Social sex selection and the balance of the sexes: empirical evidence from Germany, the UK, and the US.

Preconception sex selection for nonmedical reasons is one of the most controversial issues in bioethics today. The most powerful objection to social sex selection is based on the assumption that it may severely distort the natural sex ratio and lead to a socially disruptive imbalance of the sexes. Based on representative social surveys conducted in Germany, the United Kingdom, and the United States, this paper argues that the fear of an impending sex ratio distortion is unfounded. Given the predominant preference for a "gender balanced family," a widely available service for social sex selection is highly unlikely to upset the balance of the sexes in Western societies.
