Hematospermia-a Symptom With Many Possible Causes.

Abstract

Hematospermia, or blood in the ejaculate, is a symptom with many possible causes that often gives rise to worry. Precise figures on its prevalence are unavailable. It is most common in men under 40, and its cause is usually benign; nonetheless, even a single episode of hematospermia calls for a basic diagnostic evaluation. This review is based on pertinent articles re trieved by a search in PubMed with the key words "hemato spermia," "hemospermia," "ejaculation," "male semen," and "transrectal ultrasound." A diagnostic algorithm for hematospermia is described. The most common cause is iatrogenic trauma, in particular transrectal ultrasound-guided prostate biopsy to rule out prostate cancer. Urogenital infections are the second most common cause. Pathological changes of the prostate should be considered along with systemic causes, e.g., arterial hypertension or various hematologic disorders. A single event in men under 40 should be evaluated by precise history-taking, a meticulous physical examination including blood-pressure measurement, and urinalysis. Repeated episodes, or hematospermia in men over 40, calls for additional evaluation with further laboratory tests, imaging studies, and, in some cases, interventional diagnostic procedures. Further tests, preferably imaging studies, seem a reasonable way to detect or exclude potential causes of hematospermia, especially malignant ones. The treatment is directed at the underlying cause.
