Maybe you were nearby in a waiting area.
Maybe you were in an adjacent room - an adjacent exam room, an adjacent bathroom or doctor's office
You heard it
The unmistakable cough of a male patient being checked for hernia.
Perhaps you saw the patient go into the room just before, so you know what he looks like.
You heard the cough. & you immediately knew what was taking place.
How did that, or how would that, affect you? Did it make you feel anxious? Did you conjure up a mental image of what was happening? Did you get aroused? You happened to listen in on a man undergoing a personal, private, perhaps awkward, moment. You didn't have to see it happening. After hearing the cough, you may as well have seen it, as you have a vivid idea of what was going on behind closed doors
And what did it do to you?
