During this exam for sexually transmitted infections, the doctor:

• Looks for discharge from your 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.
• Gently examines the penis and looks for any abnormalities, such as open sores, warts, or scar tissue. If you’re having issues with a tight foreskin, the doctor will examine the foreskin.
• Checks your testicles for swelling and tenderness.
• May look at the end of your large intestine (rectum) for discharge. The doctor may also check your prostate for swelling and tenderness.
• May use a small scope to look at the walls of your rectum for discharge and inflammation.
• May take a urine sample to test for gonorrhea and chlamydia.
