Doctor's answer:
Hello: Your condition is uncertain, and it is very likely to be related to your own psychological factors! Many men cannot determine whether they have erectile dysfunction, but they can judge the nature of erectile dysfunction from the nocturnal penile erection. Normal men of all ages can experience reflexive penile erection during sleep. During adolescence, the average number of nightly erections is about 6, with each lasting 20-30 minutes; young and middle-aged adults have about 4 nightly erections on average; healthy elderly people over 65 still have a total of 1-1.5 hours of nocturnal erection time per night. Even children often have penile erections during sleep.Clearly, nocturnal reflexive penile erection is unrelated to sexual stimulation and is not affected by psychological factors. Therefore, it can be used to distinguish whether erectile dysfunction is caused by psychological factors or by medical factors. If an erectile dysfunction patient has no nocturnal erections or the degree of erection is below the normal value for their age group, it may indicate a medical factor, requiring further investigation to identify the root cause. If an erectile dysfunction patient has normal nocturnal erections, it is unlikely to be caused by medical factors but rather by psychological and mental factors. Here are several methods for self-assessing nocturnal penile erection:
(1) Stamp Test: Use four stamps to surround 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 penile erection. If the overlapping part has come loose, it is not meaningful.
(2) Penile Circumference Measurement: There is a commercially available tape measure (usually paper-based) with one end connected to a square buckle. Before going to sleep, wrap it around the penis, and one end...
