benign prostatic hyperplasia
"I'm a 70 year-old guy who has had BPH for over 10 years.  Was taking Avodart, which worked OK, but had the sexual side effect of reducing the amount of semen I produced, which greatly impeded my sexual performance.  Switched to 5 mg daily of Cialis 5 months ago.  I was pleased to find that semen production returned to normal in about 2 months, which was the main reason for switching drugs.  But much to my surprise I found that it reduced BPH symptoms by about 90%.  It's turned out to be a miracle drug for me--no side affects that I'm aware of.  Enhanced erections is an extra benefit."
