A normal ejaculation should...
- contain 40-600 million sperm that can cover the head of a pin.
- be a cloudy white fluid with a chlorine type smell.
- taste slightly sweet due to fructose in sperm.
Gag alert: Yellow or Green Colored Semen is a sign of infection, most likely the result of gonorrhea. Foul smelling semen is almost always a symptom of infection.
