Indian gazelles are polygamous. Males are extremely territorial and defend their resources with their horns. Male-male competition is frequently observed during the mating season, and males aggressively defend females from other males before mating. Mating begins as a male gazelle touches the underparts of a female gazelle with a stiff leg, called “laufschlag.” When complete, copulation ensues.
Mating System: polygynandrous (promiscuous)
There are two breeding seasons throughout the year, one at the end of the monsoon season from late August through early October, and the second in late spring from March to the end of April. Indian gazelles have a gestation period of 5 to 5.5 months. Females generally give birth to one offspring, but twins have been frequently reported. A majority of births occur in April. Offspring are precocial and are weaned at about 2 months of age, though they may stay with their mother for up to 12 months when she has another offspring. Female Indian gazelles first conceive when they are yearlings.
