摘要：

Objective: This study aims to investigate whether alterations in sperm DNA fragmentation rates are more frequent when Kruger strict morphology is >= 4% (normal). Methods: The retrospective study included 132 participants from March 2020 to November 2021. Participants were divided into two groups based on the inclusion criteria: normal and abnormal Kruger strict morphology, with a mean age of 40 years. Seminal analyses were conducted following the guidelines outlined in the 6th edition of the Manual for Examination and Processing of Human Semen (2021). The sperm chromatin dispersion test was used. Results: The results did not reveal a statistically significant difference between Kruger strict morphology and Sperm DNA Fragmentation Index correlation (p<0.05) between the normal and abnormal morphology groups (p<0.05) and in Seminal Parameters. Sperm concentration is lower when Kruger strict morphology is < 4% (abnormal) (p=0.007). Conclusions: In conclusion, abnormal Kruger strict morphology does not have a higher predisposition to increased sperm DNA fragmentation.
