What's the reason why boys' underwear suddenly gets wet?

A sudden wet spot in boys' underwear may be caused by factors such as physiological ejaculation, secretion of bulbourethral gland fluid, urinary incontinence, reproductive system infection, or diabetes. It needs to be judged based on specific symptoms.

1. Physiological ejaculation:

Men in puberty or in the sexually active stage may experience nocturnal nocturnal emissions or prostatic fluid leakage during sexual excitement, causing local moisture in their underwear. This type of condition is usually odorless, accompanied by sexual fantasies or morning erections, and is a normal physiological reaction. Maintaining a regular sex life or moderate masturbation can reduce fluid accumulation. Just choose breathable cotton underwear every day.

2. Secretion of bulbourethral gland fluid:

Before sexual stimulation or urination, the bulbourethral glands secrete clear mucus to lubricate the urethra. Excessive secretion may penetrate underwear, and the liquid will be clear and odorless, often occurring during sexual excitement. This is related to the excitement period in the male sexual response cycle and does not require special treatment, but attention should be paid to distinguishing it from pathological secretions.

3. Stress urinary incontinence:

A small amount of urine leakage may occur when abdominal pressure increases, which is common in patients after prostate surgery, obesity or pelvic floor muscle relaxation. Urine is light yellow and smells of ammonia, which often occurs when coughing, sneezing and other actions. It is recommended to perform Kegel exercises to enhance pelvic floor muscle control. In severe cases, urodynamic examination is required to rule out neurogenic bladder.

4. Reproductive system infection:

Urethritis or prostatitis can cause abnormal discharge, and gonococcal or chlamydial infections are common. The secretions are mostly yellow-green with a peculiar smell, and may be accompanied by painful urination and lower abdominal distension. Routine urine and pathogen testing are required, and antibiotics such as levofloxacin and doxycycline are commonly used in clinical treatment. Sexual life is prohibited during this period.

5. Diabetic complications:

Long-term high blood sugar may damage the nerves in the bladder, causing overflow incontinence. The amount of urine is large and frequent, and may be accompanied by symptoms such as thirst and polydipsia. Blood sugar levels need to be monitored, blood sugar controlled with insulin or metformin, and bladder function training performed.

It is recommended to observe the liquid properties and frequency of occurrence. If the secretions are discolored, smelly, or accompanied by itching and pain, you should seek immediate medical attention from a urology department. Pay attention to the cleanliness of the perineum every day and avoid wearing underwear made of chemical fiber. Diabetic patients need to monitor their blood sugar regularly, and prostatitis patients can relieve symptoms by taking a sitz bath in warm water. Maintaining moderate exercise can help improve pelvic floor muscle function and reduce the occurrence of stress urinary incontinence. People with frequent nocturnal nocturnal emissions can empty their bladder before going to bed and sleep on their side to reduce stimulation.
