reproductive system

multinucleated giant male germ cells ( J:255310 )

♂ • multinucleated giant cells are present in the testis cords and are first detected at P21

♂ • multinucleated giant cells often contain more than 4 nuclei

small testis ( J:255310 )

♂ • average length is about 72.4% of wild-type or heterozygous controls

abnormal spermatogenesis ( J:255310 )

♂ • a significant number of haploid germ cells are precociously released

azoospermia ( J:255310 )

♂ • epididymal tubules appear devoid of sperm

abnormal spermatid morphology ( J:255310 )

♂ • Golgi bodies appear smaller and docking of the basal body and attachment of the acrosomal vesical to the nucleus are absent in round spermatids

arrest of spermiogenesis ( J:255310 )

♂ • arrest at the round spermatid stage

♂ • fail to progress beyond step 3 of spermiogenesis

male infertility ( J:255310 )

♂ • males exhibit normal mating behavior but fail to impregnate their partners

♂ • female fertility is normal

cellular
