Ethics of embryo selection: balancing CF risk, parental love, and eugenics concerns

The Ethicist argues that using IVF with preimplantation genetic testing to avoid CF‑risk embryos can be ethically permissible, since selecting embryos is about health states rather than devaluing existing people. While the term “eugenics” is loaded, the key is whether such selection expresses contempt for those with the condition. Personal motives (like wanting a daughter) should be weighed carefully, and the analysis acknowledges the limits of genetic testing and the importance of valuing the current child while considering future risks.
