I've noticed that my semen has a yellowish-green tint to it. Should I be concerned about discolored semen?

Answers from Todd B. Nippoldt, M.D.

Semen color and consistency can vary based on several factors, such as age, diet and frequency of ejaculation. However, yellowish-green semen may indicate a prostate infection. Semen is normally a whitish, cloudy fluid. It's usually quite thick just after ejaculation, but liquefies about 20 to 30 minutes later.

Changes in the appearance of semen are usually temporary and not a health concern. However, sometimes these changes can be a sign of an underlying medical condition that requires further evaluation. If these changes persist for longer than a week or two or if the color change is associated with other symptoms such as pain, fever, sexual dysfunction or blood in the urine, see your doctor for an evaluation.
