Review demonstrates advanced physiological sperm selection methods reduce DNA damage risks in assisted reproduction, suggesting improved outcomes for intracytoplasmic sperm injection.

Key Points

To assess the biological limitations of conventional sperm preparation techniques and evaluate modern physiological methods designed to isolate undamaged spermatozoa for assisted reproduction.
Evaluated conventional isolation techniques, including swim-up, density gradient centrifugation, and glass wool filtration, relative to physiological barriers in the female genital tract.
Reviewed advanced sperm selection platforms based on high-magnification morphology, electrical charge, and molecular binding affinities such as Annexin V and hyaluronic acid.
Conventional preparation techniques fail to adequately eliminate spermatozoa with DNA damage because they do not mimic natural female reproductive tract selection barriers.
Advanced molecular and charge-based modalities, including magnetic cell sorting and hyaluronic acid selection, provide enhanced isolation of mature spermatozoa with intact chromatin.
