What every man should understand about hematospermia or blood in semen

By Dr. David Samadi 

A condition known as hematospermia, which is blood in semen, can be a distressing experience for men. While the sight of blood may evoke anxiety, it’s essential to recognize that hematospermia is typically benign. This comprehensive guide will delve deeper into hematospermia, exploring its causes, diagnostic procedures, treatment options, and the importance of seeking medical evaluation.

Understanding Hematospermia 

Hematospermia is relatively common, particularly in men under the age of 40. Despite its alarming nature, it often resolves spontaneously without medical intervention. However, for men over 40 or those experiencing recurrent episodes of hematospermia, it is imperative to conduct a comprehensive medical assessment to eliminate any underlying health problems.

Causes of Hematospermia

Several possible factors can contribute to the presence of blood in semen:

  • Ruptured blood vessels: During erection and ejaculation, the pressure changes in the reproductive tract can cause tiny blood vessels in the seminal vesicles or prostate to rupture, leading to hematospermia.
  • Infections and inflammation: Hematospermia can be caused by sexually transmitted infections, urinary tract infections, or inflammation of the prostate or seminal vesicles.
  • Trauma: Injuries to the genital area, including sports injuries or accidents, can cause bleeding into the semen.
  • Medical procedures: Certain medical interventions such as prostate gland biopsy or vasectomy may temporarily cause hematospermia.
  • Structural abnormalities: Polyps, obstructions, cysts, or hemorrhages in the reproductive tract can also contribute to the presence of blood in semen.

Seeking Medical Evaluation

Men who notice blood in their semen should seek medical evaluation immediately, especially if they experience pain during urination or ejaculation. A thorough assessment by a man’s healthcare provider should include a conducting a complete medical history, physical examination, and diagnostic tests. These tests may include urine analysis, prostate-specific antigen (PSA) test, and imaging studies such as ultrasound or MRI to identify any underlying causes of hematospermia.

Treatment Options

In many cases, hematospermia resolves spontaneously without specific treatment. However, for persistent or recurrent cases, treatment options may be considered:

  • Antibiotics: If hematospermia is caused by an underlying infection, antibiotics may be prescribed to treat the infection and alleviate symptoms.
  • Medications: In cases associated with benign prostatic hyperplasia (BPH), medications such as finasteride (Proscar) may be recommended to reduce prostate size and alleviate symptoms.
  • Surgical intervention: In rare cases where structural abnormalities are identified, surgical procedures may be necessary to correct the underlying issue.


Hematospermia, while unsettling, is typically a benign and self-limiting condition. By seeking timely medical evaluation and understanding the underlying causes, men can alleviate anxiety and receive appropriate management if necessary. Effective communication with healthcare provider is essential for addressing concerns and ensuring reproductive health. If you experience blood in semen, seek guidance from a healthcare professional without delay.
