This study was conducted to evaluate the current results of standard in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in the elderly (≥ 40 years of age) female population. Oocyte recovery, fertilization, embryo transfer, pregnancy and cumulative pregnancy rates were assessed. The results were analyzed for: the entire elderly population; the standard IVF group (group 1); all those in the ICSI group (group 2); and ICSI for severe male-factor category (group 3). A total of 330 IVF and 158 ICSI treatment cycles were carried out in 249 women. Forty-five (9.2%) clinical pregnancies were achieved. This rate was not statistically different from those achieved for groups 1, 2 and 3 (9.1%, 9.5% and 6.8%, respectively). The cumulative pregnancy rate for a total of five cycles was 19.2% and 26.4% for groups 1 and 2, respectively. For those who started their treatments at ≥ 40 years, the cumulative pregnancy rate for three cycles was 26.5% and 36.5% in groups 1 and 2, respectively. These results clearly demonstrate that female age is a major success determinant, with similar influence on both standard IVF and ICSI therapy modalities.
