ABSTRACT
OBJECTIVE: The aim of this study was to evaluate the efficiency of the intracytoplasmic morphologically selected sperm injection (IMSI) technique compared with conventional ICSI and previous ICSI attempts in oligo-astheno-teratozoospermia (OAT) patients. METHODS: The sperms were selected under high magnification (6,600x) and used to induce fertilization in previous ICSI patients by IMSI. These results were compared with previous conventional ICSI cycles in patients with OAT infertility. RESULTS: These results demonstrated no significant difference in the fertilization rate between IMSI and previous ICSI cycles (67.7% vs. 65.0%). However, the pregnancy and implantation rates with IMSI were significantly higher than those of the ICSI cycles (33.3% vs. 12.5% and 14.6% vs. 5.4%, respectively; p<0.05). The miscarriage rate among pregnant patients (18.2% vs. 37.5%) showed no statistically significant difference between groups. CONCLUSION: Compared to conventional ICSI, this study found that IMSI increased the IVF-ET success rates in patients with OAT.

Objective To observe the change on living blood cells of peripheral bloodstream in patients with TIA.Methods To observe the behavior of living blood cells in the peripheral bloodstream of 18 patients with TIA using high magnification microscopy system, and compared with 20 healthy individuals.Results Erythrocyte aggregation rate, leukocyte activation rate, thrombocyte activation rate, and the extent of those changes were higher in the TIA group than in the control group. This difference was statistically significant ( P
