Without Eggs or Sperm

World Economic Forum-linked researchers have announced a breakthrough in creating human embryos using stem cells, without the need for eggs or sperm, raising serious ethical and legal questions about the future of human reproduction.

The lab-grown human embryos were produced in a joint project between Cambridge University and the California Institute of Technology and replicate natural embryos in the earliest stages of human development.

Last week the World Economic Forum promised a future in which lab-grown humans will be controlled for compliant traits. That future appears to have arrived sooner than many people expected.
