[Total asthenospermia with an ultrastructural anomaly of the flagellum in two sterile brothers (author's transl)].
The two sterile brothers were found to have the same sperm abnormalities. The flagella were short or absent. The constituent elements of the flagellum were disorganized, and the axone structure was disturbed. These abnormalities give rise to a problem of explaining the genetic origin of certain sperm defects similar to those found particularly in mice.
