Blood in Urine: A Teen's Guide to Urological Health - Urology

Share to:

Hello, Dr. Lin?


Hello Doctor, I am Xiao D.
Thank you for your reply.
I am 16 years old and have been masturbating frequently.
A few days after my last incident, I masturbated again, and I was relieved to find no blood when I wiped after ejaculation.
However, after dinner, I noticed blood in my underwear when I urinated, and my penis feels sore.
The amount of blood is about the size of a pinky finger.
Is this considered hematospermia? What could be the implications, and will it resolve on its own? Thank you.

Dr. Lin Hexing reply Urology


Hello, Xiao D: The diagnosis of hematospermia is not definitively established by finding blood in your underwear after urination or experiencing a burning sensation in the penis.
A semen analysis is required for a proper diagnosis.
I advise you not to engage in excessive masturbation at a young age.

Hello, D. Thank you for reaching out with your concerns. It's understandable to feel worried when you notice blood in your urine, especially at your age. Let's break down your situation and provide some clarity on what might be happening.

First, it's important to distinguish between blood in urine (hematuria) and blood in semen (hematospermia). Based on your description, it sounds like you noticed blood in your underwear after urination, which suggests hematuria. Hematuria can occur for various reasons, and while it can be alarming, it is not always indicative of a serious condition.

Given your age and the fact that you mentioned frequent masturbation, it's possible that the blood could be related to a minor injury or irritation in the urinary tract or genital area. Activities such as vigorous masturbation can sometimes lead to small tears or irritation, which might cause blood to appear. However, it's essential to consider other potential causes as well.

Some common causes of hematuria in teenagers include:
1. Urinary Tract Infections (UTIs): These can cause irritation and inflammation in the urinary tract, leading to blood in the urine. Symptoms may include a burning sensation during urination, frequent urination, and lower abdominal pain.

2. Kidney Stones: Although less common in teenagers, kidney stones can cause bleeding and pain. If you experience severe pain in your back or side, this could be a possibility.

3. Trauma or Injury: Any recent injury to the pelvic area or vigorous physical activity could lead to bleeding.

4. Infections or Inflammation: Conditions such as prostatitis (inflammation of the prostate) or urethritis (inflammation of the urethra) can also cause blood in the urine.

5. Other Medical Conditions: While less common, certain medical conditions can lead to hematuria, so it's essential to rule these out.

Since you mentioned that the blood was about the size of a small pinky and that you felt a sensation of soreness, it's advisable to consult a healthcare professional. They can perform a thorough evaluation, including a physical examination and possibly urine tests, to determine the underlying cause of the bleeding.
In terms of whether this will resolve on its own, it depends on the underlying cause. If it is due to a minor injury or irritation, it may resolve with time and rest. However, if it is due to an infection or another medical condition, appropriate treatment will be necessary.

It's also important to monitor your symptoms. If you experience any of the following, seek medical attention promptly:
- Increased frequency or urgency of urination
- Pain or burning sensation during urination
- Fever or chills
- Severe abdominal or back pain
- Any additional bleeding or unusual symptoms
In conclusion, while it’s possible that the blood in your urine is due to a minor issue, it’s crucial to get it checked out by a healthcare provider to ensure there are no serious underlying conditions. They can provide you with the appropriate care and guidance. Remember, taking care of your urological health is important, and seeking help is a positive step.
