At this time, the deer's antlers are hard and durable, making them useful for warding off predators or sparring with other male deer in hopes of winning a mate. A more extensive study is needed to fully correlate growth rate of antler, with sexual cycle, age, and tine length until the rut without cutting the antler.

From then on, annual renewal of subsequent antlers enters a well-defined cycle: casting of previous hard antler and regeneration of a new soft antler in spring, with rapid antler growth (up to 2 cm/day) and maturation in summer, then full antler calcification and velvet shedding in autumn, followed by the bare bony antler phase in winter" A third factor that affects deer antler growth and development is nutrition.
