What happens when a boy's underwear is wet when he wakes up?

Boys' wet underwear in the morning may be caused by factors such as physiological nocturnal emissions, secretion of bulbourethral gland fluid, night sweats, urinary system infection or diabetes.

1. Physiological nocturnal emissions:

Men from puberty to adulthood may experience unintentional ejaculation during sleep, which is called nocturnal emissions. This is a manifestation of the normal spermatogenic function of the testicles. After the semen accumulates to a certain amount, it is discharged through nocturnal emissions. 1-2 times a month is normal, accompanied by pleasure but no pain, and the semen is milky white and semi-fluid.

2. Secretion of bulbourethral gland fluid:

The bulbourethral glands secrete transparent mucus during sexual excitement. In the morning, stimulation of bladder filling or sexual dreams may lead to increased secretion. This liquid is small in volume, colorless and odorless, and is a normal physiological reaction. It has a similar composition to prostatic fluid but is thinner.

3. Sweating at night:

Sleeping in an overheated environment or with a high metabolism can cause perineal sweating. Sweat may be mistaken for abnormal secretions, but is actually a colorless and odorless transparent liquid. This can be improved by adjusting the room temperature to 22-26°C and choosing pure cotton breathable underwear.

4. Urinary system infection:

Urethritis or prostatitis may cause purulent discharge from the urethral opening in the morning. This type of liquid is mostly yellow-green with an odor and a burning sensation when urinating, which may be related to gonococcal and chlamydial infections. Urine routine and prostatic fluid examination are required for diagnosis.

3. Diabetes related:

Poor blood sugar control may cause elevated urine sugar and autonomic neuropathy, resulting in nocturnal urinary leakage or increased secretions. The typical symptom is sweet-smelling mucus in underwear, which may be accompanied by symptoms of polydipsia and polyuria. Fasting blood sugar and glycated hemoglobin need to be tested.

It is recommended to keep the vulva clean and dry, change cotton underwear every day and wash the perineum with warm water. Avoid wearing tight pants that compress your genitals and reduce your intake of spicy food. Observe the changes in secretion properties. If symptoms such as abnormal color, odor, or painful urination persist, you should go to the urology department for examination in time. Limit the amount of water you drink at night to less than 200ml, and empty your bladder before going to bed. Moderate exercise can help improve your metabolism, but you need to avoid excessive fatigue. Parents of teenagers should correctly understand the phenomenon of nocturnal emissions to avoid causing psychological pressure on their children.
