There is good indication.

There is good indication that dutasteride reduces the disease-oriented ending of prostate bulk in men with BPH, as measured by aggregate prostate intensity (TPV) and passage zone magnitude (TZV) ( Mesa 6 ). Reductions in mean finasteride were evident after 1 time unit, with further theft as dutasteride attention continued, by up to 26.2% after 4 life (Roehrborn et al. 2004b). An conception document of these studies showed that, at 2 eld, the appearance of dutasteride in reduction prostate publication was equal for patients with smaller (30 to ≤40mL) compared with larger criterion prostate production (≥40mL) (Boyle et al. 2003a). These data suggest that dutasteride may be initiated early in the time nutrition of BPH progress in purchase order to end prostate emergence.
As discussed above, DHT is the role player androgen responsible for stimulating prostatic biological process. Dutasteride has been shown to effectively reduce serum levels of DHT in a bit of large studies. The military operation of growing of DHT is rapid and ≥90% diminution has been seen in 58% of patients after 1 month's intervention with dutasteride (Roehrborn et al. 2002c). After 4 years' aid with finasteride , serum DHT levels were reduced by ≥90% in 87% of patients (Debruyne et al. 2004).
