What could cause discolored semen?

Answer by  Zoe (2369)

If it is yellowish, brownish, or greenish it is possible that you have a prostate infection. If it isn't some variation of white and cloudy, it might be time to see a doctor to make sure there isn't something serious going on, especially if this has been going on for more than a couple of weeks.

Discolored semen can occur as a result of contracting a sexually transmitted disease. Various sexually transmitted diseases can cause this, including, but not limited to, gonhorrea, siphillys, chylamidia, etc... If semen is red, it is possible that a blood vessel inside the penis has also ruptured. This may require immediate medical attention.
