How to treat impotence

Doctor's answer:

Hello; Many men cannot determine whether they have erectile dysfunction, but in fact, they can judge the nature of erectile dysfunction based on the nocturnal penile erection. Normal men of all ages can experience reflexive penile erections during sleep. During puberty, the average number of nightly erections is about 6, each lasting 20-30 minutes; young and middle-aged adults have an average of about 4 nightly erections; healthy elderly people over 65 still have a total of 1-1.5 hours of nocturnal erection time per night. Even children often experience penile erections during sleep.
Clearly, nocturnal reflexive penile erections are unrelated to sexual stimulation and are not influenced by psychological factors. Therefore, they can be used to differentiate whether erectile dysfunction is caused by psychological factors or by medical conditions. If an erectile dysfunction patient has no nocturnal erections or if the degree of erection is below the normal range for their age group, it may indicate a medical condition, requiring further investigation to identify the root cause. If an erectile dysfunction patient has normal nocturnal erections, it is unlikely to be caused by a medical condition but rather by psychological factors.
There are several methods for self-assessing nocturnal penile erections:
(1) Stamp Test: Place four around the penis, stick the overlapping parts together to form a ring, and then go to sleep. In the morning, check if the stamp has torn. If it has, it indicates nocturnal erections. If the overlapping part comes loose, it is not meaningful.
(2) Penile Circumference Measurement: Use a commercially available tape measure (usually paper-based) with one end attached to a square buckle. Before going to bed, wrap the tape around the penis, and let one end extend through the buckle. First, record the baseline circumference of the penis in its flaccid state. The next morning...
