title: Management of benign prostatic hyperplasia with particular emphasis on aromatase inhibitors.
abstract: The pathogenesis of human benign prostatic hyperplasia (BPH) has not been fully elucidated. There is, however, evidence that estrogens--besides other factors--might play an important role for the growth of the prostate. Consequently, estrogen deprivation might be a new, useful principle for a conservative treatment of BPH. Atamestane, a new, highly selective steroidal aromatase inhibitor has been proven to be successful in antagonizing experimentally-induced estrogen-related stromal overgrowth of the prostate in dogs and monkeys. Double-blind placebo controlled studies are now underway in Europe and the U.S.A. It is anticipated that these studies will give us a definite answer of the clinical validity of this concept in BPH patients in the near future. However, it is very important to take into consideration that for an effective treatment of BPH, a reduction of both the glandular and stromal elements has to be achieved. In other words, both androgens and estrogens seem to be involved in the regulation of (over)growth of the prostate. Therefore, a combination of an androgen and estrogen deprivation might be a more promising approach than any single treatment.
