This is the finding of blood in the semen and is relatively common. The bleeding is believed to come from either the prostate or congested seminal vesicals and is invariably self limiting and without consequence. Hemospermia is common after a TRUS/BX (trans rectal ultrasound and needle biopsy ) of the prostate and may last several weeks. In the absence of any other significant urological symptoms or signs, additional evaluation is not helpful, apart from a digital examination of the prostate,a urinalysis and a serum PSA (prostatic specific antigen). If these tests are normal, the patient can be simply reassured.
