Hormone Doesn’t Shrink Prostate

A hormone treatment used in a small study did not slow aging-related prostate growth, researchers said. The study included 114 men, age 50 or older. They were asked to apply a gel to the skin of their trunk or upper leg each day for 2 years. They were randomly assigned into two groups. One group received a gel that contained the hormone dihydrotestosterone. The gel for the other group contained no hormone. At the beginning and end of the study, the men had ultrasound tests to show prostate size. In both groups, the size increased over time. There was no difference between the groups. The journal Annals of Internal Medicine published the study November 15.
