According to recent research, the speed with which the sperm travel up the egg does not depend directly on the anatomical shape they possess.

As for the theory that denies the aerodynamic profile and a tail longer leads to greater speed in the sperm, according suggests a study by the University of Sheffield (UK) as published in “BMC Evolutionary Biology.”

The researchers focused on studying the evidence linking the shape of the sperm with the speed with which they move. Therefore indicate that the length of the head and tail or a whole does not bring any benefit to the sperm in their race to the egg.

“Actually, the goal of evolution is in the lengths of the sides on the sperm front of its total length,” says researcher Stuart Humphries.

This recent discovery implies that can not be attributed the evolution of sperm no longer a competitive advantage that the length alone can provide. In contrast, a small size and low speed of swimming makes the sperm has more power when it comes to swim to destination.
