It is absolutely possible to isolate human egg cells (it's done all the time for in vitro fertilization) and .... well, do in vitro fertilization. What's illegal in most countries is making directed genetic changes to them, aka what I've been doing to the mice.
In theory, it would work the same. Isolate egg cells, bring them together with sperm, wait, inject stuff, wait, transfer them to a woman's uterus. Wait 9 months, congratulations, you have a baby!
Now, I'm assuming you're female, or else the part about "the babies having genes from you and your girlfriend" wouldn't make much sense.
There actually has been a case where researchers created a mouse with two mothers (Read about it here) but so far, it has not been applied to humans. Might also not yet be possible with our technology, but could be possible in the future.
"What's illegal in most countries is making directed genetic changes…" That's what I thought.
This should be researched more, so that some day it would be legal. And I wouldn't mind that some day being soon, since like my mum happily likes to remind me on monthly basis, I have soon passed the suitable reproduction age, lol.
And yes, I am female just like my better half. Not too easy to get babies together even if there was genes only from one us. So maybe I'll just ditch the idea all in all...
