Objective: To evaluate if ICSI outcome are influenced by the number of cycles and oocyte injected per day. Methods: Data of ICSI cycles performed in an unselected infertile population were included. The influences of the number of cycles and number of injected oocytes on the ICSI outcomes (fertilization rate, high quality embryos rates on day 3 of development, blastocyst formation rate, the proportion of cycles with embryo transfer, pregnancy rate and implantation rate) were investigated. Results: Regression analyses results showed no significant influence of the number of cycles and oocytes injected per day on the ICSI outcomes (Table 2 and 3, respectively). Conclusions: The outcomes of ICSI are not influenced by the number of cycles or the number of oocytes injected per day. We suggest that an appropriate number of embryologists per cases per year guarantee successful outcomes independently of the daily workload.
