N normal phenotype
endocrine/exocrine glands
abnormal seminiferous tubule morphology ( J:95901 )
• the number of spermatozoan-containing tubuli per 100 tubuli is significantly reduced
small seminiferous tubules ( J:95901 )
• tubule diameter is slightly but significantly reduced

reproductive system
oligozoospermia ( J:95901 )
• sperm count is reduced by 60% compared to wild-type littermates; however, sperm motility is normal
