Mature spermatozoa are characterized by an head, midpiece and a long tail for locomotion. Now, researchers have found that a loss of the structural protein ACTL7B blocks spermatogenesis in male mice. The cells can no longer develop their characteristic shape and remain in a rather round form. The animals are infertile.
