ABSTRACT
<p><b>OBJECTIVE</b>To identify the differentially expressed proteins in seminal plasma between subjects with normal fertility and those with delayed semen liquefaction by proteomic techniques.</p><p><b>METHODS</b>Semen samples of 6 patients with delayed semen liquefaction and 11 subjects with normal fertility (control group) were collected. Seminal plasma were separated and examined with surface-enhanced laser desorption/ionization time of flight mass spectrometry to compare the protein expressions between the two groups.</p><p><b>RESULTS</b>Compared with normal control group, 19 proteins were differentially expressed in the patients including 6 proteins with significant differences between the two groups, with m/z of 8696.621, 9770.076, 9512.309, 10202.64, 2941.903, and 9617.759, respectively (P<0.01).</p><p><b>CONCLUSION</b>Screening of differentially expressed proteins in seminal plasma may help understand the mechanism of delayed semen liquefaction for its potential clinical intervention.</p>
