The success rate of IVF has significantly improved over the last decade.

Abstract

AIM: To demonstrate that success rates with in vitro fertilisation (IVF) have been improving despite decreasing the number of embryos transferred. MATERIALS AND METHODS: This was a retrospective cohort study comparing live birth outcomes for women who started IVF between 2001 and 2005 with women who started between 2006 and 2010, using life table analysis to allow for the fact that women had differing number of cycles of treatment. The data were obtained from a single IVF centre, Monash IVF Geelong, Victoria. The 2001-2005 cohort consisted of 233 women, and the 2006-2010 cohort consisted of 453 women who started IVF between the specified dates. The main outcome measure was a live birth. Life table analysis was used to estimate the cumulative probability of a live birth after each cycle.
