> This will enable older women to have kids and solve some reproductive issues. Under 35, the success rate for IVF is ~40%. Between 35 and 42, it's about 10%. After 42 it's about 4%. Each time you try it costs around 20k, albeit sometimes the first one or two tries are subsidized by insurance or state grants. And there are also all sorts of health risks to both the mother and baby. So even if you can safely create unlimited eggs at a nominal cost, I don't see this having any practical effect on family planning. (Other than as a treatment for certain infertility issues.) Given that it takes around two years to have a baby, pragmatically you're still going to ideally want to start having kids no later than 35 - 2 * (desired kids), at least for the foreseeable future.
