Do Sperm Multiply?

Question

Do sperm actually multiply? I thought they were end stage?

Answer

That's absolutely right. Sperm can't, but what they've been able to do is to make the cells that are the stem cells that make the sperm grow in the dish and then produce sperm in the dish, which is the thing that's eluded scientists for many, many years. That's why it's such big breakthrough.
