The adult toad reproduces sexually. During courtship, the male makes a croaking sound which attracts the female which is usually swollen with eggs.

The male toad grasps the back of a receptive female with the help of nuptial pads associated with forelimbs and releases sperm. This stimulates the female to lay about 500 to 5000 eggs which the male fertilizes as they shed sperm over them.
