Comartemis said: They could be test tube babies. I think I heard somewhere that we have the technology now to implant a woman's genetic data into a sperm cell and let one woman artificially inseminate another.
There's a proposal for a process like that, however it's still only a theory. There's no laboratory data to back it up. The guy who came up with it did patent the idea, but only 'just in case' it worked. If it ever did, no doubt it'd be ungodly expensive.
In cases like this I think it's best to just enjoy the image rather than think too deeply about how it came about ^^"
