characteristics, social and familial environment, food consumption and habits, tobacco
and alcohol use, physical activity, libido and quality of life (surveys))
- Clinical examination and anthropometric assessment (BMI, blood pressure, expired CO)
- Blood samples (Metabolic and nutritional plasmatic biomarkers ; Plasmatic oxidative
stress biomarkers ; antioxidants micronutrients ; hormones of adiposity and inflammation
; sex hormones ; persistent contaminants)
- Sperm sample (sperm count-morphology ; DNA fragmentation ; CASA)
Bariatric surgery
Second visit (6 month follow-up)
