The Flagellar Mechanics of Spermatozoa: its Implication in Sperm Guidance

Experimental research using spermatozoa, a highly specialized cell with organelles involved in gene transfer, energy supply and cellular motility, has always occupied the forefront of studies in cell and reproductive biology. Several spermatological experiments have focused on the attraction of a spermatozoon toward the egg – sperm chemotaxis or sperm guidance. This process ubiquitously occurs in the reproductive system of many organisms. After its discovery in the late 19th century in plants, s
