Patients with azoospermia need donor sperm as a means to conceiving. However, to proven to be HIV-negative, donated semen need to be frozen and quarantined for 6 months before release for use. Therefore, intracytoplasmic sperm injection (ICSI) is a common clinical practice to ensure fertilization. According to the study in our hospital from 2004 to 2010, we found that when using qualified frozen sperm, higher fertilization rate was obtained by ICSI (80.8 ± 1.7%, p <0.01) as compared by conventional IVF (66.4 ± 2.4%). However, the yield of good quality embryos was higher in IVF (64.1 ± 3.4%, p = 0.022) as compared to ICSI (55.9 ± 3.0%). Therefore, conventional IVF is feasible for better embryo quality when using frozen sperm clinically, however, for the patients with low egg number, ICSI could be an alternative to ensure enough fertilization rate for embryo transfer.
