The : The brown color of your semen can be attributed to the presence of old blood. Red blood chnages to brown in color, after a while. The presence of blood in your semen could have been caused by trauma, infection, inflammation or blackage in the reproductive canal/urethra or testicles. It is very important to see your doctor if this persists.

You : You have blood in your sperm. It is mostly a benign condition, known as hemospermia. However if it persists, it could indicate you have an infection of seminal vesicle (the pouch that store sperms) or in patients that are older (over45), you should see your doctor to make sure you are not at risk of prostate cancer ( get a psa test) and rectal examination.
