CLONING:
TEXT 1:
British scientists* have announced that it may soon be possible to clone human eggs and sperm from stem cells. Human life could be created in a science laboratory. This could provide more options for couples unable to have children of their own. It could also mean same sex couples could have children. The baby would share the genetic code of both partners. A further benefit would be to increase the supply of eggs and sperm for childless couples.
British Fertility Society secretary Dr. Allan Pacey described the research as an “exciting step forward”. He said the latest findings could greatly increase our understanding of how eggs and sperm are developed. He stressed that we are still in the early stages of fully understanding the biology of conception: “We still don’t really understand why some men and women can’t produce sperm and eggs of their own, and sadly for them that leads to infertility.”
