Spermatozoa need to crane their necks to turn right to counteract a left-turning drive caused by the rotation of their tails, new research has found. The researchers discovered that all sperm tails (flagella) rotate in a counter-clockwise motion as they beat to enable them to move through and against the motion of a fluid.
