‘After I urinate, some clear, bad-smelling liquid comes out. Is this a disease or normal? I’m 15’

1. Is it normal for a teenage boy to notice clear, foul-smelling discharge or fluid after urination, or can it indicate an infection or other condition?

The urologist explains that a clear or slightly whitish discharge in teenage boys can occasionally occur due to normal physiological reasons, such as residual semen or pre-ejaculate fluid. “However, when the discharge is accompanied by a foul smell, burning sensation, itching, or pain during urination, it could indicate an underlying infection or inflammation in the urinary or reproductive tract.” Dr Prakash states that it is important not to ignore such symptoms, especially if they persist or recur.

2. What are the possible causes of clear, foul-smelling discharge after urination — could it be a urinary tract infection, poor hygiene, or something else?

Foul-smelling discharge after urination can be linked to several causes. “The most common are urinary tract infections, poor genital hygiene, or inflammation of the urethra known as urethritis,” Dr Prakash notes. However, in some cases, it may result from sexually transmitted infections such as gonorrhea or chlamydia, especially in sexually active teenagers. The urologist further points out that dehydration and poor fluid intake can also lead to concentrated urine with an unpleasant odour: “though this usually does not cause discharge”.  Identifying the exact cause, thus, requires medical evaluation.

3. At what point should someone seek medical attention for such symptoms, and what tests or check-ups are usually recommended?

Dr Prakash advises that one should seek medical attention if the discharge is persistent, foul-smelling, or associated with pain, itching, swelling, fever, or blood in the urine. “A urologist will typically recommend a urine routine and culture test, urethral swab analysis, and sometimes an ultrasound of the urinary tract to identify infections or anatomical abnormalities. Early consultation helps prevent complications and ensures proper treatment.”

In sexually active teenagers, foul smelling discharge may also result from sexually transmitted infections such as gonorrhea or chlamydia

4. Can hormonal changes during puberty cause discharge in teenage boys, and how can one differentiate between normal secretions and signs of disease?

Dr Prakash affirms that hormonal changes during puberty can stimulate the glands around the penis to secrete small amounts of clear or milky fluid, which is usually normal. However, he points out that such secretions are typically odourless, occur occasionally, and are not associated with pain or burning. “In contrast, discharge due to infection is often cloudy or thick, has a foul odour, and may cause discomfort.” He recommends that if a teenager is unsure or experiences new or worsening symptoms, it’s always safer to consult a doctor.

5. What preventive steps or hygiene practices can teenagers follow to maintain good urinary and reproductive health?

As per the urologist, maintaining proper genital hygiene is essential. “Teenagers should wash the genital area daily with mild soap and water, wear clean and breathable cotton underwear, and stay hydrated by drinking plenty of water. Avoiding the use of harsh soaps or deodorants in the genital region can prevent irritation.” For those who are sexually active, Dr Prakash recommends using protection and getting regular check-ups as preventive measures. “A balanced diet and good hydration also support urinary health,” he concludes.
