摘要: Abstract Silver fox and blue belong to different genera, the hybrid males are reproductively sterile. In present study, there was a comparison of testicular epididymal morphology serum hormone concentrations among silver foxes, hybrids during pre-breeding period, using 20 male 15 HSBs (silver male × blue female hybrids) HBSs (blue male × silver hybrids), respectively. Hybrids had smaller diameter seminiferous tubules than pure-species males, testes did not differ in mean size relative weight from males. There were many Sertoli cells spermatogenic foxes while numbers spermatogonia primary spermatocytes less with no secondary hybrids. Furthermore, testosterone estradiol less, FSH, LH, PRL greater that (P
