Did early mammals turn to night life to protect their sperm?

In the Triassic period, early mammal ancestors (therapsids) turned to a nocturnal lifestyle to overcome thermoregulation challenges. Their rapid endothermy led to elevated body temperatures, posing a risk to sperm quality. By becoming active at night, these mammals could preserve sperm quality.
