| 1 | Estimate of oxygen consumption and intracellular zinc concentration of human spermatozoa in relation to motility显示文摘Aim:To investigate the human sperm oxygen/energy consumption and zinc content in relation to motility.Methods:In washed spermatozoa from 67 ejaculates,the oxygen consumption was determined.Following calculation of the total oxygen consumed by the Ideal Gas Law,the energy consumption of spermatozoa was calculated.In addition,the zinc content of the sperm was determined using an atomic absorption spectrometer.The resulting data were correlated to the vitality and motility.Results:The oxygen consumption averaged 0.24μmol/10^6 sperm×24h,0.28μmol/10^6 live sperm×24h and 0.85μmol/10^6 live & motile sperm×24h.Further calculations revealed that sperm motility was the most energy consuming process(164.31mJ/10^6 motile spermatozoa×24h),while the oxygen consumption of the total spermatozoa was 46.06mJ/10^6 spermatozoa ×24h.The correlation of the oxygen/energy consumption and zinc content with motility showed significant negative correlations(r=-0.759;P<0.0001 and r=-0.441;P<0.0001,respectively).However,when correlating sperm energy consumption with the zinc content,a significant positive relation(r=0.323;P=0.01)was observed.Conclusion:Poorly motile sperm are actually wasting the available energy.Moreover,our data clearly support the “Geometric Clutch Model”of the oneme function and demonstrate the importance of the outer dense fibers for the generation of sperm motility,especially progressive motility. | Ralf R.Henkel Kerstin Defosse Hans-Wilhelm Koyro Norbert Weissmann Wolf-Bernhard Schill | 2003 | Asian Journal of Andrology2003，5，1： | 2 |
