Raunigk did not have a partner, and she had just entered menopause, so she needed donor eggs and donor sperm to be able to have children. But it is illegal in Germany to undergo artificial insemination with both a donor egg and sperm. So Raunigk had to travel to another country to seek help. She eventually ended up at the Ukraine to find a doctor that would help her through the procedure.
Because the eggs and sperm are donors, Raunigk will not know who the biological parents of her children are. There are ways to find out, but Raunigk seemingly does not mind not knowing. She knows that she will treat them like her own children and she is confident that they will also see her as their true mother.
