Aberrant sperm protamination is linked to sperm dysmorphology and nuclear chromatin ***,its effects on sperm cytoplasmic maturation remain largely *** relationships of protamines,sperm morphology,DNA damage,and cytoplasmic remodeling were illustrated in this study to provide fresh perspectives on the mechanisms of male infertility.A total of 205 infertile males were allocated into 5 groups according to the percentage of spermatozoa exhibiting abnormal morphology within their *** concentration,motility,abnormal sperm morphology,cytoplasmic droplets(cDs),and excess residual cytoplasm(ERc)were analyzed according to the World Health Organization manual(2010).Sperm nuclear vacuoles(NVs)were determined by propidium iodide(pI)*** protamine expressions(p1 and p2)were detected by western *** damage was measured by acridine orange test(AOT)to calculate the proportion of sperm with single-strand DNA breaks(SSBs).Our data showed that sperm concentration and motility in infertile males significantly decreased with the severity of abnormal sperm morphology(both pp1 level,p1/p2 ratio,and SSB rate increased with the severity of sperm dysmorphology,whilst the p2 level decreased(all pcDs,and ERc were more common in males with sperm dysmorphology and positively correlated with the SSB rate(all pps between the SSB rate and the p1/p2 ratio were also significant(pprotamination may cause sperm dysmorphology and compromise male fertility by impairing sperm's nucleus and cytoplasm maturation,with the p1/p2 ratio potentially serving as a valuable indicator of sperm quality and male fertility.
