Impact of the Z potential technique on reducing the sperm DNA fragmentation index, fertilization rate and embryo development.

Background: In assisted reproduction procedures, we need to develop and enhance new protocols to optimize sperm selection. The aim of this study is to evaluate the ability of the Z potential technique to select sperm with intact DNA in non-normospermic patients and evaluate the impact of this selection on embryonic development.

Methods: We analyzed a total of 174 human seminal samples with at least one altered parameter.
