endocrine/exocrine glands
decreased testis weight ( J:35110 )
• testes of adult mutant males were significantly lower in weight as compared to heterozygous and wild-type controls
• epididymal and seminal vesicle weights were comparable to controls

reproductive system
abnormal male meiosis ( J:35110 )
• most seminiferous tubules contained pachytene spermatocytes with condensed nuclei, some of which appeared fragmented and apoptotic

arrest of spermatogenesis ( J:35110 )
• mice were deficient in postmeiotic spermatids and lacked spermatozoa in the epididymis
