Topic Overview

During a male genital exam for sexually transmitted infections, the doctor:

• Looks for discharge from the penis. The doctor may put a thin swab into the urethra and take a sample of fluid and cells to test for infections such as chlamydia or gonorrhea.
• Checks the testicles for swelling and tenderness.
• May use a small scope to look at the walls of the rectum for discharge and inflammation.
• May look at the end of the large intestine (rectum) for discharge and look at the gland that produces part of the semen (prostate) for swelling and tenderness.
• May take a urine sample to test for gonorrhea and chlamydia.
