Examination of expressed prostatic secretions tests a sample of the
secretion for signs of inflammation or bacterial infection.
While you bend over or lie on your side or back, the doctor inserts
a lubricated, gloved finger into the rectum and presses each side of the

The prevalence of obesity among American men has doubled in only 25 years,
and it’s killing us. A 2004 survey published in the Journal of the American
Medical Association found that 71% of men 20 years old and over were
overweight and 31% were obese. The same survey conducted in the late 1970s had

Science is searching for the causes of obesity and exploring the role of
genes, the diets of pregnant women, and the feeding habits of babies....

The results of the test may help show which type of prostatitis
is causing your symptoms. But this test often fails to provide conclusive
evidence of the cause of symptoms.
