My textbook says "fructose and other nutrients" from fluid made by the seminal vesicle. Prostate gland adds "citric acid, calcium and various enzymes."

The energy for sperm to swim is provided by mitochondria in the sperm (mitochondria are often called the powerhouse of the cell).

However, these mitochondria in the sperm are almost never incorporated into the fertilised egg, which inherits its mitochondrial DNA from the mother.
