Introduction Semen quality, characterized by parameters such as sperm count, motility, and morphology, determines successful fertilization and subsequent embryo health. This study investigates the impact of sperm parameters on embryo quality in assisted reproductive technology (ART). Methods The study utilized a retrospective design with 194 male and 194 female participants who underwent fertility treatment from October 2020 to May 2024. Semen analysis included assessment of sperm count, motility, and morphology. Embryo quality was evaluated on days three and five post-fertilizations based on morphological criteria. Statistical analyses, including one-way ANOVA and chi-square tests, explored relationships between semen parameters and embryo quality. Results The study included 388 participants (males: 194 and females: 194). Female participants had a mean age of 31.0 ± 4.6 years and a mean BMI of 23.1 ± 5.3 kg/m², while males had a mean age of 36.6 ± 5.4 years and a mean BMI of 22.7 ± 2.8 kg/m². Paternal age and BMI showed no significant association (p > 0.05) with embryo quality. However, sperm quality parameters such as sperm count, motility, and morphology demonstrated significant associations (p < 0.05) with embryo quality on both day three and day five, indicating that abnormal sperm parameters were linked to poorer embryo quality. Factors such as alcohol consumption, smoking, tobacco use, living in industrial areas, and tea/coffee consumption showed no significant association with embryo quality. Conclusion The findings of the study emphasize the importance of comprehensive semen analysis in fertility assessments and highlight opportunities for improving ART outcomes through targeted interventions and further mechanistic research.
