Minimising twins in in vitro fertilisation: a modelling study assessing the costs, consequences and cost-utility of elective single versus double embryo transfer over a 20-year time horizon

Abstract

Considering the high twin pregnancy rate associated with DET, coupled with uncertainty surrounding QALY gains, eSET is likely to be the preferred option for most women aged ≤ 36 years. The cost-effectiveness of DET improves with age, and may be considered cost-effective in some groups of older women. The decision may best be considered on a case-by-case basis for women aged 37-39 years.
