Sperm integrity is critical for normal mitotic division and early embryonic development*

Abstract excerpt

The human zygote relies on the paternal gamete to provide the centrosome component essential for the first mitotic division. It is not known whether normal centrosome function requires an intact spermatozoon, or whether donation of an isolated paternal centrosome component can result in normal zygotes and embryos. To explore this possibility, mature human oocytes were microinjected with either intact or dissected...
