What is hematospermia (blood in the semen)?

Hematospermia (also called hemospermia) is the presence of blood in the semen. Hematospermia may naturally cause concern for men who experience it. However, it is not likely to be a sign of a major health problem.

Is hematospermia a common condition in men?

It is unclear how common hematospermia is because men usually do not examine their semen after ejaculation.

Hematospermia can affect men of any age, but it is more common in men aged 30 to 40.

What are the causes of hematospermia?

The most likely cause of hematospermia is a seminal tract infection or inflammation. Less likely causes may include:

  • Sexually transmitted infections (STI), such as gonorrhea, chlamydia, or a viral or bacterial infection
  • Blood disorders, such as clotting disorders or sickle cell disease
  • Recent medical procedures, such as vasectomy, prostate biopsy, or cystoscopy
  • Tumors (cancerous) and polyps (non-cancerous or benign growths)
  • Testicular or prostate cancer (rare)
  • Other medical problems, such as high blood pressure, human immunodeficiency virus (HIV), liver diseases, and leukemia (blood cancer)

What are the symptoms that can be associated with hematospermia?

  • Blood in urine (hematuria)
  • Burning sensation when urinating
  • Trouble emptying a bloated bladder completely
  • Pain in the bladder
  • Painful ejaculation
  • Discharge from the penis or signs of a sexually transmitted disease (STD)
  • Fever, higher-than-normal blood pressure, and rapid heart rate
