[Investigation of seminal plasma. Value of nuclear magnetic resonance].

Abstract

The purpose of this study was to investigate whether the measurement by NMR of some biochemical markers such as glycerylphosphorylcholine (GPC), glycerylphosphorylethanolamine (GPE), citrate, and lactate in human seminal plasma may be able to differentiate spermatogenic failure from obstructive azoospermia. The peak area ratios citrate/lactate, between normozoospermic and spermatogenic failure or obstructive azoospermia groups were significantly different. We have also found significant differences in GPE/GPC peak intensity ratio between spermatogenic failure men and obstructive azoospermia patients (P < 0.001). This ratio appears to be a very important parameter to differentiate spermatogenic failure from obstructive azoospermia. These results demonstrate the potential use of 1H NMR on human seminal plasma in male infertility evaluation and such analysis may be used to elucidate the molecular basis of the human pathologic seminal plasma disturbances.
