Hemospermia: Causes of Blood in Semen and When to Worry

Hemospermia, the presence of blood in semen, can be concerning. While alarming, it is frequently a benign condition that resolves without specific intervention, especially in men under 40 years of age. It often appears spontaneously and may disappear within a few weeks, indicating a self-limiting nature.

Common Causes of Hemospermia

Infection and inflammation within the genitourinary tract are common causes of hemospermia, particularly in younger men. Conditions such as prostatitis (inflammation of the prostate gland), urethritis (inflammation of the urethra), and epididymitis (inflammation of the coiled tube behind the testicle) can lead to bleeding. These inflammatory processes can cause irritation, mucosal edema, and increased blood flow in the accessory sexual glands and their ducts, resulting in the appearance of blood in semen.

Medical procedures are another common trigger for hemospermia. A prostate biopsy, for example, frequently causes blood in the semen. This bleeding can persist for several weeks or even months. Other procedures like vasectomy or even vigorous sexual activity, including prolonged abstinence followed by ejaculation, can also lead to temporary hemospermia.

Obstructions in the male reproductive system’s tubes may also contribute to hemospermia. Blockages, such as those in the ejaculatory ducts, can lead to a buildup of pressure. This increased pressure can cause small blood vessels lining the ducts to rupture, releasing blood into the semen. Such obstructions can be congenital or acquired from inflammation or scar tissue.

In some instances, hemospermia may signal the presence of tumors or other systemic conditions. Malignancies of the prostate, seminal vesicles, or testes are uncommon causes, more frequently observed in men over 40 years old. Systemic issues like high blood pressure or certain bleeding disorders can also result in hemospermia due to their effects on blood vessels and clotting.

When to Consult a Doctor

The decision to seek medical attention for hemospermia often depends on several factors, with age being a primary consideration. For men under 40 years old who experience isolated hemospermia without other symptoms, the condition frequently resolves on its own and may not require extensive evaluation beyond basic tests for infection. Many cases in this age group are linked to benign causes like infection or minor trauma.

However, a medical consultation is recommended for men over 40 years of age, even if hemospermia is the sole symptom. This is due to a slightly increased, though still low, risk of underlying serious conditions like prostate cancer in this age group. Persistent or recurrent episodes of blood in semen, regardless of age, also warrant a doctor’s visit.

Certain associated symptoms should always prompt a medical evaluation. These include pain during urination or ejaculation, fever, unexplained weight loss, or visible blood in the urine (hematuria). A family history of prostate cancer or a history of bleeding disorders are additional factors that warrant professional assessment.

Diagnosis and Treatment Approaches

A healthcare provider will begin by taking a detailed medical history, asking about symptom duration and any recent procedures or injuries. A physical examination follows, which often includes checking blood pressure, examining the external genitalia, and performing a digital rectal examination (DRE) to assess the prostate gland.

Further diagnostic steps may involve laboratory tests. A urinalysis and urine culture can detect urinary tract infections, while testing for sexually transmitted infections (STIs) may be performed, especially in younger individuals. For men over 40, a prostate-specific antigen (PSA) blood test is recommended to screen for prostate cancer. Imaging studies, such as transrectal ultrasonography (TRUS) of the prostate and seminal vesicles, can help identify structural abnormalities like cysts, stones, or tumors. Magnetic resonance imaging (MRI) may be used for more detailed visualization of pelvic structures if TRUS findings are inconclusive.

Treatment for hemospermia is tailored to the identified underlying cause. If an infection is diagnosed, a course of antibiotics is prescribed. For inflammation, anti-inflammatory medications may be used. When no specific cause is found, particularly in younger men with isolated, short-lived episodes, a “watchful waiting” approach with reassurance is common, as the condition often resolves spontaneously. If a more serious issue, such as a tumor or significant obstruction, is identified, specific treatments, including surgical intervention or other specialized therapies, are recommended.
