Blood in semen (hematospermia) can be frightening, but the vast majority of time, it's not cause for serious concern. Blood in semen is uncommon, and, most often, it goes away on its own.
If you're under age 40 and see blood in semen, you probably don't need to see the doctor as long as:
- You have no other symptoms
- You've had a recent prostate exam or vasectomy, which could explain short-term bleeding
- There isn't a lot of blood in the semen and it happens infrequently, then goes away
Make an appointment with your doctor if:
- You're 40 or older
- Blood in semen persists longer than three to four weeks
- You have other signs and symptoms, such as genital or urinary pain, pain during ejaculation, fever, difficulty urinating, or blood in your urine
- You have other risk factors, such as a history of cancer, bleeding disorders, trauma, or genital or urinary system malformation, or you've recently engaged in behaviors that put you at risk of sexually transmitted infections
