Sperm Cells From Stem Cells

I don't usually blog about stuff like this here but I find it rather amazing. Scientists have figured out how to get sperm cells from stem cells! They were looking for proof that stem cells can generate any cell in the body and they got this during their experiments.

They can't be transplanted into the human body but their hoping it'll give them something to work with for male infertility. In fact, they're also trying to create sperm cells from the skin cells of infertile men.

Who would have thunk it? Not me.
