The Parents Who Want Daughters—and Daughters Only. Sex selection with IVF is banned in much of the world. Not in the U.S. by Emi Nietfeld
"Sex selection was once controversial in the U.S. and is banned in almost every other country. Many Americans unaware of the process still assume that it’s that way. In reality, it has now become a standard part of IVF here. For some, the option to sex select is a perk of an otherwise exacting process. For others, it’s the whole point of doing IVF in the first place.

"Still, “the very act of sex selection is sexist,” argues Arianne Shahvisi, a professor of philosophy at Brighton and Sussex Medical School in the U.K., where elective sex selection is illegal.

"It’s not just the U.K. Virtually all the industrialized world—including Canada, Australia, and every European country besides Cyprus—bans sex selection except in rare medical cases. Most nations prohibit the practice on the grounds that it promotes sexism and that the children born from it may be harmed by gendered expectations. Widespread preference for a certain sex can also skew the population—as in India and China, where abortion and infanticide of girls have resulted in tens of millions more men than women.

"In 1994 the American Society for Reproductive Medicine, the nonprofit that provides the industry’s professional guidelines, condemned sex selection for nonmedical reasons. Yet with no enforcement power, the guidelines remained just that. Unlike in most peer nations, IVF in America is mostly privately paid and weakly regulated. Instead, market forces dominate. By 2018, despite the ASRM’s recommendation that they not offer sex selection, 75 percent of clinics continued to provide the service. Since then, the ASRM’s ethics committee has updated its position to a neutral stance."
