Low testis weight and sperm count in Kdm3atm1Jxu/Kdm3atm1Jxu mice

reproductive system
increased male germ cell apoptosis ( J:159956 )
• group B germ cells (pachytene, diplotene, and secondary spermatocytes) and group C germ cells (round and elongating spermatids) exhibit a 5- and 10-fold higher rate of apoptosis, respectively, than in wild-type mice
oligozoospermia ( J:159956 )
• mice exhibit severe oligozoospermia with nearly no mature spermatozoa observed in the apical crypts of Sertoli cells or in the lumen of seminiferous tubules unlike in wild-type mice
abnormal spermatid morphology ( J:159956 )
• at steps 13 to 15, spermatids are short, irregular, and polygonal unlike in wild-type mice
abnormal spermiogenesis ( J:159956 )
• spermatid elongation is blocked unlike in wild-type mice
