<s>[INST] Hello doctor, What will my doctor exactly do while examination, when I tell him I am having erection problems? [/INST] Hi. It depends on what all positive findings you give while giving history. For example, the doctor will ask you for diabetes, high blood pressure, any regular medicine intake, psychiatric medicines, low hemoglobin symptoms, etc. These diseases usually cause ED (erection dysfunction) as a secondary cause. Then depending on what comes out of the conversation, the check-up will consist of general body workup. For the ED part, the doctor will surely look for a local problem, the size, and consistency of testis, the shape and size of the penis. He will then try to check for erection as a reflex on touching and will also check for skin retraction. The next step can be a stamp test or a penile Doppler, where the blood supply of the organ will be checked. There can also be a nerve conduction test done if the doctor thinks that the nerve supply is deficient. I hope this helps. </s>
