Discolored semen: What does it mean?
Medically reviewed on July 18, 2018
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.
