Blood in the semen may be caused by inflammation, infection, blockage, or injury anywhere along the male reproductive tract. It may indicate disease or a problem within the urethra, testicles, epididymis, or prostate.
Blood in the semen is usually the result of inflammation of the seminal vesicles, and will usually go away spontaneously. Often, the cause can not be determined. If the blood does not clear and ejaculate is persistently stained with blood, more extensive tests should be done, such as urinalysis and culture, semen analysis and culture, and ultrasound of the seminal vesicles.
Minor injuries may be treated with rest, applying ice, and monitoring symptoms. Major injuries may require reconstructive surgery.
Infections can often be treated with antibiotics taken by mouth (or intravenous antibiotics if symptoms are severe).
Blockages are typically treated with surgery. If cancerous tumors are the source of obstruction, radiation and/or chemotherapy may also be indicated.
Always call your doctor if you notice any blood in semen.
