reproductive system
oligozoospermia ( J:301832 )
• at 8 and 12 weeks of age
teratozoospermia ( J:301832 )
• aberrant spermatogenic cells are seen starting at 6 weeks of age
abnormal spermatid morphology ( J:301832 )
• few elongated spermatids are seen at 8 weeks of age
• by 12 weeks of age round spermatids are nearly absent
small testis ( J:301832 )
• testes size gradually decreases with age and by 12 weeks of age testes are significantly smaller compared to wild-type controls
abnormal spermiation ( J:301832 )
• premature release of germ cells from the seminiferous epithelium
male infertility ( J:301832 )
• males are infertile despite displaying normal mating behavior
