45 years were asked about their gender preferences and whether or not they could imagine selecting the sex of their children through flow cytometric separation of X- and Y-bearing sperm followed by intrauterine insemination. RESULTS: -/- 58% of respondents stated that they do not care about the sex of their offspring. 30% wish to have a family with an equal number of boys and girls. 4% would like to have more boys than girls, 3% more girls than boys, 1% only boys and 1% only girls. For first-borns, however, there is still a preference for boys over girls. While 75.6% claimed to have no gender preference, 14.2% would like their first child to be a boy and 10.1% would like their first child to be a girl. Whereas 6% could imagine taking advantage of preconception sex selection, 92% found this to be out of the question. Even in the hypothetical case that a medication for sex selection were ever to become available, 90% stated that they would not want to use it. CONCLUSION: -/- Given that a majority does not seem to care about the sex of their offspring and only a minority seem to be willing to select the sex of their children, a freely available service for preconception sex selection for non-medical reasons is rather unlikely to cause a severe gender imbalance in Germany.

This brief paper summarizes a series of postal investigations on the acceptance of selection for X or Y spermatozoa. These were conducted mainly in Germany but also in the UK, the Netherlands and the US. Selected families were approached with a series of questions about their wish to use sperm selection, and their choice of boys or girls. In general, large majorities opposed this approach for family balancing or sex selection on the basis of cost and inconvenience of the treatment. (...) The view was expressed that its use in medicine was more acceptable. Care was taken to compose a series of open questions to particular sections of the population, e.g.men versus women, differing ages, and families with imbalanced sex ratios. More favourable responses arose, for example in pregnant women. Overall, all four nations had large majorities against the use of sex selection. (shrink)

After its review of the Human Fertilization and Embryology Act of 1990, the Department of Health concluded that the British Parliament ought to outlaw sex selection for any but the most serious of medical reasons. This paper reviews the most frequently expressed objections to social sex selection and concludes that there is simply no moral justification for prohibiting parents from using sex selection technology to balance their families.
