Researchers of the Northeast England Stem Cell Institute have created artificial human sperm cells using embryonic stem cells.
Scientists claims that within 10 years this technique could also be used to allow infertile couples to have their own children. It could even be possible to create sperm from female stem cells which would ultimately mean a woman having a baby without a man. It may also prove useful for young boys subjected to chemo treatment which left them infertile.
This is the first time human sperm has been created in a laboratory. The experiment has proved controversial and threatens to reignite the fierce debate of embryo research. Professor Nayernia, who heads the research, says "This is very amazing and very exciting. They have heads, they have tails and they move. The shape is not quite normal nor the movement, but they contain the proteins for egg activation." {He also claimed that his team has already used the technique on mice, which have produced offspring. The mice all died shortly after they were born.}
"Soon we will be able to isolate stem cells from the skin to generate sperm cells," he said. "This would enable us to look at individual stem cells from an infertile patient and find out what is the cause...We hope that eventually this could help create sperm for infertile men."
