As I said I think artifical wombs for ZEF's under 12 weeks gestation are NOT going to occur because they will be unable to keep a ZEF that is under 12 weeks gestation alive long enough for a transfer to an artificial womb.
The only way I could ever envision an artifical womb bringing a ZEF under 12 weeks gestion to term would be if the woman's egg was fertizled inside the artifical womb.
Trying to transfer any ZEF under 12 weeks gestion will most certaily kill it.
We've seen some amazing technological advancements in our day.
At this point, I would neither speculate about the degree of resiliance of a ZEF or second guess science's ability to create the most incredible breakthroughs.
We all know we're moving in the direction of more and more incredible breakthroughs.
Who really knows what's next and when.
The only reason I went along with your sceanio was to make to it clear that most women who did not want an unwanted pregnancy only wanted not to be pregnant.
I think most woman who seek an abortion would be Ok with letting the ZEF live and grow into a baby as long she did not have to be one to carry it to full term using her body, possibly ruining her health ,and/or making her responisible for raising the baby.
Most women who choose abortion just want the ZEF out of their body.
Though it's pretty clear that women who choose abortion want the ZEF out of their body, the actual underlying reasons would determine whether they were okay with the ZEF being brought safely to term by other means.
For those women whose health is at risk, they may indeed want the ZEF to be brought to term by other means if the conception/pregnancy wasn't undesired, with an eye to keeping the infant for themselves as opposed to giving the infant up for adoption.
But if the conception/pregnancy is undesired, then it would depend on the woman.
How many women would want the Z or E to continue by submitting to a more rigorous surgical process? If they didn't realize a Z/E was a living human organism, they might be more inclined to just abort chemically or through surgery comparatively less risky than a transfer. It's all about information and values. The pro-choice camp is obviously, as evidenced by PP and NARAL and the majority of pro-choice posters here, loathe to even
acknowledge the living human organism nature of the Z or E, let alone mention it. So many women are sadly never accurately informed before making a decision. Especially with regard to Zs and Es, it's greatly about the information the woman possesses in combination with her values.
How many women would want to help others have a child if it meant having to endure a likely more risky transfer surgery. Again, that depends on the awareness of the woman and her vaules.
Then there are those who want to avoid complications of the recipient woman changing her mind later, closer to birth, choosing to give the birthed infant up for adoption against the previous agreement with the biological mother .. and then there are woman who don't want to have a teenager seeking them out 19 years later asking them all kinds of questions.
Those women who presently use chemical/surgical abortion as a method of (albeit mostly secondary) birth control would likely just choose the more simple less-hassle procedure that is abortion without giving it a second thought. For many of these women, a Z or an E is erroneously perceived as a "mere clump of cells", so no biggy.
And, of course, all this new embryo incubator hi-tech will be very expensive, I would imagine. Someone has to pay for it. That adds to the challenge.
Then again, if scientific technology had pushed viability back to more earlier stages of gestation, those who simply sought non-medical reason abortion at a stage of pregnancy at or past gestation would be denied by legitimate state interest in protecting prenatal life. That opens up a whole 'nother can a worms, as where will we put all these new infants undesired by their birth mothers who were forced by law to carry them to term or, if they could afford it, transfer to an embryonic incubator? Hopefully there will be good adoptive parents available .. but who knows.
Ultimately, the best thing to do is to find better ways than presently available to
prevent creation of undesired conceptions.
That really is the
preferred solution to the inevitability of a greatly pushed back age of viability.
