Pollen extract for chronic prostatitis-chronic pelvic pain syndrome.

Prostatitis syndrome is a frequent condition in men. It is not known in most patients if the prostate is the only organ involved. Therefore, the disease is characterized as chronic prostatitis-chronic pelvic pain syndrome (CP-CPPS). Although many studies have been performed in patients with CP-CPPS, current trial evidence is conflicting and therapeutic options are controversial. Given the need for long-term treatment in CP-CPPS patients, phytotherapeutics, such as pollen extract, are an option due to few side effects. Preclinical studies on pollen extract have shown effects on smooth muscles of the bladder and urethra, strong antiinflammatory effects, and antiproliferative effects.
