Hormonal regulation of activities of 4-ene-5 beta- and 5 alpha-reductases and 17 beta-hydroxy-dehydrogenase in immature golden hamster testis.


We have reported [1-3] in immature golden hamster testis that 5 beta-reductase is localized in the tubular nongerm cells, while 5 alpha-reductase is present in the interstitial tissue and that the 17 beta-hydroxy-dehydrogenase activity is found predominantly in the tubular nongerm cells. Hormonal regulation of these enzyme activities was examined in the… (More)
