Urinary Discharge: Is It Normal or a Sign of Infection? - Urology

Is this a secretion?


I would like to ask the doctor why, in the past few days, after experiencing an erection, even without the urge to ejaculate, I notice that my urine contains some milky-gray discharge after the first urination.
Sometimes, after urinating, I feel a warmth at the tip of the urethra, or it feels like I still have a little urge to urinate.
Is this semen, or could it be discharge due to inflammation? Is it possible to have prostate inflammation or issues at the age of 20?

Y, 20~29 year old female. Ask Date: 2014/01/16

Dr. Lin Hexing reply Urology


Hello: It is recommended to visit the urology outpatient clinic for examination.
Wishing you good health.

When it comes to urinary discharge, especially in the context of recent sexual activity or physiological responses such as erections, it is important to differentiate between normal bodily functions and potential signs of infection or inflammation. The presence of a grayish discharge in your urine, particularly after an erection, can be concerning and warrants further investigation.

Firstly, it is essential to understand that the male urinary tract and reproductive system are interconnected. The prostate gland, seminal vesicles, and urethra all play roles in the production and transport of semen and urine. The grayish discharge you are observing could potentially be a mixture of urine and prostatic fluid, which is not uncommon. However, if this discharge is accompanied by a sensation of heat or discomfort at the urethral opening, it may indicate inflammation or infection.

Infections of the urinary tract, including urethritis (inflammation of the urethra), can occur due to various pathogens, including sexually transmitted infections (STIs) such as Chlamydia or Gonorrhea. Symptoms of urethritis can include discharge, burning during urination, and a feeling of urgency or incomplete voiding. Given your description, it is possible that you could be experiencing a mild infection or inflammation of the prostate (prostatitis), which can occur even in younger men in their 20s.

Prostatitis can present with a variety of symptoms, including pelvic pain, discomfort during urination, and changes in urinary habits. It can be caused by bacterial infections or may be non-bacterial in nature, often linked to pelvic floor dysfunction or other factors. While it is less common for younger men to experience prostatitis, it is certainly possible, especially if there are risk factors such as recent sexual activity or a history of STIs.

To address your concerns, here are some recommendations:
1. Seek Medical Evaluation: It is crucial to consult a healthcare provider, preferably a urologist, who can perform a thorough examination and possibly conduct tests such as urinalysis, urine culture, and STI screening. This will help determine if there is an underlying infection or other issues that need to be addressed.

2. Hydration: Ensure you are drinking plenty of fluids, as this can help flush out the urinary tract and may alleviate some symptoms.

3. Avoid Irritants: Reduce or eliminate the intake of alcohol, caffeine, and spicy foods, as these can irritate the bladder and exacerbate symptoms.

4. Monitor Symptoms: Keep track of any additional symptoms that may arise, such as fever, chills, or worsening pain, and report these to your healthcare provider.

5. Safe Sexual Practices: If you are sexually active, consider using protection to reduce the risk of STIs, and communicate openly with partners about sexual health.

In summary, while the presence of a grayish discharge after an erection may not be inherently alarming, the accompanying symptoms you describe suggest that it would be prudent to seek medical advice. Early intervention can help prevent complications and ensure that any potential infections are treated promptly.
