what is the sperm colour
psnetwork111987. Sperm is typically a milky color, but it is normal for it to have a yellow tint to it. It is based mostly off of your diet and how frequently you ejaculate. If your ejaculate has red or brown streaks in it, that is blood and a sign of an injury.ust the other day I have noticed that the color of my sperm is a bit changed. It was a bit brownish and my girlfriend who also noticed it thinks I got some sexually transmitted disease. Please tell me does sperm color really plays that big role in detecting these diseases as she thinks.
