A large international study presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE) reports a strong association between reduced fertility treatment costs for patients and increased births achieved through assisted reproductive technology (ART). Across the sources, the key finding is that halving patients’ out-of-pocket costs for fertility treatment is linked with a 2.67-fold increase in births resulting from ART. The results are described as coming from a worldwide, large-scale study presented at the meeting in London on July 6, 2026. The reporting frames the relationship in terms of patient affordability: when patients face about half the direct costs they previously paid, the number of ART-related births increases by a factor of 2.67, according to the study’s analysis. The sources do not provide additional methodological details, the specific cost calculation approach, or whether the study proves a direct causal mechanism. Instead, they summarize the observed association and its magnitude, emphasizing the potential impact of cost reduction on ART outcomes as discussed at the ESHRE meeting.
