Roughly ~22% (can't tell due to the graphical nature) responded "Struggling to conceive".
If you have a full FIFTH of your population willing but not able to have children, that's a lower hanging fruit to pick than somehow incentivising people who don't want to have children to change their mind.
Fertility treatment is almost never brought up... as though it were taboo. That needs to change. The cost of an IVF cycle is somewhere around $20,000 USD. It's a huge cost to bear as an individual, it's a drop in the bucket for a government, and pays for itself many times over when the conceived child enters the workforce.
