  1. Absolute testes weight (g), daily sperm production, and sperm content per gram of testes in Brown Norway rats at week 12 following a 5-week exposure to 20 mg/m3 of GMA-SS, and at week 24 following a 12 week recovery period. Mean ± standard error (n = 6–12). Significant effects are highlighted in bold
