    Endocri Study

    Was doing some research on inhibitors and I came across this study. Good news for the people who take arimidex , as always, but bad news for people who want to keep DHT levels down using propecia. This is just an abstract.



    Effect of dual inhibition of 5-alpha-reductase and aromatase on spontaneously developed canine prostatic hypertrophy.

    BACKGROUND: Our aim was to assess the effect of dual inhibition of 5-alpha-reductase and aromatase on prostate glands. METHODS: We investigated the morphological changes in the prostate gland and the changes in the hormonal environment after administration of finasteride and arimidex to intact canine specimens. The study consisted of four groups: a 5-alpha-reductase only group (5RI only, n = 5); a 5RI plus aromatase-inhibitor combination group (5RI + ARI combination, n = 5); a BPH control group (n = 3); and a castration control group (n = 3). Finasteride (1 mg/kg/day) and the same dose of arimidex were orally administered for 80 days. RESULTS: In the 5RI group, a significant decrease in the serum dihydrotestosterone (DHT) level was found, and prostatic volume was significantly decreased. However, significant increases in serum testosterone (T) and DHT levels were observed, with a concomitant increase in prostatic volume in the 5RI + ARI combination group. Morphometric analysis showed that histopathological findings in the 5RI + ARI combination group were similar to those in the BPH control group. CONCLUSIONS: Dual inhibition of 5-alpha-reductase and aromatase resulted in a significant increase in prostate volume, accompanied by a 3-10-fold increase in serum testosterone levels and a significant increase in testicular volume.

    I know the dosage is way more than we would use. Has anyone used arimidex and propecia together and had their DHT levels checked? This study has gotten me really curious.
