[Maturation of ram spermatozoa. Preliminary study of the flagellar movemnent characteristic of the transitory forms of the epididymal corpus].
Mammalian spermatozoa acquire the ability to move forward during epididymal maturation and the corpus occurs as a critical region where all the patterns of movements can be observed: immature, 'erratic' and mature. The absence of coordination of the flagellar movement of the transitory forms provides a difference in the initiation sites and the waves propagation between the two sides of the axonema. The mechanisms that may be required to activate selectively the tubulin-dynein system on the two sides of the flagellum during the initiation of the movement of immature sperm in mammals are unknown.
