Hello Swapnil,

There are few animals that are sterile, i.e., they cannot reproduce. There are few animals in which males are sterile and females are not and vice versa. The sterility is mostly seen in the hybrid animals.

The few examples of animals that cannot reproduce are :

1. Mules

2. Hinny

3. Tigon

4. Zorse

5. Liger

However, mostly hybrids cannot reproduce with their own species but  they can reproduce by cross breeding. Some examples of such animals are Leopons, Wholpins, Beefalo, Pizzly, Dzo, Cama, etc.

Best Wishes.
