Avons-nous percé le mystère de la globozoospermie ?

Globozoocephaly was first described in 1971, and 35 years were necessary to identify the first genetic origin (SPATA16 mutation), despite the development of many mice models and the certainty of a genetic origin for this syndrome taking into account observations in many siblings. Despite the recent identification of the new genes PICK1 and DPY19L2, globozoocephaly is still a mystery. This syndrome is probably polymorphic, as suggested by electronic microscopic details, and it is associated with a poor success rate in assisted reproductive tehnology (ART). Further studies are needed to understand the mechanism leading to the globozoocephalia and to define new therapeutic approaches to turn around major spermatic defects associated with this syndrome.
