Patient's question:
Why does the penis always shrink during the day and then get erect after urinating? What's going on? Could it be erectile dysfunction?Doctor's answer:
Every night, I get up once to use the restroom. That's just a symptom of a normal physiological urination reflex!! The main issue is the foreign body sensation in the urethra! Also, the patient wakes up during light sleep. In light sleep, any movement will wake them up, but they quickly fall back asleep! If there's a foreign body in the urethra during this time, it will cause the urge to urinate, making the patient get up to use the restroom.This condition is more common in elderly people, those who frequently engage in sexual activity, and individuals with prostate lesions! Prostate lesions can lead to the leakage of prostatic fluid, causing a foreign body sensation. Prostate lesions can also disrupt the vegetative nervous system of the prostate! Moreover, these patients often exhibit symptoms of neurosis! Their light sleep is poor, and they are easily startled.
