Effect of laparoscopic varicocele high ligation on the semen parameters of patients with unilateral varicocele associated infertility / 国际检验医学杂志

ABSTRACT

Objective To investigate the effect of laparoscopic varicocele high ligation on the semen parameters of patients with unilateral varicocele associated infertility.Methods A total of 56 cases of unilateral varicocele with infertility treated in our hospital from March 2014 to March 2016 were recruited into this study,who were all recepted laparoscopic high ligation.The content of lactic dehydrogenase isoenzyme X(LDH-X),semen fragmentation rate(DFI) and other seminal plasma were observed and compared before surgery and 3 months after surgery.Results The ratio of LDH-X in seminal plasma and whole sperm,DFI and LDH-X of seminal plasma before laparoscopic varicocele high ligation were significant higher than those after surgery,LDH-X of whole sperm was lower than that after surgery,the differences were significant(P<0.05).Sperm concentration,sperm motility,survivability of sperm,and sperm forward progression percentage before laparoscopic varicocele high ligation were significant lower than those after surgery.Conclusion The quality of semen,the content of LDH-X and sperm DNA integrity of unilateral varicocele with infertility could be improved by laparoscopic high ligation of the internal cord vein.
