Gender eugenics? The ethics of PGD for intersex conditions
1a Monash University.
Insights
Preimplantation genetic diagnosis (PGD) may be ethically used to prevent births of children with intersex conditions/disorders of sex development (DSDs) that pose serious medical risks. Ethical considerations for cosmetic variations and broader diversity attitudes are also discussed.
Area of Science:
- Bioethics
- Reproductive Genetics
- Medical Ethics
Background:
- Pediatric surgeries for ambiguous genitalia are ethically controversial.
- The ethics of using preimplantation genetic diagnosis (PGD) to prevent intersex conditions/disorders of sex development (DSDs) remains underexplored.
- Conditions like congenital adrenal hyperplasia (CAH) and androgen insensitivity syndrome (AIS) are examples of DSDs.
Purpose of the Study:
- To discuss the ethical implications of employing PGD for preventing DSDs.
- To evaluate the moral permissibility of PGD for medically risky DSDs versus cosmetic variations.
- To explore the broader societal impact of PGD use on attitudes toward diversity.
Main Methods:
- Ethical analysis and philosophical argumentation.
- Review of existing bioethical debates on DSD interventions.
- Conceptual exploration of PGD's role in reproductive decision-making.
Main Results:
- PGD is suggested as morally permissible for DSDs associated with significant medical risks.
- PGD for non-medically indicated, 'cosmetic' variations in sexual anatomy is argued to be more defensible than initially presumed.
- The ethical arguments for PGD in cosmetic variations have profound implications for diversity acceptance.
Conclusions:
- PGD presents a complex ethical landscape regarding DSDs and sexual anatomy variations.
- The potential benefits for serious medical conditions must be weighed against broader societal values.
- Further ethical deliberation is required concerning PGD's impact on diversity and acceptance of human variation.
Abstract:
This article discusses the ethics of the use of preimplantation genetic diagnosis (PGD) to prevent the birth of children with intersex conditions/disorders of sex development (DSDs), such as congenital adrenal hyperplasia (CAH) and androgen insensitivity syndrome (AIS). While pediatric surgeries performed on children with ambiguous genitalia have been the topic of intense bioethical controversy, there has been almost no discussion to date of the ethics of the use of PGD to reduce the prevalence of these conditions. I suggest that PGD for those conditions that involve serious medical risks for those born with them is morally permissible and that PGD for other "cosmetic" variations in sexual anatomy is more defensible than might first appear. However, importantly, the arguments that establish the latter claim have radical and disturbing implications for our attitude toward diversity more generally.
