Analysis of the spermatic vein blood gas from the infertility patients with varicocele

Objectives To investigate the nosogenesis of why varicosele can result in infertility.Methods The left spermatic and peripheral vein blood was taken from 50 infertility patients with varicocele and 40 normal cases,and the blood gas was mearsured.Results (1) The PH,PO2,SaO2,HCO3-of the left spermatic vein blood was lower than that of the peripheral vein blood from the male with varicocele (P ＜ 0.05),the PCO2,K + of the left spermatic vein blood was higher than that of the peripheral vein blood from the male with varicocele(P ＜0.05),but the other indexof them was not significant(P ＞ 0.05).(2) The PH,PO2,SaO2,HCO3-of the left spermatic vein blood from the male with varicocele was lower than that from the normal male(P ＜ 0.05),the PCO2,K + of the left spermatic vein blood from the male with varicocele was higher than that from the normal male(P ＜0.05),but the other index of them was not significant(P ＞ 0.05).(3)The density and motility rate of sperm fromthe male with 4 varicocele was lower than that from the normal male(P ＜ 0.05),and the abnormal rateof sperm from the male with varicocele was higher than that from the normal male (P ＜ 0.05).Conclusions The depression of the PH,PO2,SaO2,HCO3-and the rise of the PCO2,K + in the spermatic vein blood from the infertility patients with the varicocele may be the cause of the depression of the density and motility rate of sperm and the rise oftheabnormal rateof sperm which can result in infertility.
