Abstract

Abstract: There is no evidence for the superiority of conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) using donor oocytes. This retrospective descriptive study aimed to compare the outcomes of conventional IVF ( n = 506) and ICSI ( n = 613) with donor oocytes in ( n = 968) normozoospermic patients. Although the fertilization rate was statistically higher in the ICSI group ( p < 0.001), conventional IVF provided better results than ICSI with respect to embryo quality (number of grade A embryos, p < 0.001). In addition, we observed more blastocysts in the conventional IVF group ( p < 0.001) and more good quality embryos were obtained for cryopreservation compared to ICSI ( p < 0.001). Regarding clinical results, there were no statistical significant differences in the positive pregnancy test, clinical pregnancy and clinical miscarriage rates between IVF and ICSI. However, the implantation rate was statistically higher when IVF was performed (50.4% vs. 43.0%, p = 0.031, OR (95% CI): 1.185 (1.050–2.530)). In conclusion, with the use of normozoospermic samples in our oocyte donation programme, IVF offers more embryo efficiency and increased implantation rates than ICSI.
