Abstract

In Vitro Fertilization (IVF) offers infertile couples the opportunity to have a baby. Many of these couples have multiple attempts to try to achieve this goal. To model the risk factors that affect the process at any of its stages, across the multiple attempts, an ordinal response and an extended continuation ratio random effects model have been used. This enabled the modelling of differential effects of covariates on different stages of the process. A significant random effect suggests that there is a couple specific effect, which may be interpreted as a fertility index.
