s prior to implantation. When used to screen for a specific genetic condition, the method also makes it possible to select embryos with intersex conditions for termination.

and others. Surgical interventions on children with intersex conditions are contentious and may lead to selection for other traits like same sex attraction. Robert Sparrow states that intersex conditions are comparable to sexual orientation in that harms may be associated with a "hostile social environment". He concluded that the acceptability of elimination of intersex conditions has "uncomfortable" implications for "other nonpathological human variations" that do not affect physical health.

In response to Sparrow, Georgiann Davis argues that such discrimination fails to recognize that many people with intersex traits led full and happy lives, and that the "intersex community is only "invisible" to those who choose to ignore it", while "the medical profession, not the intersex trait itself, is a major source of the social and psychological harm that perpetuates intersex stigmatization and the "hostile social environment" that individuals with intersex traits encounter". Jeff Nisker links the elimination of intersex conditions to their pathologization, describing how " ce a difference becomes a medical disorder to which the medical profession is dedicating time and resources to prevent, procedures to this end become endowed with appropriateness".

in 2010 constructs "low interest in babies and men – and even interest in what they consider to be men's occupations and games – as "abnormal", and potentially preventable with prenatal dexamethasone". The authors state that "weak and unsupported conclusions" of investigations into the attempted "prevention of benign behavioral sex variations" indicates gaps in the ethical management of clinical research. In 2012, Hirvikoski and others described a lack of long-term follow-up studies of individuals exposed to prenatal treatment, and the results of a 10-year Swedish study of 43 mothers and children. The authors found evidence of unacceptable side-effects in their study, including neurological consequences. Treatment with dexamethasone was discontinued in Sweden.
