Assisted reproductive technology has enabled many couples to fulfil their dreams of having a family. However, the success rate of treatments involving this technology declines rapidly when women enter their thirties. The chances of a woman having a live baby through IVF are also related to the reasons for infertility and the nature of the treatment received. This paper draws on data from the Fertility Decision Making Project to examine views regarding the use of IVF held by men and women in their twenties and thirties who were in a committed relationship. Sociodemographic factors linked with respondents' beliefs about their preparedness to use IVF and its likely success are examined.
