• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

reproductive system

arrest of male meiosis ( J:140803 )

• spermatogenesis does not proceed beyond meiosis prophase

abnormal seminiferous tubule morphology ( J:140803 )

• mice exhibit greater thickening and hyperplasia of peritubular myoid cells compared to Ar^Tfm male mice on the original stock background

enlarged seminiferous tubules ( J:140803 )

• in 8 of 31 mice unlike Ar^Tfm male mice on the original stock background

increased Leydig cell number ( J:140803 )

• unlike Ar^Tfm male mice on the original stock background

increased testis weight ( J:140803 )
