Every year we kill 2 or 3 bucks that are still in velvet. None of them have had testicals. This year we have killed 4 already and there is definately another that has been spotted. The exception is that one of the furry heads this year had testicals and was rutting! Up to that point, we had assumed that the velvet bucks were sterile but now we are not so sure. My question is this....What causes this? Is it some sort of injury? None of the deer that we have killed like this have any scars or evidence of any major injury. Or is it genetic? We are completely dumbfounded by this.

Thanks for your replies.
