Although there are many folk who think semen and sperm are the same thing – they are not! The only similarity they have is that they are dependent on each other for reproduction to take place.
Healthy semen is a whitish colour and is discharged via the urethra, through the penis when ejaculating. The seminal fluid is filled with millions of sperm, and its only function is to carry the sperm into the female reproductive tract so that the female egg can be fertilised.
