The MIT Technology Review site reports that despite the recent controversy With China genetically engineering disease-resistant babies, Harvard University is planning on editing sperm cells in order to improve tomorrow's children.
To be clear, there are no embryos involved—no attempt to make a baby. Not yet. Instead, the researchers are practicing how to change the DNA in sperm collected from Boston IVF, a large national fertility-clinic network. This is still very basic, and unpublished, research.
Yet in its purpose the project is similar to the work undertaken in China and raises the same fundamental question: does society want children with genes tailored to prevent disease?
