What is the role of assisted reproduction technology in the management of age-related infertility?

Abstract

Although in the UK the upper age limit for National Health Service (NHS) provision of in vitro fertilisation (IVF) is 39 years of age there has been an increase in number of women having fertility treatment in their 40s. However, the success rates of IVF and intra-uterine insemination (IUI) in this group remain low. Human Fertilisation and Embryology Authority (HFEA) data from 2006 showed that the live-birth rate from IVF in the UK was 11% in the age group 40–42, 4.6% in the age group 43–44 and less than 4% in women over 44. We performed a literature search for studies using terms and combinations of terms in online databases and published meta-analyses reporting the outcome of interventions in older women. This review showed that assisted reproduction technologies (ARTs) continue to have low live-birth rates in women over 40. Trials showed that assisted hatching may increase the chance of pregnancy in women with poor history. Blastocyst transfer is associated with better outcome, whereas application of pre-implantation genetic screening (PGS) in older women has not increased the success rates. It appears that, with the exception of egg-donation, ART has no answer yet to age-related decline of female fertility.
