ELI5: Having to turn your head and cough during a physical?

What is the doctor actually looking for in your Testicles when he asks you to turn your head and cough?

The doctor is checking for a hernia (usually an inguinal hernia) which is when a part of your belly pokes through where it shouldn't.

Coughing can make it more noticeable. Turning your head prevents you from coughing on the doctor.
