Abstract
OBJECTIVE: To determine whether intracytoplasmic sperm injection (ICSI) could prevent total fertilization failure (TFF) and enhance the embryo quality in patients with non-male factor infertility. STUDY DESIGN: A total of 296 in vitro fertilization (IVF) cycles performed in patients with non-male factor infertility between April 2009 and March 2013 were included in this retrospective study. During the period, ICSI and conventional IVF were performed in 142 and 154 cycles, respectively. The usual indications for ICSI were in the cycles of patients with (1) known low fertilization rate, (2) repetitive implantation failure, (3) advanced maternal age, (4) presence of endometrioma, (5) low oocyte yield (number of oocytes ≤3), or (6) poor quality oocytes. The rate of TFF, normal fertilization, abnormal pronuclei (PN) formation, embryo quality, and pregnancy outcomes between the patients treated with ICSI and conventional IVF cycles were compared. RESULTS: The patients treated with ICSI (ICSI group, n=142) presented fewer number of oocytes than patients treated with conventional IVF cycles (n=154). The TFF rate was not different (4.2% vs. 0.6%, P=0.059), but the ICSI group presented a significantly higher rate of normal fertilization (83.4% vs. 79.1%, P=0.04) and lower rate of abnormal PN formation (3.9% vs. 13.3%, P<0.01). The cleavage stage embryo quality was better in the ICSI group (grade A: 31.1% vs. 21.3%, P=0.001; grade A+B: 65.1% vs. 47.6%, P<0.001). CONCLUSION: The result of this study does not support the use of ICSI to prevent TFF in patients with non-male factor infertility. However, ICSI improved the fertilization rate and the embryo quality.
