reproductive system
• males show reduced caudal epididymal sperm counts
• more than 70% of sperm are abnormal
• malformation of sperm flagella, including disorganized outer dense fibers and the axonemal microtubules
• disorganized outer dense fibers

• total motility of sperm is reduced
• males are sterile
• however, gross testes morphology, body weight and testis weight are normal
