Although only males produce sperm, that does not mean that all sperm is male. There are two types of sperm: male and female. Male sperm carry the 'y' chromosome; female sperm carry the 'x' chromosome. If all sperm where male, then there would be no females born. Thus, the difference between male and female sperm is that male sperm carries the 'y' chromosome and produces male offspring and female sperm carries the 'x' chromosome and produces female offspring.
Sperm and egg cells are gametes, or reproductive cells. The sperm is the male reproductive cell. The egg is the female reproductive cell.
The male gonad is the testes. Testes produce the hormone testosterone, which is responsible for male sexual characteristics, as well as sperm cells for reproduction.
