An intracellular, non-oxidative factor activates in vitro chromatin fragmentation in pig sperm
Biological Research, 2023 Background In vitro incubation of epididymal and vas deferens sperm with Mn2+ induces Sperm Chromatin Fragmentation (SCF), a mechanism that causes double-stranded breaks in toroid-linker regions (TLRs).
