Breeding
Not much is known about the breeding biology of the Indonesian Javan rhino, as it has never bred in captivity. Mating takes place each year but is only successful every 4-5 years. The mating season occurs roughly from July to November, and the gestation period is about 16 months.

The single offspring is active soon after birth, being suckled by the mother for at least one and perhaps two years. In Ujung Kulon, females become sexually mature between the age of 6 and 8, and research suggests that they mark their territory with urine in order to breed. The young stays with its mother for 1-2 years.
