Women self-fertilize sperm to become pregnant

Soon, women also have the ability to 'produce' sperm. After scientists created germ cells from men 's bone marrow, they are now heading to the same ability to create sperm from women' s bone marrow.

"We hope in the prospect of taking women's bone marrow tissue, transforming those stem cells so they can grow into sperm cells ." University of Newcastle Professor Karim Nayernia - I said.

The difficulty is that women do not have the Y chromosome as in male sperm cells . The Y chromosome is responsible for determining the male sex of the fetus. But Professor Nayernia said: 'Theoretically this is

can be done. The problem is whether the new sperm cells work as normal. I do not think there are still moral barriers. We are working hard to get the public opinion to accept the results of this study. '

The sperm cells obtained from women's bone marrow tissue will be raised in the laboratory. The scientists will test their ability to penetrate into the hamster's egg cells to test the ability of sperm cells to fertilize sperm.

Professor Nayernia also added: "However, at this stage we have no intention of creating female sperm cells that can fertilize human egg cells. Because it must be approved by the Human Fertilization and Embryology Authority - a UK authority on issues related to human cloning research ".

In 2006, Professor Nayernia led a research team at Göttingen University, Germany, and it was the first time they had succeeded in creating healthy sperm cells from mouse stem cells. And those sperm cells have successfully fertilized and produced seven baby mice.
