Question

Blood in semen: What are the causes?

What causes blood in semen?

Answer

from Todd B. Nippoldt, M.D.

Blood in ejaculated semen (hemospermia) is relatively uncommon and rarely serious. In most cases, the cause can't be determined, and the problem goes away without treatment. However, known causes of blood in semen include inflammation, infection, and blockage or injury to the prostate gland or seminal vesicles. Also, following a prostate biopsy, it is common to have blood-tinged semen for four or five subsequent ejaculations.

A doctor may be able to determine the cause of blood in semen based on:

  • Physical examination
  • Urine tests (urinalysis)
  • Blood tests

Treatment is directed at the underlying cause when possible. If a man notices blood in his semen, he should consult his doctor.
