Objective: Intracytoplasmatic sperm injection (lCSl) described by Palermo et al. in 1992 has dramatically changed the treatment of severe male factor infertility. Many doubts about the spermatozoa quality have appeared, because of that the spermatozoa morphology became extremely important in the semen evaluation. Generally the sperm morphology analysis is done before the procedure and let us to think if the sample obtained in the ICSl day would be value different. The objective of this work is to determine the correlation between spermatozoa morphology and embryo quality when the sperm samples analysis was realized in the same day of ICSl procedure. Material and Methods: This study included 71 patients who underwent our lCSl cycles from May to August 2000. ln all cases were realized the sperm morphology analysis on the lCSl day according to Krüger Strict Criteria. Slides with 10µl of fresh and liquefied semen were done to analyze the sperm morphology. Results: The semen samples of 71 patients were analyzed and compared with embryonic classification by VeecK (1991). Our results showed that seminal samples with poor sperms parameters produced, in the most of times, bad quality embryos. Conclusion: The analysis of these results allow us to conclude that spermatic morphology using Krüger Strict Criteria in the day of the therapeutic procedure has influence in embryo quality.
