Abstract
The article reports the case of a 40-year old man with no history of significant illness. The semen analysis identified total asthenozoospermia. Ultrastructural analysis by electron microscopy showed multiple mitochondrial sheath and flagellum structure anomalies (incomplete/disorganized axoneme, absence of outer dense fibers and fibrous sheath) that explain the sperm immotility. As far as we know, the causes have still not been determined and the possibilities of reproduction involve the use of ICSI with low probability of success.
