RESUMO
Objective To investigate the application value of sperm nucleoprotein immaturity and sperm DNA damage detection in in vitro fertilization(IVF).Methods From Mar.2015 to Feb.2016,routine sperm analysis,sperm nucleoprotein immaturity and sperm DNA damage detection were performed in 102 patients with infertility,and the correlation between these parameters were analyzed.Results Sperm DNA fragmentation rate was negatively correlated with IVF optimal embryos rate and sperm viability(P0.05).Sperm nucleoprotein immaturity rate was not correlated with IVF optimal embryos rate and fertility rate(P>0.05),while was negatively correlated with sperm concentration(P<0.05).Conclusion Sperm DNA fragmentation rate could be closely correlated with IVF optimal embryos rate,which might be with prediction value in IVF treatment.
