Since the sperm needs to travel inside the female reproductive system and enter the egg, it has a tail. Tail helps the sperm to move forward (like a snake) instead of moving in circles.
There are other parts of the sperm, like head, neck, middle part and tail.

- Middle part supplies energy to the sperm
- Tail helps the sperm to swim in the female genital tract.
