Abstract

To investigate the clinical outcomes of conventional IVF and ICSI in female patients aged 40 years and over with no more than five oocytes retrieved and non-male factor infertility.A retrospective study of a cohort of 644 patients undergoing IVF/ICSI treatment. The 534 female patients aged ≧ 40 years with no more than five oocytes retrieved and non-male factor infertility undergoing their first conventional IVF cycles were assigned in IVF group. The rest of 110 patients aged 40 years and over with no more than five oocytes retrieved and non-male factor infertility undergoing first ICSI cycles were recruited in ICSI group.Our results showed the clinical pregnancy, live birth and miscarriage rates were similar between the IVF and ICSI groups (21.59% vs. 13.25%, P > 0.05; 12.16% vs. 6.02%, P > 0.05; 43.68% vs. 54.55%, P > 0.05; respectively), however, the implantation and cumulative live-birth rates were significantly higher in the IVF compared to the ICSI group (15.11% vs. 7.75%, 14.59% vs. 5.56%, P < 0.05), though the IVF group had a lower normal fertilization rate (61.56% vs. 76.00%, P < 0.001).Our study provides strong evidences that the conventional IVF exhibits advantages over the ICSI method in non-male factor infertility for advanced age patients with five or fewer oocytes retrieved.
