South Korea's local governments are facing rapidly escalating financial and administrative pressure as the central government continues to expand infertility treatment support under its broader campaign to address the country's persistently low birth rate without providing matching funding to the municipalities now responsible for delivery.

Data submitted by the Ministry of Health and Welfare to Rep. So Byeong-hoon of the Democratic Party of Korea reveal the scale of the shift. Local government budgets for infertility treatment subsidies rose 149.6% from 67 billion won ($49 million) in 2021 to 167.2 billion won in 2025, an increase of 100.2 billion won over four years, bringing the total to approximately 2.5 times its 2021 level.

How the Programme Reached Local Government and Kept Growing

National health insurance has covered infertility treatment in South Korea since October 2017. Separately, a subsidy programme designed to help patients cover out-of-pocket costs and expenses not covered by insurance was transferred from the central government to local governments in 2022.

The transfer, however, did not come with a freeze on policy expansion. The central government continued to broaden the scope of the programme even as municipalities took on the administrative and financial responsibility for running it.

The expansions came in quick succession. In January 2024, income eligibility requirements were abolished across all 17 provinces and metropolitan cities, a move that broadened the pool of eligible recipients significantly. The following month, February 2024, local government support was extended to cover up to 25 treatment cycles per patient, comprising up to 20 IVF cycles and five artificial insemination cycles. Then in November 2024, the National Health Insurance coverage framework was revised: rather than capping support at 25 cycles per infertile couple, coverage was changed to allow up to 25 cycles for each successful pregnancy resulting in childbirth, materially increasing the total number of cycles that could be funded. The same revision lowered the health insurance copayment rate for women aged 45 or older from 50% to 30%.

Each of these changes increased demand and cost. The municipalities were responsible for funding the difference.

The Ministry's Response: Awareness Without Accountability

When asked to account for the financial impact of these expansions on local governments, the Ministry of Health and Welfare acknowledged that the policy changes could impose additional burdens. But it said it does not separately track the actual increase in local government spending attributable to its policy decisions, nor does it monitor which municipalities have had to allocate supplementary budgets to cover funding shortfalls.

The ministry said such matters are left to individual local governments to manage.

Local Governments Speak Out

The mismatch between central policy-setting and local funding responsibility has prompted a growing chorus of concern from municipalities across the country.

The Busan Metropolitan Government described infertility treatment subsidies in a written opinion submitted to Rep. So's office as a programme serving a national policy objective, not a local one.

"The expansion of national policies and growing demand are increasing not only local governments' financial burden but also their administrative workload and staffing needs for applications, management and settlement."

Busan called for the programme to receive central government subsidies and urged the government to establish a cost-sharing system that would automatically link future policy expansions to additional central government funding.

The Daejeon Metropolitan Government similarly called for additional financial support, citing the sharp budget increases driven by guideline revisions and rising demand. It urged the government to either return responsibility for the programme to the central level or extend financial support for transferred programmes.

Gyeonggi Province and South Chungcheong Province sought additional budget support as early as 2022, the first year after the transfer. Sejong and Incheon formally called for the programme to return to central government funding in 2025.

In September 2025, five provincial and metropolitan governments, Incheon, Daejeon, Gyeonggi, South Jeolla, and South Gyeongsang, jointly requested that the infertility treatment subsidy programme and the maternal and newborn health care programme both receive central government subsidies.

An Independent Assessment: Infertility Is a National Issue

The National Assembly Budget Office identified the infertility treatment subsidy programme as a key concern in its 2023 report evaluating fiscal decentralisation policies and programmes transferred to local governments.

"Since the transfer to local governments, differences in their financial conditions have resulted in regional disparities in support benefits. Infertility is a national issue rather than a regional one, and national-level management should be strengthened to ensure balanced services for the public."

That assessment cuts to the centre of the problem: when access to infertility treatment support depends on where a patient happens to live, and where that location determines how generously funded the local subsidy is, the result is a system that delivers unequal outcomes for a condition that knows no regional boundaries.

The Political Challenge

Rep. So Byeong-hoon put the accountability question plainly:

"It is not reasonable for the central government to take credit for the results of expanded policies while local governments shoulder the resulting financial and administrative burdens."

"What matters most is ensuring that infertile couples can reliably receive the support they need regardless of where they live. The central government should take responsibility so that people desperately hoping to have children do not face disparities in support depending on the financial conditions of their place of residence."

The policy challenge South Korea now faces is structural. A programme designed to address a national demographic crisis, the country's low birth rate, has been expanded at the national level while its costs have been devolved to localities with varying fiscal capacity. The result is an infertility treatment support system that is both growing in ambition and increasingly uneven in delivery.

Whether the central government moves to reclaim funding responsibility or establishes a formal cost-sharing mechanism tied to future policy changes will determine whether the expansion of support for infertile couples in South Korea translates into genuinely equitable access, or into a widening gap between what the system promises and what patients in different cities and provinces actually receive.
