Sperm DNA fragmentation and its association with semen parameters in male infertility: A cross-sectional study.

This article focuses on the relationship between sperm DNA fragmentation (SDF) and conventional semen analysis parameters in assessing male infertility among Lebanese men. The study of 86 infertile males found no statistically significant correlation between high SDF rates—defined as DNA damage exceeding 20%—and abnormal semen parameters such as oligospermia, asthenospermia, teratospermia, pH, vitality, or leukocytospermia, nor with demographic factors including age, obesity, and tobacco use. These results suggest that semen analysis alone may not fully capture sperm DNA damage, highlighting the potential importance of SDF testing as an independent diagnostic tool in male infertility evaluation. The authors note limitations including sample size and study design, and recommend further research to clarify the clinical utility of SDF assessment.
