Maybe countries could tackle such problems twofold:

- first, implement a nationwide social freezing program, where women in their 20s are offered to freeze their eggs at a young age for free. Such a large-scale program would probably also improve the tech and might make egg collection less intrusive.

- combined with this program, let the women who freeze their eggs opt-in into an egg donation program, where some of their eggs can be used by women with fertility problems

But as with many things fertility, seems that modern states simply do not have the capacity to seriously try anything. Who knows why that is.

They might also look to Israel to see what they're doing that's working so much better than other OECD countries - see my other comment in this post.

But Israel's advantage seems to be partly cultural and I don't see any time-limited elected government willing to expend that much effort to change their nation's culture.
