Hematospermia: Causes and Concerns for Men - Urology

Share to:

Ejaculation occurs as a result of a complex interplay of physiological and neurological processes. During sexual arousal, signals from the brain stimulate the reproductive system, leading to the production of sperm in the testes and seminal fluid in the seminal vesicles and prostate


Hello! Doctor, I would like to ask you about something.
On September 30th, at 6 AM, I performed a DIY and the semen I ejaculated was normal.
However, around 3 PM, after having intercourse with my girlfriend, I masturbated for a while and ended up ejaculating blood.
Can you explain why this happened?

Hello: There are many conditions that can lead to hematospermia.
The following diseases may cause this condition, but please note that in many cases, the cause remains unknown.
[1] Trauma - such as urethral injury.
[2] Inflammatory responses - such as urethritis, prostatitis, seminal vesiculitis, and urinary tuberculosis.
[3] Tumors - such as benign prostatic hyperplasia, prostate cancer, and seminal vesicle tumors.
[4] Congenital factors - such as ectopic ureter, where the ureter opens into the urethra, which can easily lead to hematospermia.
[5] Vascular factors - such as mucosal hyperplasia of the seminal vesicles, or abnormalities and engorgement of the posterior urethral blood vessels.
[6] Other factors - such as cirrhosis, schistosomiasis, and leukemia.

Hematospermia, or the presence of blood in semen, can be a concerning symptom for men. It is important to understand that while it can be alarming, it is not always indicative of a serious underlying condition. There are various potential causes of hematospermia, and understanding these can help alleviate concerns and guide appropriate action.

Causes of Hematospermia:
1. Infections: One of the most common causes of hematospermia is an infection in the reproductive system. This can include prostatitis (inflammation of the prostate), epididymitis (inflammation of the epididymis), or urethritis (inflammation of the urethra). These infections can lead to inflammation and bleeding, resulting in blood being present in the semen.

2. Trauma: Physical trauma to the genital area can also cause hematospermia. This could be due to vigorous sexual activity, injury during sports, or even medical procedures such as biopsies or surgeries involving the prostate or other reproductive organs.

3. Vascular Issues: Abnormalities in blood vessels, such as varicoceles (enlarged veins in the scrotum) or other vascular malformations, can lead to bleeding during ejaculation.

4. Prostate Issues: Conditions affecting the prostate, such as benign prostatic hyperplasia (BPH), prostate cancer, or prostate biopsies, can also result in blood in the semen.

5. Systemic Conditions: Certain systemic conditions, such as hypertension or blood clotting disorders, can contribute to hematospermia.
6. Tumors: Although less common, tumors in the reproductive system can cause bleeding, leading to hematospermia.

When to Seek Medical Attention:
If you experience hematospermia, especially if it is accompanied by other symptoms such as pain, swelling, fever, or if it persists over time, it is advisable to seek medical evaluation. A healthcare provider may perform a physical examination, take a detailed medical history, and order tests such as blood tests, urinalysis, or imaging studies to determine the underlying cause.

Your Situation:
In your case, you mentioned that you experienced normal semen in the morning but noticed blood in the semen after sexual activity in the afternoon. This could potentially be related to several factors, including the intensity or duration of the sexual activity, which may have caused minor trauma or irritation. It is also possible that an underlying infection or inflammation could be exacerbated by sexual activity.

Recommendations:
1. Monitor Symptoms: Keep track of any additional symptoms you may experience, such as pain during ejaculation, changes in urination, or any other unusual signs.

2. Hydration and Rest: Ensure you are well-hydrated and allow your body to rest. Sometimes, minor issues can resolve on their own.

3. Consult a Healthcare Provider: If the hematospermia persists or if you have any concerns, it is best to consult a healthcare provider. They can provide a thorough evaluation and appropriate management based on your specific situation.

In conclusion, while hematospermia can be concerning, it is often not a sign of a serious condition. Understanding the potential causes and knowing when to seek medical attention can help manage any anxiety associated with this symptom. Always prioritize your health and well-being by consulting with a healthcare professional for personalized advice and treatment.
