Repeated administration of human chorionic gonadotropin to rats results in a maximal depression of testicular microsomal heme and cytochromeP-450 levels at 24 h, followed by increases that plateau at pretreatment levels by day six. Associated with the depressed levels of microsomal heme and cytochromeP-450 is an increase of testicular microsomal heme oxygenase activity at 12–24 h. Testicular mitochondrial δ-aminolevulinic acid synthase activity was increased at 24 h, and remained elevated throughout the 9-day treatment period. Pretreatment with 1,4,6-androstatrien-3,17-dione, an aromatase inhibitor, failed to prevent the depression of testicular microsomal heme or cytochromeP-450 or increased heme oxygenase activity caused by repeated administration of human chorionic gonadotropin, and administration of estradiol benzoate failed to alter testicular microsomal heme oxygenase activity suggesting that these parameters were not related to altered testicular estrogen content caused by increased aromatase activity. These results suggest that increased testicular heme oxygenase activity is associated with decreased microsomal heme and cytochromeP-450 content during human chorionic gonadotropin-induced desensitization.
