Blood in the semen (Haematospermia)
Seeing blood in the semen (haematospermia) can be startling. It rarely, however, signals a serious problem, especially in men under the age of 40. Haematospermia often doesn't last long, as it's usually a self-resolving problem. Possible causes of haematospermia include inflammation, infection, enlarged prostate, tumours and very rarely, blood disorders. If haemaotspermia persists, your GP may wish to refer you for further evaluation. This might include a physical examination of your prostate, a PSA blood test, an ultrasound and a semen test for infection.
