benign prostatic hyperplasia
"I am 65 years old  and have been on Avodart for one year.  My PSA had increased at a rapid rate to 3.6.  Biopsy was benign.  Frequent urination was of course an issue.  My PSA dropped almost by 50% in the first 6 months.  My sex drive is non existent and if I can get a partial erection I am able to have a small ejaculation.   Cialis will sometimes work.  The most dramatic side affect has been that I now have an almost full head of hair.  Prior to the Avodart therapy I was pretty bald on top and thinning on the sides.  My barber has been amazed, as have I."
