I pitched this exact idea to my fiancé a few days ago (and have no clue why it came up). she didn't think it was a good idea, but now I can tell her that it was good enough to patent.
She and I don't want to make kids, so it isn't immediately applicable anyway. That being said, I am an experimental nuclear and particle physics PhD student, so I am at least 85% sure that I could convince my boss that we need a medium size centrifuge in the lab and make some... adjustments... upon completion.
We (maybe) want kids, she just doesn't want to ever be pregnant, so adoption is our route if anything.
This would be the worst of both worlds: A pregnancy that we don't even get one of the little shits from! She'll have to deal though, science demands that we try it at least once.
