Should I be concerned about discolored semen?

Answer From Erik P. Castle, M.D.

Semen is normally a whitish-gray color. Changes in semen color might be temporary and harmless or a sign of an underlying condition that requires further evaluation. Possible causes, by color, include:

  • Reddish semen. This could be caused by the inflammation of the prostate or the glands that help produce semen. While red semen can be alarming, the cause is usually benign.
  • Yellow or green semen. This could be caused by an infection, jaundice, or the presence of vitamins or medication in the semen.

If semen discoloration is a new sign and it continues for more than a week talk to your doctor or see a urologist.
