do male reindeer lose their antlers in the winter

Male reindeer do lose their antlers in the winter, just like female reindeer. It's a natural process that occurs to help them survive the cold winter months. The antlers are made of bone, and they can grow quite large during the summer and fall, so they require a lot of energy to maintain. In the winter, the male reindeer shed their antlers to conserve energy and allow their bodies to focus on staying warm and finding food. The antlers will regrow in the spring.
