Aim: This study was carried out to assess the outcome of the intracytoplasmic morphologically selected sperm injection (IMSI) technique compared with the previous failed intracytoplasmic sperm injection (ICSI) attempts in oligoasthenoteratozoospermia (OAT)/severe OAT (SOAT)/teratozoospermia patients. Setting: Institution-based, in vitro fertilization center. Study Design: It was a nonrandomized prospective study including 57 couples who had previous one or two ICSI failures (failure due to no implantation as embryos were transferred in these cycles and had no pregnancy) due to male factor. There was no case of total fertilization failure. IMSI was carried out in these couples and the results were compared with their previously failed ICSI attempts. Materials and Methods: Real-time selection of sperms was done using IMSI as it allows the assessment of fine nuclear morphology and vacuoles in the sperm head at a high magnification (>6000×) with differential interference contrast optics. Therefore, IMSI was applied in couples having OAT, SOAT or teratozoospermia as male factor and the results were compared with their previous failed ICSI attempts. Statistical analysis was carried out using GraphPad Prism. Results and Conclusion: Data analysis demonstrated significant difference in the fertilization rate between IMSI and previous ICSI attempts of these patients (30.0% vs. 52.0%; P < 0.05). The embryo quality, implantation and pregnancy rates with IMSI were also significantly higher than those of their previous ICSI cycles (32% vs. 56.4%; 30.2% vs. 68.5%; 0.0% vs. 62.4%; P < 0.05). Our conclusion is that the IMSI procedure improved embryo development and the clinical outcomes in the same infertile couples with male infertility and poor embryo development over their previous ICSI attempts and can be taken up as the treatment of choice in cases of severe male factor infertility.
