What it is
Haematospermia means blood in the semen, which may make it look pink, red, or brownish. Although it can be alarming to notice, it is usually harmless and often settles on its own. In younger men (under around 40), it most commonly results from minor, benign causes — such as inflammation or infection of the prostate or other structures involved in producing semen, minor injury, or after certain procedures (like a prostate biopsy) — and frequently no specific cause is found. It is usually not a sign of anything serious in this group. In older men, or when it is persistent or recurrent, or comes with other symptoms (such as difficulty passing urine, pain, or blood in the urine), it is assessed more carefully, as, less commonly, it can occasionally be associated with other conditions, including — rarely — prostate problems that need excluding. So while haematospermia is usually benign, particularly a one-off episode in a younger man, it is worth having checked to identify any treatable cause and provide reassurance.
How it is treated
Assessment depends on the age, the pattern (one-off or recurrent), and any associated symptoms. A doctor will ask about the episodes and other symptoms, examine as appropriate (which may include a prostate examination), and often check the urine (for infection or blood) and, in older men or persistent cases, arrange further tests (such as blood tests including a PSA where appropriate, and sometimes imaging). Where a cause is found — such as an infection or inflammation — it is treated, which usually resolves the problem. In many cases, particularly a single episode in a younger man with no other symptoms, no serious cause is found and reassurance is given, as it typically settles on its own. Any underlying condition identified is managed accordingly. The reassuring message is that blood in the semen is usually harmless and self-limiting, but it should be checked — especially in older men or if it persists — to identify any treatable cause and offer reassurance.
