(Nature) – The amendment is intended to regulate assisted reproduction, including the payment of surrogate mothers, donations to egg and sperm banks and the fertilization of more than three eggs at a time.

Such restrictions are intended to address Mexico’s thriving reproductive tourism industry, which has few protections for surrogate mothers. But the proposed amendment would have prohibited a scientific world first that took place in Mexico: the conception of a baby with DNA from three people.
