Today, with the highly developed medical level, the methods of diagnosing diseases are different. But using stamps to diagnose impotence, I believe many male friends have never heard of it. So today, Xiaobian will take you to understand this strange diagnostic method - "stamp test" method.
The oldest method to detect whether a male penis has natural congestion and erection at night is the "stamp test". Wrap two conjoined stamps around the penis and glue them together. If the stamps are rolled up, cracked and torn off when you wake up, it will prove that the penis has had an erection when sleeping at night. However, this diagnostic method also has disadvantages, that is, it is only a "qualitative" test, and cannot record the number of erections and specific blood flow.
Since Knoll, the American professor of andrology, invented the "bioelectricity measurement system", the measurement of the number of times, duration, length, thickness and blood volume changes of the penis of male patients in the night has become well founded. These parameters can also be printed out with waveforms, and doctors can judge the vascular cause of erectile dysfunction like reading ECG paper. The patient will not feel pain, just put several electrodes on the penis before going to bed.
