Abstract

Benign prostatic hyperplasia (BPH) has a high incidence in both dogs and men. However, hormone physiology involved in the pathogenesis of BPH remains with many gaps to be elucidated. Moreover, conservative therapy with the use of finasteride for the treatment of BPH, both in men and dogs, is not yet fully established because of the possible side effects, causing controversy in their use of reproductive clinical scale. However, it is known that the use of Finasteride promotes reduction in prostate volume, and thus, the symptoms of the affected individual. Such effects occur by decrease the levels of dihydrotestosterone and consequently the activation of the apoptotic cascade, which is a form of cell death in the body, and very important for homeostasis of various systems. Hence, the objective of this work is to promote the characterization of changes resulting from benign prostatic hyperplasia in dogs undergoing treatment with finasteride , using features such as the immunohistochemistry to evaluate the expression of apoptosis factors ( Caspase3 ) and evaluate the hormone levels, measuring the main hormones involved (testosterone and dihydrotestosterone) .So, this work will contribute to further clarifications about the changes that occur with treatment of choice for benign prostatic hyperplasia in men and dogs.
