Sperm grown from bone marrow13th April 2007
Researchers in Germany have succeeded in making sperm cells from human bone marrow.
Scientists at the Universities of Göttingen and Münster and the Medical School of Hannover announced they had made immature sperm cells, and that they hope to find ways to develop them into mature sperm over the next five years.
They used adult stem cells from bone marrow taken from male volunteers.
If mature sperm are grown as a next step, the development could have profound implications for fertility treatments.
