Motherless babies possible as scientists create live offspring without need for female egg
This looks like a major challenge to conventional knowledge about how humans are made. Also possibly offering an option for gay men who want children.
Motherless babies could be on the horizon after scientists discovered a method of creating offspring without the need for a female egg.
The landmark experiment by the University of Bath rewrites 200 years of biology teaching and could pave the way for a baby to be born from the DNA of two men.
It was always thought that only a female egg could spark the changes in a sperm required to make a baby, because an egg forms from a special kind of cell division in which just half the number of chromosomes are carried over.
Sperm cells form in the same way, so that when a sperm and egg meet they form a full genetic quota, with half our DNA coming from our mother and half from our father.
But now scientists have shown embryos could be created from cells which carry all their chromosomes which means that, in theory, any cell in the human body could be fertilised by a sperm.
