I think it's a good thing, and the Frankenstein type concerns are no more than fear a baby will have trauma from being conceived by IVF and briefly in a test tube. I'd be happy for a women without one to have my womb after I died, I have had infertile friends and the impulse that I wished I could do something to help.
However, I'm already very medicalised, I've had lots of lifesaving surgeries and take strong medication. So this doesn't feel as big a step as it might for a healthy person for whom everything goes to plan. My medication and pregnancy were managed, medically, nobody suggested I should have a baby at all.
The only downside I can see is that I think endless options can prevent acceptance. I'm not sure we, as a population of women, are happier since IVF. Some individually are, but some have taken a financial hit and spent years holding on to a sliver of hope rather than moving on. If this became something else for desperate people to pin their hopes on,I can see a lot of people wasting their 30s and 40s. Hopefully it will only be for people with no other option rather than added to the infertility pathway.
