Difficulty in erection is generally referred to as erectile dysfunction, and the results can usually come out on the same day of the examination, but the specifics should be based on the local hospital. Erectile dysfunction tests include laboratory tests, such as routine blood tests, urine tests, liver function, blood sugar, blood lipids, sex hormones, blood biochemistry, thyroid function and other tests, and if the test is performed in the morning, the results can usually be produced in the afternoon. Other tests include penile erection monitoring, such as penile nocturnal erection test, penile hardness test with audio-visual stimulation, penile cavernous injection vascular drug test, penile color Doppler ultrasonography, penile cavernous angiography, and erectile dysfunction rating scale, etc., and the results are usually available on the same day. The return time of all the above test results is subject to the local hospital. People with erectile dysfunction should go to the hospital in time for examination and active treatment after identifying the cause of the disease.
