A study by the Universities of Bristol and Glasgow found that about two thirds of couples will be successful following six or more cycles of IVF
Couples using IVF should anticipate needing at least six cycles, scientists from Bristol University say, as they call on the NHS to increase free treatment courses.
A study by the Universities of Bristol and Glasgow found that 65.3 per cent of patients – about two thirds – will be successful following six or more cycles of IVF.
Researchers now suggest that the number of IVF cycles per patient should be extended beyond the usual three or four embryo replacements.
IVF is commonly stopped after three or four unsuccessful embryo transfers, with three unsuccessful transfers labelled “repeat implantation failure”.
The research, by the Universities of Bristol and Glasgow, is published in The Journal of The American Medical Association today.
