1) Two eggs are fertilised with sperm, creating an embryo from the intended parents and another from

the donors 2) The pronuclei, which contain genetic information, are removed from both embryos but

only the parents’ are kept 3) A healthy embryo is created by adding the parents’ pronuclei to the donor

embryo, which is finally implanted into the womb. Hetianga mi pathum chi atanga nausen siam hi kum
