I would imagine there are far more expensive medically necessary treatments than fertility that could be watched in terms of expanding budgets, like heart disease, diabetes etc. And plenty of babies for whatever reason can spend time in the NICU, not just from older parents and those with health issues.
For those who require it and for those that manage to meet the criteria for some state funding then I wish them well and that the budget does indeed expand to meet the needs and help more families with these medical costs.
