| Περίληψη: | Delayed childbearing in advanced economies has increased reliance on assisted reproductive technologies (ART). Yet, how ART and especially donor egg treatments contribute to population-level fertility rates remains under-studied. Analysing all ART treatments in the UK (1991-2018), we document rising ART usage: ART-conceived births contributed 3.0 per cent to the total fertility rate in 2018 and 14.9 per cent to fertility rates among women aged 45-50. ART success rates show a clear age-related decline when using women's own eggs but remain consistent across age groups when using donor eggs. Consequently, from age 43 onwards, ART-conceived births result predominantly from donor egg treatments. Our findings indicate that fertility recuperation at advanced ages is unlikely to succeed with ART using a patient's own eggs; egg donation and egg freezing appear indispensable for supporting fertility at advanced ages with ART. This has significant implications for public health communication, as this fact is not widely known. |
