• Conducted a randomized trial with male participants
• Assessed hormonal levels and metabolic markers pre- and post-intervention
• Analyzed dietary intake of ultra-processed foods
• Significantly increased fasting insulin levels (mean difference 5.2 μU/mL, 95% CI 2.1 to 8.3, p=0.003) with high ultra-processed food intake
• Notable decrease in testosterone levels (mean reduction 50 ng/dL, 95% CI 20 to 80, p=0.002)
• Observed adverse effects on sperm quality (percentage of motile sperm decreased by 15%, p=0.01)
