Mouse sperm grouping

Harry Moore, an English biologist, has made a curious discovery: the sperm of the mouse come together to advance in the female's vagina. They form a group that can move quickly twisting the tails. Moore has made observations with basasagua sperm (Apodemus sylvaticus) and the results have been published in the journal Nature.

This grouping occurs two minutes after ejaculation and is undone at 20 minutes to fertilize the eggs. Moore believes that something similar to human sperm can happen, at least in invertebrates it is evident.
