  • The effect of age on outcome is one of the most intriguing areas in the assisted reproduction field. In older patients using donor spermatozoa to reproduce, it remains undefined as to which is the treatment of choice: intrauterine insemination (IUI) or IVF/intracytoplasmic sperm injection (ICSI). Since life-table analysis provides data that are easy to use for patient counselling, this study analysed cumulative delivery rates (CDR) in patients using donor spermatozoa undergoing either primarily IUI or IVF/ICSI and patients who eventually switched from IUI to IVF/ICSI. Crude and expected CDR after six IUI cycles and three primary ICSI cycles (no previous IUI) were similar in both groups (24% versus 26% and 29% versus 35%, respectively). Since time-to pregnancy is an important factor in these older patients, ICSI treatment is advised to be started immediately, since a single cycle of ICSI will achieve the same success rate as a much longer period with at least six IUI cycles. If patients switch to ICSI after failed IUI, this only adds marginal benefit in CDR. Nearly all deliveries in the primary ICSI group were achieved in the first cycle.
