"He says he created these children and he has a responsibility to them"

Mr Johnson began donating sperm after arriving in New Zealand in May to work on Christchurch earthquake recovery. He created an online persona “chchbill” on unofficial websites for those seeking sperm donors…

He said he turned to sperm donations because Mrs Johnson had a hysterectomy two years before they married.

Mr Johnson, who could not be contacted, said at the time the desire to father a child was “a need that I have”. “Reproduction and having children is as basic a human need as eating,” he said in December.
