Magnetic-activated cell sorting is not completely effective at reducing sperm DNA fragmentation

摘要

Morphology of Giemsa stained spermatozoa following the sperm chromatin dispersion test (Halosperm G2) resulting in the differentiation of three main sperm nuclear morphotypes: (1) normal sperm free of sperm DNA fragmentation and displaying large or moderate sized haloes around a compact core; (2) fragmented sperm displaying small or absence of haloes and (3) fragmented (degraded) sperm showing varying size of the faintly stained nuclear core ( – ).
