Blood in the semen
Blood in the semen is called hematospermia. It may be in amounts too small to be seen except with a microscope, or it may be visible in the ejaculation fluid.
Semen - bloody; Blood in ejaculation
Most of the time, blood in the semen is caused by swelling or infection of the prostate
or seminal vesicles. The problem may occur after a prostate biopsy
Blood in the semen may also be caused by:
- Blockage due to enlarged prostate (prostate problems)
- Infection of the prostate
- Irritation in urethra (urethritis)
- Injury to urethra
Often, the cause of the problem cannot be found.
Depending on the cause, other symptoms that may occur include:
- Blood in urine
- Fever or chills
- Lower back pain
- Pain with bowel movement
- Pain with ejaculation
- Pain with urination
- Swelling in scrotum
- Swelling or tenderness in groin area

The following steps may help ease discomfort from a prostate infection
or urinary infection:
