Regular physical examinations of your genitals, anus (asshole), and rectum (the inside of your ass) can help diagnose infections. Early diagnosis of a problem usually means it can be treated with fewer drugs or minor surgery.
External visual examination: Your doctor examines the outside of your penis and scrotum (balls) for lesions (such as herpes), genital warts, or any other evidence of infection.
Internal rectal examination: Your doctor will insert one gloved finger into your rectum to feel your prostate gland. Swelling of this gland can indicate cancer. Infections that usually appear on your penis or scrotum can “travel” to your anus or rectum, especially genital warts and herpes lesions. The doctor may also do a rectal Pap smear .
