What causes blood in semen in men?

Blood in semen in men is generally caused by overly intense sexual activity, seminal vesiculitis, prostatitis, urethritis, or epididymitis. Patients should promptly visit a正规 hospital to identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Overly intense sexual activity: Excessively vigorous sexual activity may cause injury to the reproductive organs, leading to blood in semen. This is usually due to excessive force or improper positions. In such cases, it is recommended to temporarily abstain from sexual activity to allow the body sufficient time to recover. Additionally, attention should be paid to the manner and frequency of sexual activity to prevent re-injury.

2. Seminal vesiculitis: Seminal vesiculitis is usually caused by infections of the urinary and reproductive systems, and may also result from intestinal inflammation. When the seminal vesicles become infected, they may become congested and swollen; in severe cases, capillaries may rupture, causing blood in semen. Patients often experience additional symptoms such as difficulty urinating, frequent urination, and urgency. In such cases, patients may take medications such as levofloxacin tablets, minocycline hydrochloride tablets, or cefaclor capsules under medical guidance.

3. Prostatitis: When the prostate gland becomes infected by pathogens or stimulated by certain non-infectious factors, it may become congested and swollen. Severe cases may lead to capillary rupture and thus cause blood in semen. Patients are advised to take medications such as Sanjin tablets, Qianlieshu capsules, or terazosin hydrochloride tablets under a doctor's supervision.

4. Urethritis: In severe cases, urethritis may spread upward and infect the seminal vesicles, causing seminal vesiculitis and resulting in blood in semen. Symptoms of urethritis include redness, swelling, itching, pain at the urethral opening, and purulent discharge. If the condition progresses, it may also cause penile swelling, frequent urination, urgency, and painful urination. Patients may take medications such as ampicillin capsules, compound Shewei capsules, or cefuroxime axetil capsules under medical guidance.

5. Epididymitis: Epididymitis refers to infection of the epididymis, which may be caused by bacterial, viral, or chlamydial infections. Inflammatory stimulation may lead to congestion and edema of the local mucosa of the epididymis. If not treated promptly, the local mucosa may become damaged, resulting in blood in semen. Patients may follow medical advice to use medications such as minocycline hydrochloride tablets, cefaclor capsules, or acetaminophen tablets to alleviate symptoms.

If blood in semen occurs, prompt medical consultation is recommended so that doctors can make an accurate diagnosis and provide appropriate treatment based on individual circumstances. Additionally, maintaining healthy lifestyle and hygiene habits, avoiding excessive sexual activity and improper positions, can help prevent the occurrence of blood in semen.
