It produces a fluid that helps transport sperm during ejaculation. Inflammation or infection of the prostate results in prostatitis. It affects about 10% of men of all ages but most often those in their 40s. Prostatitis has several forms. The most common is a nonbacterial (no infection) inflammation that causes pelvic pain and is also called chronic pelvic pain syndrome. Less common is an acute bacterial infection lasting for several days, and least common is a chronic bacterial infection that recurs and may last for weeks or months.</span> 307 5 527 527 10.1001/jama.2011.2008 http://pubs.jamanetwork.com/article.aspx?articleID=1104938
