Sperm made from your own bone marrow

A research study by a team led by Karim Nayernia of the University of Newcastle upon Tyne in Britain has taken adult stem cells from bone marrow and developed immature sperm cells. Further research may result in fully mature and viable sperm.

While the research was aimed at helping men rendered infertile by cancer therapy, the startling implication is that no male is needed at all for reproduction. Two women could have their own biological daughter by fertlizing one woman's egg with sperm produced from the other woman's bone marrow stem cells.

The research results are published in the journal Reproduction: Gamete Biology.
