Argali reach breeding maturity at two to three years of age. Rutting may occur from October to mid-January, generally lasting longer in lower elevations. In rutting herds, both rams and ewes attack others of their own sex, exerting dominance by ramming each other with their horns. Although such groups engage in lamb-like play, the combat of a pair of mature males is a serious business. The rams slam into each other, with their fore legs up in the air, exerting enough force to be heard up to away. Often, the older males (over six years of age), which are also often the largest, end up the dominant ones and younger males are chased off once the ewes are in estrus. Once dominance is established, the top rams begin approaching ewes and smell their urine to determine their receptiveness. The ram then repeatedly approaches the ewe and forcibly mounts her. Mating commences around two to three weeks after the rutting begins. Rams may remain in the company of ewes for up to two months after the rutting period is complete.
