The purpose of this study was to contribute to the development of strategies to obtain acceptable outcomes in assisted reproduction treatments in women over 40 years of age. A retrospective study was carried out on the database of the German Hospital in Istanbul using data from the years 1997 to 2004. A total of 1114 embryo transfer cycles were assessed. The pregnancy, implantation and delivery rates of the assessed population were 18.2, 8.3 and 10.9% respectively. The results showed that the demographics and outcome of cycles of women at 40 years differed significantly from those over 40. Cycles in which six or more oocytes were retrieved displayed better characteristics and outcome than those with five or fewer. The clinical pregnancy and delivery rates after transfer of three embryos were similar to four or more. Therefore, women over 40 years with a good ovarian response and at least three embryos available for transfer have an acceptable pregnancy and delivery rate with a low multiple pregnancy risk.
