Did the Ends Justify the Means?

A new study in Human Reproduction makes a case for a simpler and more affordable alternative to in vitro fertilization—but its methods have raised ethical questions.  
The study’s aim was to help couples who carry genes for inherited diseases have healthy babies, which is currently done through selecting lab-tested IVF embryos.
Here, researchers paid women in Mexico to get artificially inseminated and have embryos “flushed out” from the womb. They found that these embryos were as healthy than those IVF embryos.

The journal's editor says the findings and the ethical debate are worth highlighting.
