....And he warned that manipulating stem cells to develop into mature sperm could cause permanent genetic changes in the sperm, making the cells unsafe to use in fertility treatments.

Just how redundant are men trying to make themselves?

At least I know there is no more omnipotent than God's natural sperm. Same thing with a natural egg.

Humans are always trying to match God's work. I wonder when they'll realize to stop.

I'm afraid to see medical books in the future saying that fertilization is a union of sperm and egg, or a modified stem cell and egg. lol

I think you are wrong Robutix, future medical books will define fertilization as a union of sperm and egg, whether natural ones or modified stem cells, one as sperm and the other one as an egg. And pregnancy will be defined as is the developing of one or more embryos or fetuses in artificial wombs. I don't konw if I should LOL or COL (cry out loud)
