“…Kim et al suggested no difference in implantation and fertilization rates between the IVF and ICSI procedures (Kim et al, 2007). The same results were observed by Xi and associates (Xi et al, 2012). Consistent with our study, Bhattacharya et al argued that ICSI is only more effective for severe male infertility and it has no better effect on female infertility than IVF (Bhattacharya et al, 2001).…”

Background: Assisted Reproductive Techniques (ART) have been used for addressing numerous causes of infertility. However, it remains unclear which kind of these methods are best for various infertility types. Accordingly, this study aimed at determining pregnancy success rates by different ART in tubal, ovarian, and sperm disorders. Methods: The present descriptive retrospective study used the records of individuals who had referred to the Infertility Center of Kerman University of Medical Sciences from March 2016 to December 2017. All subjects underwent Intracytoplasmic Sperm Injection (ICSI) and In Vitro Fertilization (IVF). The sperm parameters were assessed based on the criteria of the World Health Organization (WHO) for determining the causes of male infertility. The data were documented and compared with the criteria of the WHO. Then, they were analyzed by analysis of variance, Paired Samples t-test, Chi-squared, or Fisher’s Exact tests using SPSS. Results: The overall Mean±SD fertility rate in IVF and ICSI was 4.28±2.87 and 3.62±2.54, respectively and the difference was not significant (t=1.02, P=0.319). There was a significant difference in the fertility rate due to tubal infertility (P=0.018) between ICSI and IVF; the fertility rate in the IVF method was significantly higher than that of the ICSI. The pregnancy rate in the freeze method was higher than those of the other methods (P<0.001). This discrepancy was also found in all causes of infertility. There was no significant difference in the disorders of sperm and the result of two methods (IVF/ICSI). Conclusion: The obtained results suggested that in the freeze method, the pregnancy rate was higher than other approaches; this discrepancy was found in all the causes of infertility. It is suggested that frozen-thawed embryo transfer be used in infertile individuals. This is because it increases the success rate of pregnancy and prevents complications due to the repeated use of infertility treatments and exorbitant treatment costs.

“…As rescue ICSI was performed for patients with <4 retrieved oocytes was only carried out in groups 1 and 3 (when the IVF rate was >33%), and some studies reported that rescue ICSI performed in these groups will not produce good treatment outcomes (Xi et al, 2012); therefore, cycles with <4 retrieved oocytes were not included in the grouping. For all the 313 cycles analysed in this study, the samples had >4 retrieved oocytes, were gathered in our centre from 2011 to 2013, had a conventional IVF rate of <50%, and underwent rescue ICSI.…”

To explore the need for rescue intracytoplasmic sperm injection (ICSI) in cases of partial fertilisation failure during a conventional in vitro fertilisation cycle, rescue ICSI was performed for cycles with a fertilisation rate of <50%. The data were divided into three groups based on the fertilisation rate: group 1 (0%), group 2 (<25%) and group 3 (>25%). The impact of rescue ICSI on each group was then analysed in terms of ovum fertilisation, embryo development, embryo utilisation and selection of embryos for transfer. Rescue ICSI was performed on 1831 unfertilised oocytes from 313 cycles. The fertilisation rates for group 1, group 2 and group 3 were 74.66, 68.35 and 65.46%, and the rate of polyploidy in the three groups was 8.55, 11.33, and 14.47%. The percentage of embryos that can be transferred from rescue ICSI for group 2 was 38.33%, and this value was higher than those of the other two groups. It is concluded that rescue ICSI is not recommended for patients with an IVF rate of >25% as the procedure is associated with a greater risk and low returns. However, it is feasible to perform rescue ICSI for patients with IVF rates of <25%.
