Semen is required: Semen is required, because sperm is required. The sperm is in the semen. An egg is required also, and the egg and sperm have to both be at the same time and place. If there is no sperm, or no egg, or they miss one another like two ships passing in the night... then nothing happens. That's just the way it is.
