Analysis of correlation between sperm indicators and early spontaneous abortion after in vitro fertilization / 国际检验医学杂志

ABSTRACT

Objective To explore the correlation between the sperm indicators and early spontaneous abortion after in vitro ferti ‐lization(IVF) .Methods 251 couples receiving IVF ,were retrospectively analyzed and divided into the research group (98 couples) and control group (153 couples) according to whether spontaneous abortion occurring .The male′s indicators of sperm DNA frag‐mentation index (DFI) ,sperm nucleoprotein immaturity rate ,percentage of normally morphologic sperms ,etc .in the two groups were analyzed .Results DFI ,percentage of normally morphologic sperms ,sperm concentration ,motility and forward motile sperm had no statistical differences between the research group and the control group (P> 0 .05) ;while the sperm nucleoprotein immaturi‐ty rate of the research group was significantly higher than that of control group ,the difference was statistically significant (P <0 .05) ;the sperm nucleoprotein immaturity rate had weak correlation with spontaneous abortion in early pregnancy (P < 0 .05) . Conclusion The sperm nucleoprotein dysmaturity is correlated with the spontaneous abortion in early pregnancy .The sperm nucle‐oprotein immaturity rate could be used to evaluate the risk of spontaneous abortion in early pregnancy after IVF .
