By Mayo Clinic staffBlood in semen is a frightening sign, but it rarely indicates a serious disease, particularly in men under 40.
Many men experience single or occasional episodes of blood in their semen, and the problem can appear at any age. Sometimes, blood is persistently visible in the semen over the course of a few months or longer.
The amount of blood in semen varies, depending on the cause. You may notice no more than a drop or streak of blood in semen, or much of the ejaculate could look bloody.
Although this sign is usually short-lived, several tests are available to pinpoint the likely cause of blood in semen and give guidance for treatment if needed.
