The presented study examined the potential effects of celery leaf extract on spermatogenesis in diabetic male rats.  Methodology: Twenty-four male rats total were used in the study; they were split into three groups of eight rats each: Control group: Every day, one milliliter of distilled water was given to normal rats.  Group with diabetes: Every day, 1 ml of distilled water was also given to diabetic rats.  Group receiving celery extract: For thirty days in a row, diabetic rats received a daily dose of 200 mg/kg of celery extract. Results: Sperm count and seminiferous tubule diameter were significantly higher in the group receiving 200 mg/kg of celery extract compared to the control group. Testicular Volume and Organ Weights: Additionally, the treated group showed a significant increase in the vas deferens, epididymis, and testis testicular volumes and weights.  Lipid profile and glucose: Celery extract had a notable impact on glucose and triglyceride levels in diabetic rats. Liver enzymes: The extract markedly raised the levels of the liver enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Conclusion: These findings imply that celery juice extract may be advantageous for a number of diabetic male rat parameters, including spermatogenesis, liver enzymes, lipid profiles, glucose concentrations, and reproductive parameters.  This suggests that celery may help to improve male fertility and prevent complications from diabetes.  Nevertheless, additional investigation is required to clarify the fundamental processes accountable for these impacts and validate the findings.
